Andy thanks for your reply, I will try and explain my problem. I have a 2wd saff this has a 4x4 crank fitted to it. I was told that the 4x4 ran with a multi groove belt so to use the 2wd crank pulley. The 4x4 crank has a bigger shaft than the 2wd but the 2wd pulley will go on but will be tight. The problem I have now is how hard to get the pulley of is, that's why I have thought about putting on a 4x4 pulley now. Will the 4x4 V belt be ok on a 2wd set up? Ie the four pick points.
Cheers
Paul
