Well, the time has finally arrived when I rebuild my MG Midget Mk1. The car has been off the road since 1997, dry stored in a garage or outside under cover for the last 11 years. Pressures of work and a growing family, plus the distractions of an MGBGT, Mazda MX5 and a Range Rover. It failed its MOT with structural problems (rust) on the H frame (below the engine) and the front splashguards (footwells) and at the rear. The bodywork – rear wings and A posts were all rotting away too, though the sills were in pretty good nick following the last full body restoration in the late 70’s.

After placing a Wanted ad on the MG enthusiasts a nice chap by the name of Alistair Shaw got in touch to tell me of a completely restored shell lurking in Suffolk. I got in touch with the owner, Dominic LeFanu of MG Restorations, got him to send me lots of photos, and we agreed a price. The shell had no V5 but was complete and in very good order, with new front and rear suspension and an Ashley fibreglass front end. I sold the latter on through eBay which helped to make the deal much better value. When you think a heritage shell for a Midget is @ £4500, then there would be a pile of conversion work to make it a Mk1, the price of £1900 for this shell, less the £330 I got for the Ashley front end made a good price and worth-while exercise. The cost of sorting out my existing shell ( I am rubbish at welding and bodywork) would have been much the same (£4500). An uneventful trip with a trailer on the back of the Rangie to Suffolk saw me back home with the new shell. A couple of months passed as I waited and waited for the right time.
Plan was to reuse as much as possible, given that most of the mechanicals and ancillaries were in better nick than the car itself, but to treat myself to a new wiring loom, and to convert to disc brakes on the front.
Colour and trim, planning for MG Nightfire Red Pearlescent, with a cream interior. Undecided on whether to refit all the chrome / bumpers, and may decide to paint all the chrome/ally trim in Old English White or similar. The car has never been “standard” since I have had it (1979) and I may as well have it as I want it
Started: October 17th 2008
I decided to work from the front to the back.
Stripped the front trim and centre trim from the bonnet, then removed the bonnet. Worked through removing the front scuttle and the wings. In all only had a problem with 3 bolts, not bad after 20 years.
The two bottom bolts that tie the wings to the front scuttle were seized solid, so I decided to remove the wings and the scuttle as one, and tackle them in comfort (hacksaw!). A wing to the top of the scuttle bolt also sheared off on removal. Surprisingly all the wing bolts/screws to the footwell came out with ease. Secret bolts securing the wing to the bulkhead, at the top of the wing and underneath. I had previously fitted an oil cooler in situ, and of course it wouldn’t comoe out of the small space it occupied in the scuttle, so the pipes were disconnected from the engine, sealed off, and it all came out together. Oil black and mucky. Inside the distributor cap it looked just like the day I last used it.
Every nut and bolts and screw is all going into one pot, hope I don’t live to regret this! but planning to replace most of them with galvanised or zinc plated on rebuild
All trims and lighting removed, along with bonnet locks.

With the wings and the front scuttle out of the way I got on with the removal of all the ancillaries, working first the drivers side, removing all electrical and mechanical items, moving the loom out of the way as I went. Lots of additional wires for extra things! (horns, screen pump, fuel pump, stereo, etc). Removed exhaust and carburettors at the manifold. All water pipes came off easily, and still about a pint of water in the cooling system, beautifully clear blue as well. Dynamo and starter all came off easily, the bendix still working, a little stiff, but a dash of WD40 made it like new
Hoping to be able to get the engine out using jacks and scaffold boards, as no hoist available. Continued to strip down the engine bay, its got fiddly now. little bits and bobs. Engine and gerabox out went fine.
MG Midget – Engine OutSee photo »
Removed exhaust. Jacked up the engine a bit, tied the gearbox onto the bonnet supports to hold it up, released the bellhousing bolts, more jacking and a good tug. needed a serious yank to get it up onto the steering rack, then slide it down a scaffold plank to the ground. Almost went as well for the gearbox, undid the two bolts on the tunnel, and then the two bolts going up thorugh the floor. Put jack under the box, removed rope, and gave a similar yank. Oops, fell of the jack and oil everywhere. Fortunately, not as heavy as the engine. Dismantled all my brake piping and removed master cylinder (now that will be a job to refurb), removed engine mountings, windscreen (finally shifted the big philips, without the need to go get an impact screwdriver) and doors (strangely crosshead bolts holding these in, not on the new body). Good days work, can start on the interior next. Oh the heater box crosshead screw refused to budge, so they came off with a chisel and Birmingham spanner.
Went to work on the interior, removing all the carpeting and trim. The dash surround was going well until I had one nut that was the wrong size for every spanner i had in the garage. Finally took off the steering wheel to get at it properly! Both footwell carpets were pretty rotten, but the floors were in actually fairly solid nick thanks to the glassing I had done all those years ago. Slowly, slowly everything came out, tackled the dash last, which is only held on by three bolts above and two below. Some gentle tugging and it all came out in one piece, instruments, loom, radio the lot.
MG Midget – Interior Reference & RemovalSee photo »
Back end and brakes. Petrol tank bolts all came off, but were stiff, bumper bolts fought for some time. rear lights in good nick, and number plate light all came away OK. Found a nice rusty hole middle of the boot though. Removed UJ bolts on the propshaft and squeezed myself under enough to undo the hidden nut holding on the hand brake cable – why put it there. Whilst underneath I noticed that I had previously fitted SPAX rear shock absorbers, so they had to come off too. Dismantled one rear brake, but again no right sized spanner to remove the bolt holding the rear brake cylinder on. Time will provide the solution to this. Now both bodyshells are looking very similar.
Had a big tidy up in the garage, tucked some body parts away in the loft, and stripped the wings and doors of all trim and electrics. Been looking at the prices of new/used parts so will need to be doing a far bit of refurbishment. next job is really to make a start on the new bodyshell, find a good sprayman and agree a price. Still undecided as to whether to go for tartan red again, or to go a bit more custom and have Nightfire metallic or similar. I guess cost will be the issue here. Also need to decide what to do about the brakes. probably need a new master cylinder so should I upgrade and us 1275 masters given I will need new front calipers.
More tidying up, piled up the carpets and trim, wrapped in cardboard and stored in loft for later. Hood, tonneau and seats likewise. Removed the drivers side shock absorber, and loosened the rear axle fixing bolts on both sides Cut through the rubber axle straps, first lazy thing I have done! Removed front brake drums and dismantled brakes, removing brake cylinders and pipework. That’s just a bout it for dismantling, other than it stopping being a rolling shell. Will push it out into the front garden tomorrow so it can live under a sheet. Photos taken to see if I can flog it on eBay or via MGOC – Restorations. Found a good frogeye spares website, so should have no problems getting all bits and pieces needed.
Moved the old shell out of the garage, and place it out under a tarpaulin. Put it up on ebay as well, and have two watchers. We shall see!
Old bodyshell sold on eBay for £152.50 ! Now have to hope for some reasonable weather in order to remove the front and rear axles and get it up on stands awaiting collection. Started working up a parts and supplies list as well. Purchased a set of calipers and pedal box with master cylinders from a 1275, to improve the braking. Some work required to get the pedal box fitted as is a different shape. Still tempted to do my own respray with aerosol cans. I know its not recommended but reckon its worth a try, even if it has to go off for a final spray over. Some good help regarding under body protection from the internet, with a choice of products, one for stone chip prevention that can be oversprayed, the other for salt and corrosion protection for the bits that do not need to be shiny. Etch primer is also available in cans but won’t be getting it from Halfords at £12 a can! Also bought a couple of aerosol can triggers to improve spraying control. The cost of Christmas is going to get in the way!
MG Midget – ShellSee photo »
Moved bodyshell back onto the drive, in order to remove axles.
On a freezing cold evening, in the dark, removed the rear axle. please I released all the bolts earlier on in the dismantle, so it was a simple job, but cold. Upper Link bolts siezed solid, so they will have to stay. Released track rod ends and removed steering column
Removed steering rack, and both front suspension units (remember to take the bolt on the damper arm out in order to release it from the top trunnion!) Removed both rear springs, but reinforcing plates wouldn’t budge, probably been welded on at some point in the past, so will have to get two new ones, as the new shell doesn’t have them. Bought spanner (19/32th) to remove rear brake cylinders. One undid, the other was so corroded I had to bang a 9/16 on to get it off. One cylinder came out easy, the other required force! That’s it now, time to get on with the rebuild!
Finished: December 6th 2008
Got on with sorting the new shell, need a damn good clean up after sitting in a barn for 10 years. Pleased to find no rust anywhere and everything as it should be. Measured up and cut out some metal around the pedal box, to allow for the different / newer pedal box and master cylinders for the disc brakes. The originals are just not good enough for today’s motoring, and more expensive.
MG Midget – New Shell PrepSee photo »
Time passes, car gets covered in old boxes and stuff my wife doesn’t want in the house any more. Fast forward to 2010 !
Prepared all those little bits, the cowl things inside the engine bay (you know on one side it holds the washer bottle), the brake pedal blank, number plate light, gear lever turret, boot and bonnet hinges, and primered and sprayed with Nightfire red and lacquer.
Prepared the engine bay and the heater channels and sprayed them up too.
Prepped up the bonnet, wings, doors and boot, but only in primer for a trial fit
Fitted all the panels. This is normally easy, but I found with the wings and the front scuttle i had to take a wrap around approach: fit drivers side wing, then fit scuttle, then fit passenger side wing to scuttle then fit passenger side wing to car. Only way I could get it to go all together.
MG Midget Panels Trial FitSee photo »
Time passes again, car fills up with bags and boxes again. fast forward to 2013!
Started to clear up my clutter, made several trips to the skip, shifted stuff out of the garage into the garden shed, and began to find room in my garage for the first time (hadn’t helped that I had filled it up with 12 Range Rover tyres! Built some new shelves with some old shelving from the skip at work, which got things out of boxes. Also constructed a trolley support for the MG so I could move it around. I used an old catering trolley, cut down to its flatbed bottom shelf. really good castors. Then two 8ft lengths of 4 x 2 and a 5ft length of the same. Screwed this all together and placed on the trolley. The two long lengths run from the bumper mounts at the front of the H framed through to the diff tunnel, and the 5ft length and spacers supported the two 1/4 elliptic spring mounts.
MG Midget – TrolleySee photo »
I then did a quick hand sand with 100 grit on the entire interior and boot, vacuumed out, then primered the whole area. Once dry I masked up with newspaper the interior, the boot and the engine bay.
Now with all the panels on the car I took to it with 100 grit (non clogging) sandpaper to knock off all the high spots and sand down scratches and imperfections. I used a power sander for this, then followed up by hand.
MG Midget – Mask up and Sand down 100 gritSee photo »
Next step was to vacuum off all the dust, then Wet and Dry 400 grit, buy hand, with lots of water to start getting a smooth finish.
MG Midget – 400 gritSee photo »
Yes, it has been a while, but finally prompted to action by a warm April. Over the winter I constructed a spray tent in the garage using polythene dust sheets, and got the car sanded down with 1200 grit and applied primer inside and out. had a good couple of months to dry. But towards the end of April with good weather I pushed the car outside and applied the first coat of Rover Nightfire Red. Takes some practice to get a a good shine on it, will need to take my time with the final coat of colour. Warmer weather helps to prevent runs. Will not be sanding down the paint as this prevents the sparkly effect.

4 & 6th
Where did the summer go? Paint and lacquer sitting on the shelf finally got the better of me. Given last week offered us lovely warn weather, and with a week off, the MG was rolled out into the drive, given a quick clean and rub down with a tack cloth and another good coat of paint, using a further six cans. Applied three coats of lacquer to one of the rear wings in order to test the shine, which after a further sand down with 1000 grit paper and a quick buff with Meguairs Ultimate produced a mirror finish
The rain then descended for the next two days, so was confined to the garage with the gas mask (Did a good job, btw). One of the few problems with cans is the drips and runs, these needed rubbing down and then the car was sprayed all over again with a further four cans, followed by three large cans of lacquer. Bloomin’ drips from the lacquer cans as well will require further rubbing down and respraying.
Several purchases also made over the summer, new mesh grille, grille surrounds, water pump, rear brake cylinders (again!), heater tap, engine gasket set, clutch master cylinder, slave cylinder, brake master cylinder. Buying things bit by bit, every now and then helps to ease the financial pain. 😉
7th October 2015
Hopefully painting finished today, @ 5 light coats of Nightfire Red, followed by 6 light coats of clear lacquer. This has left me with a dull finish (by design)
Now for the magic! I did a test area on the rear wing next to the door. 1200 grit wet and dry, lightly sanded to a dull finish. Followed up by a brisk polish with Meguairs Ultimate and my Silverline Polisher, starting at speed 1 then moving up to 4.
Hopefully the difference is visible on the photos. I have a lot of lacquer left over so must do the insides as well, then allow the paint and lacquer to harden properly over the next dew days, before going for broke over the whole car with sanding and polishing (will then get washed and polished too!)
8th August 2017
Where does the time go?
Done a lot of work on the body since October 2015, my daughter thinks all I do is spray paint on the car then sand it off again, to only then spray more paint on the car! However, topsides are now done, although I am less than happy with the end result, will probably take the car to “my little man” who has a workshop on a local farm and specialises in Classics, for a spray and shine finish.
All the undersides are also complete, cleaned and sanded down, two coats of stone chip undershield, followed by 2 x primer, 2 x top coat, 2 x lacquer.
That’s it, not painting the body anymore. Let me get to work on the mechanicals.
Have prepped up the steering rack, new boots and track rod ends, all cleaned up. Rear axle much the same, and carried out a quick restoration on my Spax rear shock absorbers and mounting plates. Front suspension, mainly dampers and wishbones also got the gloss black treatment.
Time for a gallery of the bodywork, the photos and lighting do flatter it.

11th August 2017
Have warmed up the waxoyl and sprayed all the cavities and wing and boot corners, making a mess of the garage floor in the process. Also doused the rear springs with the stuff.
Refurbished the handbrake from handle to compensator and refitted to car. Original cable in good nick.
12th August 2017
Loose fitted the steering rack, rear dampers, rear springs and rear radius arms, need to make up a couple of spring housing seals too, although these weren’t actually fitted to my car originally.
Fitted new rear brake cylinders to the rear backplates. The bodies on the new ones were bigger than the old ones, took a fair few clouts with the hide mallet to get them to slot in!
13th August 2017
Fitted rear axle. Did this on my own, using a couple of large blocks of wood in order that the spring hanger was just in line with the spring shackles, and anpther block to carry the weight of the prop shaft mount (levels it up). Found it easier to remove the radius arms from the body (that I had already fitted!), fix to the axle then fix to the body. Make sure all your shock absorber bolts have the heads facing out. Once in place then lots of tightening up all round on the springs, mounting plates, radius arms (with jacked up axle). Due to my Spax dampers, I had to apply weight to the car to get them to line up, with it being a bare shell, not enough by itself.
Then able to fit the handbrake compensator and the handbrake cable.

14th August 2017
Both front suspensions fitted today. No dramas, everything slipped into place nicely. Had to make up a spring compression tool (2 x 8 inch threaded rod, with nuts and washers and small sockets as spacers). Now suffering from RSI from all the turns on the spanner. Can’t release the wood blocks used to support the dampers as there does not seem to be enough weight on the shell. Hopefully once I get it on some wheels we can all sit on it and release them 😉
15th August 2017
Back on it’s wheels and with steering! Dug the wheels and tyres out from their outside (under cover) store where they had been for the last 15 years. They survived well, just needing a quick wire brushing and cleaning up. Put 20 lb/in into each, and they all still held air! The Michelin XZX tyres still have plenty of tread, but they are now getting on for 30 years old so will probably be a bit hard and weak. Popped them on the hubs, added wheelnuts and removed the jacks. Forgotten how low the car sits! Took yhe weight of me and daughter to release the wood block on the left, but even with me standing on the H frame in the engine bay and my son on the wing (combined weight of @ 160kg) the wood block on the other side wouldn’t budge. Took to it with a length of wood and a hammer which got it moving. Popped the damper rubber out on the way but I’ll get that back on later.
Refurbished the steering column with new paint to inner and outer column (note to self, be more patient, let the paint dry!), tracked down the mounting bracket and the concertina grommet rubber thingy, and refitted column and steering wheel (Must get a proper socket for that 1 1/4″ nut!) Have to do a proper alignment of the steering rack and column later. Put some old castellated nuts on the track rod ends to save the nyloc nuts for prime time.
Feels like a real car again!
9th September 2017
A couple of week as ago I spent the day finding and sorting all my boxes of MG Midget bits I had stored away for the last 10 years. This helped to define a shopping list! I also pulled together all the items that required wire brushing sanding rust curing and painting, plenty to keep me quiet, also have the exhaust three branch manifold and straight through piping to derust and add high temperature paint:
I also dug out the start motor and dynamo, and ran some power across them. Dynamo turned but start was dead as a door nail.
A very useful video for testing your dynamo is made by Moss USA.
The first part you can do off the car, but to check for a voltage supplied BY the dynamo, the second part (where he just slings a fan belt over the pulley), it needs to be spinning. If it is not on the car this can be achieved with an electric drill at 1000rpm, and an 11/16 socket and some suitable converters to attach to the drill. fortunately the dynamo spins in the same direction as the drill!
A helpful starter motor strip down video, although for a Bosch on later cars, just to support what is in the Haynes manual is here:
I got the starter motor in pieces, cleaned up the brushes and the commutator, checked that the field coils were delivering, as per Haynes, then put it all back together again. Ensure the terminal is not earthing against the backplate. Connected up to battery and away it went. Guess lack of use was the main cause of the problem.
Have decided to go all new with the brakes, so new pipework and connections, calipers, drums etc. Also bought some bonded nitrile cork to make up gaskets for things like the pedal box and cover
19th September 2017
A few bits arrived in the post. Fitted the check straps to the rear axle. The rest were mostly brake washers and screws. Not ready for that, but have 7m of cupro-nickel brake pipe to play with. I have a cool pipe flaring kit (see video below) which I used to make up all the pipes for my Range Rover, so should be a cinch on the MG. Got to figure out / remember the pipe runs for the front to back pipe and the clutch. easier when everything is in the way, e.g. engine, gearbox, ancillaries!
That photo of all the bits on 9th September, these have all been rubbed down, derusted, primed and painted now, some in a fetching “Halfords” Dark Green, which is quite bright, the rest in gloss black.
Pulled the petrol tank out of the loft and gave that the treatment:
Wire brush (hand held), wire brush on the drill, Kurusted, grey primer, whole can of black stone chip, dark blue top coat.
Also tested out the fuel gauge and sender unit, all working fine. Wiring confusing! Connect wire from lucar on the sneder unit to the “T” connection on the gauge. Connect the “B” connection on the gauge to +ve terminal on battery. Earth both the sender unit and the fuel gauge, and moving the float should show the gauge rise and fall. See pdf of writings by Dr Davies and others from MASCOT
Pipe Flaring Tool (enjoy groovy music!)
23rd / 24th September 2017
Wiper Motor and Wheelboxes
I have the Lucas DR3A wiper motor that lives in the engine bay and drives the two wipers, single speed. It was working before i took the car off the road, but like everything else needed a refurb after sitting for 20 years!
First thing to understand is the wiring, which is a bit odd. The unit has three terminals: 1, 2, and E. 1 is black/green wire on the car that runs to the wiper switch. 2 is the live feed and E is the Earth / ground. When testing off the car it is important to know this, and not think you have a two speed wiper unit. You do need to connect the two ground wires 1 and E for things to work properly.
Second thing to remember is that the DR3A has an adjustable limit switch cover. If your motor was working before you removed it from the car, or hasn’t been touched for donkeys years, it is best to mark the position of the limit switch cover again the main gearbox cover. There is a small projection (bump) on the cover you can use as a guide. Mine was just to the left of centre.
No dramas dismantling the motor, only real issue was with the motor brushes, which were worn right down to the holders. New brushes on order.
With the motor reassembled, and then wired up correctly to the battery, away it went
Both wheelboxes were nearly solid after no use and neglect. When removing both, remember which way round they fit. Take a photo! I didn’t, and had to dig out the fittings and trial fit, look up in manuals and parts catalogues for orientation. Anyway, a squirt of oil under each cog and some twisting and turning and pulling freed up the spindles and got them moving nicely. I removed the tubes and the drive line, cleaned these up, new grease and then all back together.
Heater Blower Motor
There is very little information about the actual blower motor, so this was a voyage of discovery. Removed the motor unit from the blower housing, and undid the “14mm” brass nut which held the fan onto the motor. I then tested the motor on a battery, it whirred away quite happily, but based upon the other motors thought it best to check out the innards. Should have left well alone!
Important! Undo the two nuts holding the through bolts in place, but do not remove the through bolts. The motor is covered by two casings, one at either end. Do not remove the casing with the wires coming out of it, but first remove the other end. This will allow you to see the way the motor is put together, especially the spacer and spring on the through bolts.
Important! Clean off the end of the armature where the fan was fitted. Clean it really well: metal file, wet and dry, wire brush, so that it will offer no resistance to the brass bush in the casing.
You have probably figured out that I did neither of these things, ending up with a collection of bits and pieces on the bench!
Because I didn’t clean off the end of the armature, when I pulled and (tapped away with a hammer) on the commutator to get it out, it forced the brass bush out of its spring loaded holder.
The holder had been pinch fitted, you could see four little clumps of metal from the outer casing holding the holder in place. I got out my dremel-like tool with a tungsten carbide tip and ground away at these little clumps. The with a small screwdriver working through the armature hole, tapped away at the holder. It eventually popped out! I put a couple of drops of oil on the felt at the end of each casing, popped the brass bush in, replaced the spring loader and holder, and tapped back into place with a screwdriver. Phew!
Final issue was to figure out the order of things for the spacers, springs and washers that fell out because I removed the through bolts. I went for spacer between field coils and brush housing, spring and washer between brush housing and casing. This seemed to work. This is why you take off the end without the wires first!
Brushes were in good order, so put everything back together, tested on battery again and it whirred away quite happily. With the fan on you get quite a force of air out of the thing.
Time to get setup to strip down the engine!
25th September 2017
Filled the rear axle with new 75w-90, and loose fitted the petrol tank (will have to come off to do the wiring) just gets it out of the way for now. 😉
26th September 2017
My overbored +60 1275 (1300!) engine has been languishing in a corner of the garage by the catflap for over a decade, oil drained and orifices plugged. Dragged it out to a more suitable position and gave it a good dust and vacuum down.
Started work on the back end, and thought I would see how seized the clutch was! The six bolts holding it on came undone easy enough, then it just fell off! Lots of wear left on the clutch plate, but I think I will get a new one anyway. So will the flywheel come off? Hell yeah! Six bolts undone after tapping back the flap washers, and judicious use of the hide hammer through the start motor ring saw this fall off too. So what about the endplate? Undid @ 9 bolts, hide hammer and off that came too. BTW, all bolts were screwed back in to their original locations for safekeeping. I am going to enjoy this, but need to set up a bench (or clear one of the two I already have) so I don’t have to do everything on the floor over the winter. Yes, the engine still turns.
1st October 2017
Fitted the new brushes to the wiper motor today. The new ones come with a serrated edge at one end, this goes against the commutator with the grooves vertical. My one is broken already, but it might make sense to remove the card/plastic holder for the brush mountings (under the commutator) as this could break when you pull back the brush mountings to insert the brushes. I used tweezers to hold the brushes with.
2nd October 2017
Took my head off and started refurbishing it today. Only item that fought was the thermostat housing, water pump, heater tap, all other nuts and bolts undid nicely. Got out some new nuts and ran these up and down all the threads using WD40, then did the double nut spanner trick and removed all the bolts from the head. Did the same with the head bolts in the engine block. These bolts and the push rods set in cardboard, numbered, and with “stat” written at one end!
Dug out the valve spring compressor and removed all the valves after a preliminary clean up on the combustion chambers. Quite a lot of crud on the exhaust valves. All a bit black and oily in the ports ? Then set about cleaning up the valves and posts with my dremel like tool and my trusty bone handled knife from the 1920’s (which I remember using last time I did the engine in the early 1980’s) a final clean off with a wire brush attachment on the drill. Checked out the bypass hose adaptor, this looked OK, but cleaned it up and kurusted it for good measure. Was tempted to go at it with a chisel and put a new one in, but didn’t want to risk failure at this stage.
Gave the head face a good rub down with some 800 wet and dry (using WD40), after cleaning up the rough spots with boned handled knife.
Tomorrow will lap the valves back in with coarse then fine paste, clean everything up and then reassemble.
3rd October 2017
As planned, valves all lapped and ground back into their seats and resprung. Renovated the thermostat housing, and dug out the new heater tap (word to the wise: a new tap does not necessarily come with the mounting and washer needed), and eventually found a new thermostat I had kicking about (82 degrees). Tested this and the one I took out (also 82 degrees) in a saucepan of boiling water, both opened OK, but it took boiling water to do it???
Cleaned up the head, wiped down with white spirit, dried off, then primed and painted up bright red! Thinking engine will be black , with ancillaries yellow/blue.

Main Engine Strip Down and Rebuild
I have been quite remiss, over the last couple of weeks, enjoying stripping down and rebuilding the engine block so much, not taken any photos! but will do so now it is mostly done.
Having torn down the back of the engine, and endplate off, I moved to the front. Drive shaft pulley bolt came undone with a decent whack on my 1930’s ring spanner, and managed to easy the pulley off with a little hide hammering and pulling. Timing cover all undid OK to reveal timing gears and chain. camshaft nut undid OK in similar fashion to above, and the gears levered off without too much trouble. Stripped out the rest and wrapped in paper.
Engine was light enough now to be manhandled by one, so cleared my outdoor undercover bench, and carried the engine out to it! Phew! I lay the engine on its side to remove the sump, as I didn’t want whatever had settled to go back into the engine. Sump off. Pulled out the camshaft, and removed the oil pump, cam followers (tappets) and then stood the engine on its head (so to speak). I have been using Haynes as a guide.
All parts and items were in fairly good nick. What followed was lots of cleaning, sanding off gasket surfaces, priming and painting, then slowly and carefully reassembled. Hopefully got the timing gears back in the right position, and set the distributor drive up on the cam. Didn’t go in the way Haynes said, but final alignment as per the picture. Fingers crossed! Also forgot to fold over the washer on the camshaft nut so had to have the timing cover off again to get that right. Engine has now got heavy, so will have to wait for No. 1 son to appear to give me a lift.
In the meantime been busy buying new bits. Decided to go for an all new clutch, found a good deal online for a Borg and Beck clutch housing, plate and release bearing. My existing one looks OK, including clutch plate, but would rather stick new in to save engine out issues! Bought a halogen light conversion set, along with some relays (do not want to frazzle my new loom!), new cooling hoses, new rear brake drums, fuel/brake pipe clips, dizzy cap and new leads.

Moved the engine and gearbox back into the garage, and stored under mildy oily towels, awaiting the arrival of the engine hoist. Fitted the flywheel just as the delivery guy appeared with the new clutch set, so fitted that too. Table now clear so may have a go at stripping the dash. Will need photos for this!
