M151 Gearing.

Unread post by k8icu » January 21st, 2008, 11:40 pm

This got asked over on SS so I thought I'd post it here because well my manuals are packed in my garage and its freeking cold here and I wont get to them till May.... :)

So anyone got an answer for me?


"What is the gear ratio of the M151?
What are the gear options and what is required to change the gearing?
The lower the better as it will only bused off road going up and down a mountain for hunting, hauling corn, etc."

Of course we all know what a granny gear 1st is. IMHO that's all he will need, but some people I guess love to tinker.
There is one nut on a M151 that is very difficult to remove.....
