teeth

[les]

Anyone know the number of teeth on 1st--2nd--3rd and 4th gear of a mg1275 gearbox, please?

I think that I have a few missing on 1st

Same number as on a 1098 gearbox......... The difference (ratio wise) is in the Laygear.

I have found some answers having just stripped an mg gearbox, so if anyone is in need of information regarding teeth, laygear numbers etc-----I shoud be able to help! btw Roy, it appears that the some of the actual gearwheels do differ.

Welllllll - publish up what you have found !

Roy, I thought I'd just inform folk that I have info if required, rather than list stuff that may have a limited appeal, this being based on the number of posts enquiring about gearbox rebuilds in the past.

PM sent!

Post it anyway, it may turn out to be exactly what someone needs & you may not be around to send the PM ;)

Ok, I have no problem with that, but as it's quite a list, didn't want to do it if no interest.
