Standard Mounting

1. Make sure the cone on the bushing and the inside of the driven product is clean and free of oil or any anti-seize lubricant.
2. Slide QD bushing on the shaft, flange end first, then assemble key.
3. Place the QD bushing on the shaft. Use only a standard Allen key to tighten the set screw on the key (hand-tight). Don’t push too hard.
4. Slide the large end of the sprocket or other part taper hole into place over the cone, aligning the drilled bolt holes on the sprocket or other part with the taper holes in the bushing flange. Then assemble the pull-up bolt and lock washer.
5. Tighten the pull-up bolts alternately and evenly to the tightening levels shown in the torque table below. Do not use extensions on 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 ensure a satisfactory tapered grip and press fit. NOTE: This gap must not be closed.
