Speed Increase
Close the pulley in order that the belt rides higher in the
groove (larger pitch diameter). Ensure that the RPM limits
of the fan and the horsepower limits of the motor are
maintained.

Pulley and Belt Replacement
1.
Clean the motor and fan shafts.
2.
Loosen the motor plate mounting bolts to relieve
the belt tension. Remove the belt.
3.
Loosen the pulley setscrews and remove the
pulleys from the shaft. NOTICE! If excessive force
is required to remove the pulleys, a three-
jaw puller can be used. This tool, however,
can easily warp a pulley. If the puller is used,
inspect the trueness of the pulley after it is
removed from the shaft. The pulley will need
replacement if it is more than 0.020 inch out of
true.
4.
Clean the bores of the pulleys and place a light
coat of oil on the bores.
5.
Remove grease, rust and burrs from the shaft.
6.
Place fan pulley on the fan shaft and the motor
pulley on the motor shaft. Damage to the pulleys
can occur when excessive force is used in placing
the pulleys on their respective shafts.
7.
After the pulleys have been correctly placed back
onto their shafts, tighten the pulley setscrews.
8.
Install the belts on the pulleys. Align and adjust the
belts to the proper tension as described in Belt and
Pulley Installation, page 2
Bearing Replacement
The fan bearings are pillow block ball bearings.
1.
Mark the position of the shaft in reference to both
the bearing races and the propeller and pulley.
Make a note of the clearance between the propeller
and the frame.
2.
Remove the pulley.
3.
Remove the propeller from the shaft. A two-jaw
puller may be needed to remove the propeller from
the shaft.
4.
Remove the bearing hold-down bolts. Remove the
shaft and the bearings as one unit.
5.
Remove the anti-corrosion coating from the shaft
with a suitable degreaser.
6.
Remove the bearing from the shaft using a bearing
puller. If a bearing puller is not available, remove
the bearing by using a wood block and hammer.
An emery cloth or file may be needed to remove
imperfections in the shaft left by the setscrews.
7.
Clean the shaft and bearing bore thoroughly.
8.
Place the bearings into position ensuring they are
not on a worn section of the shaft. Tapping the
