EZ GO rear differential question

wamp98 · 03-28-2009, 02:12 PM

Hello to all. I am building my first cart, and have run into a snag hoping all you experts can help. I have an ezgo gas cart that I have installed a 440 snowmobile engine in. I have the motor alligned, and am using the stock snowmobile clutch on the crankshaft. The differential is marked ME29. In order to make the cart go forward, the lever has to be in reverse. Will this differential work that way? Also, it seems that I am getting very little speed at the rear wheels in both forward and reverse. The motor revs fine, and the pulley on the axle spins like crazy, but the tires are not moving very fast. What does the small shaft coming out of the top of the differential do? Is this a high/low, or neutral, or what? It won't turn or shift at all? Any help will be great!

Hello wamp98 and Welcome to the forum.

I have to agree about getting pics of it, never heard of anyone who has done similar swaps having to run the rear in reverse on an ezgo. on some club cars you have to do that

The speed issue could be a belt thats to long. most carts with sled engines will fly.

It sounds like the snowmobile engine is turning the opposite way, They is why you need reverse to go forward. When I 1st put my Ski Doo engine in my Marathon I didn't have any power. I used a muffler off a motorcycle. I put the ski doo muffler on & had lots of power

yep, the muffler/chamber is a big deal with 2cycles

Sorry guys for the delay, pics are on the way. Thanks much for the info about the governer shaft. That's a relief. I have not actually drove this yet to actually say that it is slow, but while up on jack stands, and the tires just didn't rotate very fast. The belt tension is one of the issues that I am trying to figure out. The motor mounts I fabricated allow for alot of adjustment in the tension, so I can keep trying till I get it right.

Ok, so I know I am failing you on the pics, but should have some here tonight of the build. I have been checking the threads, and see some people are removing the governor shaft from the differential. Is this for speed/torque, or just to get unnecessary parts out of the way. Another question is how difficult is it to weld the spider gears in the rear end to get rid of the one-wheel-peel. I have put the "Lincoln Lockers" in trucks before, but never messed with the cart diff. Has anyone done this, and any luck? Thanks!

They have been known to fly apart for excessive RPMs and cause damage to case or gears

Yes, people do it all the time. Inside the case it's (the carrier) more or less the same as a truck would be only smaller
