Lubricating Process
Remove either the louver assembly or the rear plate from the rear of the generator housing.
Remove the top grease pipe plug and remove the lower grease pipe plug.
Install a grease fitting in the grease pipe.
Grease the shielded ball bearings with 2S-3230 Bearing Lubricant ( 53.28 mL (1.8 ounces) to 59.20 mL (2.0 ounces)). Lubricate shielded ball bearings at 2000 hour intervals. Do not mix greases. Note: Some two-bearing generators have spherical roller bearings in the front bracket and ball bearings in the rear bracket. These units should use a common 108-8611 Grease Cartridge. This grease should be used for the front bearing and the rear bearing.
Wipe off the excess grease. Remove the top grease fitting. Install the plug.
Operate the generator for one hour. This will allow the grease to expand. The expanding grease will force the excess grease from the cavity. When the excess grease is forced from the cavity, the internal pressure will be reduced. The generator should continue to operate until the grease stops purging.
Stop the engine. Install the plug in the bottom grease pipe. Wipe off the excess grease.
Install the louver assembly or install the rear plate.
