Repair Help

Hello guys and gals!

I recently bought an immaculate 1985 Big Red 250 es. The problem is that the rear diff is ruined.

I’ve been working on ATV and Motorcycles for a long time, but never have I cracked a differential open. To be honest, I’ve never had a problem with any diffs in 35 years.

How difficult of a job is this to take apart? should I just look for a second hand rear diff? Is there a rebuild kit for the rear diff? Are there other models that fit the Big Red? I’m desperate because I absolutely love this ATC!

Does anybody have some excellent links for used ATC parts stores?

Thanks for any replies!

Adam
