Gearbox and Bell Housing

Here is the Type-9 gearbox and bell housing as bought secondhand from ebay.

Before separating the the two the clutch release fork was removed.  To do so required that the clutch release bearing be removed.  The bearing was destroyed during the process.  No problem as a new one is provided in the new Pinto clutch kit.  Once the gearbox and bell housing were separated they cleaned with lots of rags and lots of white spirit.

I attempted to remove the reverse stop from the gearbox, but in the end I gave up as it did not seem to want to move and I did not want to damage the gearbox housing.  I tried my Rally Design remote and it functions fine with the original reverse stop still in place in the gearbox.  There is a replacement reverse stop in the gear lever end of the remote.

Bell housing cleaned and degreased, ready for painting with Hammerite.

The oil seals on the input and output shafts were replaced.  The sleeve for the clutch release bearing has to be removed to change the input shaft oil seal.  Upon refitting a new cork gasket is fitted.

Here is the gearbox, repainted, with new oil seals.  The only oil seal that I could not change was the one on the speedo drive shaft.  I removed the side access plate, but when I looked inside you can removed the speedo drive shaft, but it looks like you can't get to the oil seal on the other side without completely dismantling the gearbox.  Something I don't plan on doing!  Fingers crossed this tiny oil seal doesn't let me down once the gearbox is in the car.

A new gasket was fitted between gearbox and bell housing prior to mating the two.  If this is not done the gearbox will empty its oil via the hole that the gear selector rod exits through.

Gearbox and bell housing bolted back together, torqued up as per the Hayne's manual.  The clutch release fork will be reinstalled, along with the new clutch release bearing, at a later stage.

New gearbox mount was trial fitted prior to putting the whole assembly aside, to wait for the engine to be tidied up.
