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. 21)
.
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. 21)
. 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. 22)
. 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. 22)
. There is a spacer left on the motor that is not required to be removed. If spacer is
removed, reassemble per exploded view,
(Fig. 22)
.
* 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. 23)
. 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. 22)
.
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.
