Standard Mounting1. Be sure that the tapered c1 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 Q_D bushing on shaft, flange end first, then assemble key.3. Position the Q_D bushing on the shaft. Tigh10 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 c1 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. Tigh10 pull-up bolts alternatively and evenly to tightness indicated in the torque table below. Do not use ex10sions 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 Q_D bushing to insure a satisfactory c1 grip and press fit. Caution: this gap must not be closed. Dismounting1. Remove all pull-up bolts and screw them into tapped holes in sprocket or other part, against flange of Q_D bushing to break the c1 grip.2. Loosen set screw and slide Q_D bushing from shaft.Warnings: use of anti-seize lubricant on tapered c1 surfaces or on bolt threads when mounting may result in damage to sheaves and sprockets. This voids all manufacture’s warranties. Tel: +86-57188220973 Mail us:[email protected]
