8. Caterpillar SR4B: Maintenance Interval Schedule (Standard) (Every 2000 Service Hours)

Bearing Ball Lubricate

The following ball bearings must be lubricated: no shield and single shield. Double shielded ball bearings may not require lubrication. Refer to the grease plate instructions that are located on the machine.

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.
Grease spherical roller bearings with a 108-8611 Grease Cartridge (29.6 ml (1 ounce). Spherical roller bearings should be lubricated at 1000 hour intervals. Do not mix greases.
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 of the grease pipe. Wipe off the excess grease.
Install the louver assembly or install the rear plate.
