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.

    Great kit to repair your 4wd system. I didn’t want to troubleshoot the system, I had a ride the following weekend. I bought this kit and it fixed my problem! Thanks 501 Parts!
