  • 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 easily and inexpensively as possible.
