Yamaha Big Bear 350 Restoration! Part 3! 

Thanks for the pictures. That was key. I had to do one of these a while back and could not find any video on the process. Nice work.

Weld a washer to race and use a Inner Blind Hole Bearing Puller Set Internal Remover Slide Hammer. Works and you don't mar up the swing arm. Puller is cheap.

I just inherited a 1989 big bear from a family friend. It’s a blast to ride, but I have a weird crunching/groaning sound coming from the rear end that I’ve yet to diagnose. Where do you get your original Yamaha parts from? Also, where would I find the specs for setting backlash on the diff, torque specs, etc? Thank you

I am about to embark on a similar mission. I acquired a 1998 Big Bear 350 from a coworker for $150, it was not running and needed a considerable amount of work, it now runs and I have most of the work done now I just need to tackle the rear drive seals as its leaking motor oil right down through the swing arm, into the rear diff and out the axle seal.... are you able to provide me with dimensions or a photo of that socket? Thanks again!

How complicated and how long does it take to do this job?! I have a 95 kodiak 400 4x4 that I'm gonna have to do this same thing too!! Tia
