SECTION 3
LUBRICATION
FIGURE3-
1
- LUBRICATION
At the gear end the timing gear teeth are lubricated by being partially submerged in oil. The gear teeth serve as
oil slingers for gear end bearings. At the drive end the bearings are grease lubricated.
FILLING PROCEDURE
Refer to Figure 3-1. Remove the breather (B) from the gear cover. Add oil to the gear case until it reaches the
center line of the oil level gauge (H). Secure breather (B) in its correct location.
LUBRICATION SERVICE
Add fresh oil as required to maintain proper level. The oil should be drained, flushed and replaced every 1500
hours or more frequently if inspection so indicates. The oil drain plug is located at (A).
Do not overfill as this will tend to cause excessive heating of the gears and may damage the unit.
Bearings on the drive end of the blower require grease lubrication every 500 hours of operation. Lubricate the
bearings through grease fitting located at (C). When regreasing, the old grease will be forced out of the vents (E).
To prevent damage to seals, these vents must be open at all times.
AIR FILTERS AND FILTER SILENCERS
Servicing the air filters is one of the most important maintenance operations to be preformed to
insure long blower life.
Servicing frequency of filter elements is not time predictable. A differential pressure indicator, with a continuous
gauge reading, should be installed across the inlet filter. It will tell how much of the service life of the filter
element has been used. It will also eliminate both premature filter servicing and premature blower failure due to a
plugged filter when the filter pressure drop is used to establish maintenance points. In all cases refer to the filter
manufacturer
’s service instructions. Due to the many types of filters, it is not practical to give specific instructions
covering all models.
NOTICE
Do not overfill as this will tend to cause excessive heating of the gears and may damage the unit.
