Limited slip diff Marathon
Now that I have built my cart nasty enough to really get back in the woods I am getting stuck in mud too much, time to work on the rear end and stop the one wheel spin open diff issues.
In researching I cant find a LSD conversion for the Marathon rear end, I even went so far as to contact the people who were issued the patent for the kits that everyone is selling for later models, no joy. I read some posts here from a few years ago where a member was talking about packing the spider gears...did anyone ever try this? http://www.buggiesgonewild.com/elect...tial-lock.html Quote:

Re: Limited slip diff Marathon
I put a RXV posi diff in my marathon, no problem. You can use all your stock gears (about 12.5):1, or (carefully) mix and match rxv ring gear and intermediate shaft like i did to achieve a roughly 14.5:1 ratio.

Re: Limited slip diff Marathon
I don't much about different kinds of carts. How "posi" is the RXV diff? Is a true LSD with clutch pacs? Did you just swap out the carrier or the entire rear end?

Re: Limited slip diff Marathon
It is a true "clutch type" posi. I used the carrier, ring gear, and intermediate shaft from rxv. I used the input shaft and second gear for the intermediate shaft from the marathon. you could use all of your stock gears including the stock marathon ring gear on the RXV carrier. if you use an RXV intermediate shaft you have to substitute a different bearing for the intermediate shaft (i think it was a 6204). These parts all went into the marathon axle housing. I went the way i did because im going with bigger tires, and wanted to get a better ratio for climbing power. I can't say exactly how well it will work because the project is not finished yet but everything went into the axle just fine

Re: Limited slip diff Marathon
What year is the carrier you used from? Did they put these posi carriers in from like 94-97 only? Or did it come out of some special workhorse type cart?
I ask this because Marathons are open diffs and there is an aftermarket LSD kit for 98-06... |

Re: Limited slip diff Marathon
Ive got more welding to do. Not done yet. But the axle went together just fine (its assembled & waiting for the frame to be finished). I gotta get a shield gas regulator for my welder. So many "unexpected projects -ie Keep everyones autos running" projects i dont progress fast at all. Hey, i want at least one day a week to "kick back & relax, maybe watch a football game". I was changing spark plugs at halftime during the Steelers/Denver game. Boo Denver!

Re: Limited slip diff Marathon
How did this LSD conversion work out? I'm looking to do something like this to my 92 Marathon.
