WARNING 
DO NOT attempt any adjustments, maintenance, 
service or repairs with the engine running. Stop 
engine. Stop blade. Engage parking brake. Remove 
key. Remove spark plug wire from spark plug and 
secure away from plug. Engine and components are 
HOT. Avoid serious burns, allow all parts to cool 
before working on machine. Fuel Filler Cap and Vent 
must be closed securely to prevent fuel spillage. 
 
3.3.8.  REAR AXLE BEARING - LUBRICATION 
1.  The left rear axle bearing requires three shots of 
general purpose grease from a 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 “SNAPPER 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.
