2.12 Crusher Sheave Removal
To remove the crusher sheave, refer to Figure 2-13
and proceed as follows:
1. Remove the take-up capscrews and thread
two of them into the tapped holes in the hub
of the sheave. Using the two capscrews as
back-off bolts, exert pressure by tightening
them against the flange of the bushing,
breaking the sheave grip on the bushing
cone. Remove the sheave.
2. Loosen sheave bushing clamp screws.
3. If necessary, insert a wedge such as a
screwdriver into the split in the bushing
flange and remove the bushing.
Figure 2-13 Sheave Assembly
NOTICE
Should there be difficulty “breaking” the fit
between the sheave and bushing, tap the
end of the shaft or bushing with a babbitt
hammer while maintaining back-off bolt
pressure, until the sheave is loose enough
to remove.
