Motor
Under normal usage, the drip proof style motor will require that
you add 3-4 drops of SAE 10 motor oil to each oil port on the
motor after 25,000 hours of operation. Should your blower motor
experience constant use, maintenance should be on an annual
basis, to extend the life of the blower motor.
Bearings
The pillow block bearings on your blower are factory sealed and
lubricated. Under normal operation, no further lubrication is
required. Excessive lubricating may cause damage to the bearing
seal and significantly shorten the life span of the bearing.
V-Belt
The drive belt on the blower should be inspected on a monthly
basis for excessive wear. Fraying of the belt would indicate
possible misalignment of the blower’s sheaves.
The gravity belt tightener, incorporated into your blower assembly,
extend the life of the V-belt if properly adjusted. If you need to
replace the belt, remove the upper weathercover and lift up on the
motor. The belt should be replaced a minimum of once every four
years.

Replacement Parts)
Pillow Block Bearing Replacement
If you need to replace a pillow block bearing on your blower, make
sure that the locking collars on the bearings face one another. The
setscrews used on the locking collars have been sealed with a
removable thread sealant. Thread sealant should be applied when
a pillow block bearing is replaced in the field.
