Standard Mounting
1. Be sure that the tapered cone surfaces on the bushing and the inside of the driven product is clean and free of oil or any anti-seize lubricants.
2. Slide the QD bushing on shaft, flange end first, then assemble key.
3. Position the QD bushing on the shaft. Tighten the set screw over the key (hand tight) with a standard Allen wrench only. Do not use excessive force.
4. Slide the large end of sprocket or other part taper bore into position over the cone aligning drilled bolt holes in the sprocket or other part with tapered holes into flange of bushing. Then assemble the pull-up bolts and lock washers.
5. Tighten pull-up bolts alternatively and evenly to tightness indicated in the torque table below. Do not use extensions on the wrench handles. There should now be a gap between the face of the sprocket or other part hub and the flange of the QD bushing to insure a satisfactory cone grip and press fit. Caution: this gap must not be closed.

1. Remove all pull-up bolts and screw them into tapped holes in sprocket or other part, against flange of QD bushing to break the cone grip.
2. Loosen set screw and slide QD bushing from shaft.

Warnings: use of anti-seize lubricant on tapered cone surfaces or on bolt threads when mounting may result in damage to sheaves and sprockets. This voids all manufacture's warranties.
