MAINTENANCE
Once both pulley and hub start seperating, attempt to move assembly on shaft.
Never hammer edge of pulley which may crack. To move assembly, a soft blow hammer
may be used on bushing only.
If the pulley is free and the bushing is still tight on shaft, it may be necessary to wedge a screwdriver in saw slot
of bushing to loosen and move hub.
Do not apply excessive force which may split bushing.
Never apply lubrication to threads or mating surfaces when assembling pulley and bushing.
After correctly locating hub and placing key in shaft keyway, move pulley into position over
taper hub and align tapped holes with through holes in hub. Install all mounting cap screws . Carefully tighten
the cap screws alternately and progressively until tapers are seated. Check alignment of pulley and proceed to
carefully tighten to 40 ft lbs torque. Maximum torque should be reached on each individual bolt only twice in the
consecutive tightening.
