14. BSA A10 Top Gear

Having assemble the BSA A10 gear box, it is now time for a final polish and fitting the gearbox into the frame. Handling the gearbox for polishing when assembled is difficult because it is so heavy, which is why I stripped it in the first place. However it was well worthwhile as the reassembly process had left it looking a bit dull and it was good to polish where the three casing parts come together to give a nice nice finished look.

Fitting the gearbox required the removal of the right hand engine mounting plate. This was no problem as the left hand plate and the front mountings held the engine in place with no problems. The gearbox could then be passed through from right to left, followed by the right hand engine mounting plate and the two gearbox upper mounting plates. I passed the bottom gearbox pivot stud through the engine mounting plates and put the nuts on loosely. No point in tightening them as the gearbox has to pivot when adjusting the primary drive chain, which I'll cover later. The top adjustable gearbox fixing bolt, and adjusting mechanism was then fitted again loosely and then all of the engine and gearbox mounting studs and nuts could be tightened apart from the top two gearbox mounting plate nuts which need to be left loose to accept the Ski-slope that hooks over them and the battery tray.

You will notice from the photos that the clutch lever is not fitted at this point. Firstly because it has not arrived back from the chrome platers yet and secondly because I felt that it was best set up once the clutch was in place, which has yet to be fitted.

The gearbox is in, and looks excellent. BSA experts may notice, if you look carefully at the photo above, that something is missing from the inner timing cover, to the right of the picture. This will come back to bite me later!!
