Spitfire gearbox prep

Started to prepare the transmission while the engine was being machined.

Peeked inside and it doesn't look too bad. Apart from quite a bit of metal particles collected on the magnet. Will probably need to revisit later for synchros...



Wanted to replace the seals so that at least it doesn't leak on the garage floor. Had to remove the flange for the rear one. Had to use the usual amount of penetrating oil + heat + impact gun.
See my "red neck" technique for locking the flange into place. 


Once removed, pulled out the old seal and pushed new one in with a large socket.


I was surprised to hear there is no seal at the front on these ones, just a screw type mechanism to push the oil away. So don't park your car nose down on a hill !

Used the clutch fork that had the least amount of play and fitted the new clutch bearing.


My technique for removing the old bearing. It's simply pushed in.


Final result, I have to admit the biggest pain was cleaning and painting the bellhousing. 30 years of oil took a while to clean. Hence my obsession with seals, the new one has to remain clean !
