Replacing the Sheave On the Sheave Shaft
Look at the key slot on the sheave assembly. The length of shaft to the right of the key slot is
longer that the length of shaft to the left of the key slot. When you slide the sheave onto the shaft,
make sure that the sheave hub faces the left end of the shaft.
13. Position the key in the key slot in the sheave shaft. Push the sheave shaft through the
sheave so that the key is centered on the key slot in the sheave.
Note:
When you slide the sheave onto the shaft, make sure that the sheave hub faces the left end of
the shaft.
Replacing the Bearing On the Sheave Shaft
14. Slide the two flanges and a bearing onto one end of the shaft. A flange must be on each
side of the bearing as seen in Diagram 7.16. The flange shoulders must face away from the
bearing. If you are replacing both bearings, repeat this step for the second bearing.
Replacing the Sheave Assembly
When you install the sheave assembly, the hub must be on the left side of the climber.
15. Stand at the back of the climber and face the disk assembly. The drive belt must be
positioned over the disk hub and behind the drive belt idler (refer back to Diagram 7.15).
Line up the drive belt in the center of the grooves on the disk hub.
Note:
Place the four flanges inside of the sheave brackets when you perform the next step.
16. Lift the drive belt from the disk hub. Push the sheave assembly through the belt. Place the
belt on the sheave shaft as you slide the sheave assembly into the sheave brackets (see
Diagram 7-.18).
Note:
Perform Steps 17 through 19 for each bearing you are mounting on the sheave shaft.
17. Hold the flange on one end of the sheave shaft against the sheave bracket. Place two bolts
through the sheave bracket and flange.
18. Slide the bearing next to the sheave bracket. Hold the bearing in place.
19. Slide the second flange next to the bearing and onto the bolts positioned through the first
flange and sheave bracket. Using your fingers, thread the two locknuts onto the bolts.
