3. Flip the bearing housing over and detach the
brake arm from the brake assembly and the
brake actuator (Figure 40).
4. Pull the belt off the pulley (Figure 40).
5. Slide the Wagner Anti-Wrap bracket off the
bearing housing. You may need to tap it to
make it slide off.
6. Remove the brake assembly and spring from
the bearing housing (Figure 41).
7. To remove the pulley (Figure 42), unscrew the
set screw from the pulley with an Allen
wrench. Then tap the pulley to loosen it from
the shaft. Be careful not to hit the shaft, as it
will expand and make the pulley harder to remove. Remove the pulley. You may need a pulley
extractor.
To Mount the New Bearing Housing
1. On the new bearing housing (Figure 43), mount the pulley and key (Figure 42), leaving the shaft
recessed about 1/16", and secure with the set screw. You may want to use Loctite
®
242 to keep
the set screw in place.
2. Mount the brake assembly and spring (Figure 41).
3. With the bearing housing upside down, attach the brake arm to the brake assembly and the brake
actuator (Figure 40).
4. Mount the belt around the bearing housing pulley (Figure 40). Be sure the belt is placed on the
INSIDE of the belt guides (Figure 46)and that the other end of the belt goes through the belt
retainer and around the engine pulley. Also, be sure the belt is on the INSIDE of the idler pulley
#1 (Figure 44).
