Differential gear oil

The differential gear case must be checked for oil
leakage before each ride. If any leakage is found,
have a Yamaha dealer check and repair the ATV.
In addition, the differential gear oil level must be
checked and the oil changed as follows at the in-
tervals specified in the periodic maintenance and
lubrication chart.
To check the differential gear oil level
1. Place the ATV on a level surface.
2. Remove the differential gear oil filler bolt and
its gasket, and then check the oil level in the
differential gear case. The oil level should be
at the brim of the filler hole.
