4. Turn the wing nut counterclockwise to relax the
spring. As the cam clears the key in the fixed driven
shaft, there will be a slight clockwise rotation of the
cam. This is normal due to spring preload.
! WARNING
If at anytime the cam hangs up or the tool feels slack
and the spring is not completely extended, stop and
determine the cause. Failure to do so could result in the
driven pulley assembly suddenly coming apart and
severe injury or death could occur.
5. Completely relax the spring until all pressure is
removed from the compression yoke; then remove
the wing nut, compression yoke, snap ring, and cen-
tering bushing.
6. Remove the cam and spring; then remove the mov-
able driven sheave. Account for a square key.
7. Remove the fixed driven sheave from the compres-
sion tool base.
INSPECTING
1. Inspect the sheave faces for cracks, grooving, or
