I have a 1275 pre-A+ engine but with the big 2" crankshaft and primary gear (Originally from Allegro). The gearbox is a 22G1832 so it has the pre-A+ 1275GT gear ratio with the small idler bearing. My gearbox casing is damaged with stripped threads and possibly some cracks. I have the option of buying a good DAM5626 empty casing and was wondering what parts I can re-use and what other parts I would need to purchase.
I assume I can use the diff/FD (I already have a new 3.44FD ratio to put in the diff). Can I use all the gears but with a new layshaft and bearings? Or do I need all new gears. Because the engine has the bigger crank and primary gear will this mate to an A+ gearbox idler gear?
Essentially it's an economic exercise to see if it's worth it; If I need to buy too many parts I'd have to look at another option. The DAM5626 casing itself is pretty expensive. Or if it ends up being too expensive to switch everything over does anyone have a reconditioned DAM5626 they could send to NZ?
