The thrower seems to work good, so I put the flywheel back on. The clutch lining was full of oil and grease, so I tried to wash that out as best I could with brake cleaner.
The big project was creating the new push rod. My workmate Mike had already made the pushrod receiver that I tack welded to the square hole in the pressure plate. I wanted to make sure it wasn't going to come out and get jammed in the shaft somehow, hence the tack weld. It shouldn't, but I didn't want to chance it, and I didn't want it to start turning either, since the shaft into the pressure plate is round instead of square.
I took Wilhelm's full length measurement (225mm) from the surface of the pressure plate to the end of the rod and cut the 1/4" drill rod that had bought to fit. I squared up the ends in the lathe, gave them a slight chamfer and then polished them up to a high shine. Drill rod (aka silver steel) is fairly hard so that took a while. I test fit it in the gearbox and it looks right. I can drop the rod in after the gearbox is mated to the engine.
I decieded against a ball bearing at the clutch end for now. I can always cut the drill rod more and fit the ball bearing later if I think its not working right.
The next fun part will be to compress the clutch springs enough to put the nuts on. I guess a few clamps around the flywheel and pressure plate may do the trick?
