20. Lubrication for normal operation.
a. All intervals for lubrication are given in operating hours. For abnormal conditions or
activities, adjust the intervals.
b. When lubricating the equipment, take care to prevent oil or grease from getting into
the brake mechanism. Wipe off all excess grease around the axle shaft bearing. The excess
grease might work into the brake during operation. If oil or grease gets in the brake
mechanism, remove the screws that hold the brake unit together, disassemble the unit, wash
all parts thoroughly with cleaning compound, wipe with a dry cloth, and reassemble.
c. Lubricate the axle shaft bearings of the frame as follows (see Figure 45):
After every 8 hours, open the bearing caps and generously apply GAA. Close
the bearing caps and remove excess grease.
After every 40 hours, remove the axle, wash the axle shaft bearings with cleaning
compound, dry thoroughly with a cloth, and apply grease generously.
