The basics…

The 4wd system on your Yamaha ATV or Side by Side is operated by a push button switch that sends power to a relay, which in turn sends power to the servo motor, which engages your 2wd, 4wd, and difflock.  It’s easy to troubleshoot and repair these components without spending an arm and a leg.

If you are unfamiliar with the 4wd system, see our troubleshooting page.  It will help you identify, diagnose, and repair your 4wd issues as easy and inexpensive as possible.

    I was pleased with my experience dealing with 501 parts. The part arrived much quicker than I thought it was going to and was exactly as described. I was able to get it installed easily with help from the YouTube videos and got my atv working again. I would gladly purchase from 501 again.
