TAPER BUSHING & SHEAVE INSTALLATION

Do not use lubricants during installation as this may cause sheave breakage.

Make sure the bushing and bore of the sheave are free of dirt, paint, metal chips, etc. Insert cap screws and lockwashers engaging only 2 or 3 threads.

With key in the keyway, slide the loosely assembled unit onto the shaft and position for good belt alignment. Temporary shimming under the pulley may make it easier to position.

Carefully tighten cap screws alternately and progressively until tapers are seated (about 5 FT-LB). Check sheave alignment and runout (wobble).

Continue careful alternate and progressive tightening of cap screws to 10 FT-LB. Maximum torque should be achieved on each individual bolt only two times.
