porkhaaks · Dec 7, 2010

Has this been asked or point me to the answer please !!! so the question.. Is it possible to change extro drivers on a stock shaft from 252 pitch to 3 pitch? This is so I can run a 154" track possibly on a 2001 MM700. ANY ideas will help... THANKS in advance porkhaaks...

Yes it is. If you have 8 tooth 2.52 you will need to go to 7 tooth 3 pitch. In this case the 7 tooth will be a bit bigger than your 8 tooth.

That post of mine explains why they are bigger.

yep, as mentioned above - just do the math to get the desired final drive ratio
