6.9 Rotary Air Blower
A good maintenance program will add years of service to your blower
Bearing Lubrication
Lubricate the drive end bearings every 40 hours of operation. Use NLGI #2 petroleum-based
grease with high temperature resistance and good mechanical stability. Use a pressure gun to force
new grease into each bearing until traces of clean grease come out of the relief fittings.
CAUTION
Do not inject grease too fast to avoid blowing out the drive shaft seal.
Oil service
Check and maintain oil level and add oil as necessary. Drain and refill oil after the first 100 hours of
operation and thereafter every 1000 hours, or more frequently depending on the type of oil and
operating temperature.
Oil capacity for the blower is 0.045 gallon (0.17 liters).
V-Belts
Re-tension belts after the first 8 hours of operation and check tension every 40 hours thereafter. To
check tension, place a straight edge across the belt span. Using a belt tension checker, push the
belt down midway between the pulleys and measure the deflection. Recommended deflection is ¼
inch with a 6lb force applied.
Inspect the belts regularly for signs of cracking or fraying. Replace the belts if they are showing
signs of wear. If one belt is showing signs of wear, replace all the belts together.
CAUTION
Over tightening the belts will cause shortened belt life and bearing failure of the blower and/or
engine. Do not use belt dressing on the V-belts. Keep sheaves and V-belts free of oil and grease.
Storing Procedures
If the machine is to remain inactive for extended periods of time, the unit should be stored in a dry
place. Protect the blower from corrosion; spray the interior of the blower (lobes, housing, and end
plates) with a rust preventative such as WD-40 to keep the blower from freezing up do to rust. If
possible, cap off the openings from air and moisture.
Remove tension from the drive belts.
When putting the machine back into service; spray the interior with penetrating oil and rotate the
drive shaft by hand to make sure the lobes will turn freely.
Re-tension the belts to the recommended tension. See section 6.9.3
