Review the safety section of this manual before attempting
these procedures.
Removing Drive Bearings (refer to 5.3a thur 5.3d):
1. Remove the impeller and drive belt as described in this
manual.
2. If the bearings have not "seized" onto the shaft then re -
moval is straightforward.
3. Loosen the pulley (item# 2, fig. 5.3a) by removing the
bushing bolts (item# 3, fig. 5.3a).
4. Remove the bearing collar (Item# 3, fig. 5.3b), if equipped,
at the rear of the front bearing (the bearing closest to the
blower housing).
5. On the rear bearing (closest to the engine) loosen the set
screw on the bearing lock collar (Item# 1, fig. 5.3b)
6. Pull the shaft out toward the blower housing. The bearing
plate, front bearing and pulley should come out in one unit.
7. If the shaft doesn't pull out easily, lubricate the shaft gen-
erously where the shaft goes through the bearings. If the
shaft still doesn't come out, the final solution is to cut the
shaft in half.
8. Once the shaft is out, remove the front bearing from the
shaft by using steps 5 and 6.
