Installation
1. Be sure the tapered cone surfaces of the busing and the inside of the sprocket hub are clean.
2. Place bushing in sprocket, sheave, pulley or other QD parts.?
3. Place cap screws and lock washers loosely in pulling holes. ?Bushing remains fully expanded to assure sliding fit on shaft.
4. With key on shaft, slide sprocket to desired position on shaft. Be sure heads of cap screws are on outside.
5. Align sprocket. Tighten screws alternately and progressively-until they are pulled up tight. To increase leverage, use wrench or length of pipe. Do not allow sprocket to be drawn in contact with flange of bushing; there should be a gap from 1/8” to 1/4”

Caution:
When mounting screws, apply pressure by hand only. If extreme tightening forces are applied, bursting pressures will be created in the sprocket hub. There should be a gap of 1/8” to 1/4” between the face of the sprocket hub and the flange of the QD bushing. The gap must not be closed. If the gap is closed under normal tightening, the shaft is seriously undersized.

Removal
