MOTOR FAN REPLACEMENT
Removal
1. Mark the position of the fan case's location on the motor with a pencil, or score
it with a sharp object before disassembly. This will aid you in reassembling the
fan case, (Fig. 18).
2. The fan case has three (3) crimped sections on it to hold the case onto the
motor. These will have to be straightened by using a pair of needle nose pliers
and by tapping out on the crimp area with a flat blade screwdriver. Be sure
and straighten all three (3) crimped areas, (Fig. 18). Remove the fan case from
the motor unit.
3. Tools required to remove the fan from the shaft will be a 1/8 - inch Allen wrench,
a 1/2 -inch offset box wrench, torque wrench, and a hammer.
NOTE: Be careful when handling the sheet metal parts as there could be sharp
edges. Do not scratch or bend the motor shaft. Scratches will cause belt
breakage during operation.
4. Place the 1/2 - inch box wrench over the 1/2 -inch hex nut that holds the fan onto
the motor shaft, (Fig.19). While holding the wrench on the nut, place the 1/8 -inch
Allen wrench into the end of the motor shaft and loosen the nut while holding the Allen
wrench still. The nut will have to be turned clockwise as it is a left-hand thread. After
removing the nut, remove the fan, (Fig. 19). There is a spacer left on the motor that is
not required to be removed. If spacer is removed, reassemble per exploded view, (Fig.
18).
* Some models will have this washer and spacer.
Installation
1. Place the new fan onto the motor shaft, making sure that the
spacer is still on the motor. The large diameter hole, approximately
1 1/8 inch, will be on the top of the fan as you install it.
2. Install the flat washer with the burr side of the washer
facing away from the fan, (Fig. 21). Screw the nut onto the motor
shaft, turning it counterclockwise, left-hand threads, and torque to
20-30-inch pounds. Be sure to hold the motor shaft by placing the
1/8-inch allen wrench into the motor shaft end while torquing the
nut, (Fig. 19).
3. Align your marks on the fan case as you put the fan case back
on and tap around the case uniformly. Tap the three (3) crimped
areas over and then use a flat blade screwdriver to recrimp them.
4. See (Fig. 20) for reassembly specifications.
Use these specifications
to assure that the fan
case has been tapped
back to the original position.
These measurements
4.2"/4.5"
are approximate.
