Once the engine was off the engine stand and hanging on the hoist, I could install a new pilot bearing, the flywheel, and the clutch.

These pictures illustrate some of what is involved in rebuilding the MGA gearbox. All parts except the gears were renewed.
It looked to be a formidable task at the beginning. But once you get into it everything makes sense. I assembled and reassembled it so many times, checking out clearances, etc. that I think I could now do it blindfolded.
Must have been hard shifting with this mess in the shift lever.
The ball bearings on the input shaft and mainshaft were replaced with new. The lay shaft and needle bearings were replaced. The layshaft and mainshaft thrust washers were replaced. All seals including the speedometer drive seal were replaced. Rusted parts were sandblasted, everything else was cleaned in solvent.

As a start to rebuilding the gearbox I did the clutch slave cylinder and throwout fork first. As usual, everything was dirty, worn out, and seized.
Notice the wear in in the following picture in the old clevis pin and clutch fork pushrod. These were fixed with new parts. The clevis pin end of the clutch fork was also worn to an oval. This is a 5/16" hole but was badly oval. I drilled it out to 3/8" and then pressed in a 3/8" OD X 5/16" ID bushing, good as new.

Many British Cars are equipped with SU carburetors as is my MGA. This series of photographs shows some of the steps involved in rebuilding these carburetors. In the following photo, note the yellow arrow. This is pointing to the carburetor's fuel bowl vent/overflow pipes. If the fuel bowl overflows, which it sometimes does, then these small pipes are to drain the raw fuel safely onto the ground. However, some idiot has cut them off so that raw fuel will drain directly onto the very hot exhaust manifold. Naturaly I had to correct this mess.
This is what is inside. These are the old parts most of which were replaced with new parts.
These are all of the old parts cleaned and all of the new parts. Now, if I can just get everything back where it belongs.
Well, everything seems to fit OK. Note the repaired fuel vent/overflow pipe.
