Replacing V-Belt; Aligning Pulleys - Grizzly G0458ZX Owner's Manual

Replacing V-Belt

A worn/damaged V-belt will not provide optimum
power transmission from the motor to the drum
belt. Inspect the V-belt closely; if you notice
fraying, cracking, glazing, or any other damage,
replace the belt.
V-belt removal and replacement is simply a matter
of loosening the V-belt, rolling it off of the pulleys,
replacing it with a new belt, then re-tensioning.

Pulley alignment is an important factor in power
transmission and belt life. The pulleys should
be parallel to each other and in the same plane
(coplaner) for optimum performance.
Each pulley can be adjusted by loosening the set
screw that secures the pulley to the shaft, sliding
the pulley in/out, and retightening the set screw to
lock the pulley in place.
