H. OIL LEVEL GAUGE
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. 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 fittings 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.
