How to Change the Rear End Grease on a Yamaha Grizzly 600

14

The rear drive shaft and final drive system used to power the rear wheels on your Yamaha Grizzly 600 ATV rely heavily on gear oil to supply the lubrication they need to operate properly. An insufficient supply of gear oil can cause your Grizzly to overheat, as the motor must work harder to turn the rear wheels. If left unchanged for too long, the gear oil will degrade completely, allowing friction to cause permanent damage to the final drive. At a minimum, the rear end’s gear oil should be changed annually. This task can be completed in less than 30 minutes.

Tools Used: Tools, 21 mm socket, Oil pan, Socket wrench, 6 mm Allen wrench, Shop towel, Funnel, 1 qt. SAE 80 API GL-4 hypoid gear oil

Change the Rear End Grease

Unscrew the filler bolt from the top left side of the drive shaft housing, using a 21 mm socket and a socket wrench. This will vent the housing and allow the oil to drain easier.
