3.3.8. REAR AXLE BEARING - LUBRICATION
1. The left rear axle bearing on 28” and 30”
machines requires three shots of general purpose
grease from grease gun. See Figure 3.7.
NOTE: Some models are equipped with a pre-
lubricated sealed bearing and require no additional
lubrication.
2. The right rear axle bearing is lubricated by the
differential lubricant and requires no grease.

3.3.9. DIFFERENTIAL/CHAIN CASE - LUBRICATION
1. Stand rear engine rider on its rear bumper and
check the fill/level plug, for cracks and wear. Replace
fill/level plug if signs of wear are visible.
IMPORTANT: If the Rear Engine Rider will be on its
rear bumper for longer than two hours, remove the
battery. Refer to Section “BATTERY REMOVAL”.
2. To check lubricant, remove fill/level plug and
visually inspect for lubricant on the internal parts of the
differential. If no lubricant is visible on the internal
parts of the differential, add transmission grease as
needed. See Figure 3.8.
IMPORTANT: Overfilling of the differential with lubricant will
cause lubricant to leak onto drive components of the Rear
Engine Rider.
