Hi guys, anyone got a spare gearbox kicking about?

I am not sure about my skills as far as gear box repair is concerned.
The aircooled is now running and better than I could have dreamed but first movement was a bit of a disapointment as it jumps violently out of first gear and every other gear is noisy.

Bis box should do ok I think.

bis box will do but you will have to change the bell housing...........easy but you might as well do your box........ :cool: ...pm if you want any help

did'nt realise the bis box would fit an aircooled.......My scrapper was just about to leave for the yard.....I'll pull the geabox first.

yep Ger,just change the bell housing,all you need is a gasket set,and its a good idea to do the input shaft seal at the same time.....once all done you then get the taller gearing off the bis as well!

a new filler plug doesnt go amiss either :wink:

I'm going to have a 650 in my 500, would you advise the BIS box or the standard 650 box??

well,i reckon a well set up 650 is cpable of pullng the extra gearing,i have built such a box for mine and will be fitting it to the new car im working on at the moment.

paul harbinson fitted one i think in his mates 126...
