Note: Do not lubricate the bushing taper, hub taper, bushing bore, or the shaft. Doing so may
result in sprocket/sheave hub fracture. DO NOT USE LUBRICANTS
4. With the key resting in the shaft keyway, position the sprocket/sheave and bushing assembly
onto the shaft allowing for small axial movement of the sprocket/sheave which will occur during
the tightening process.
Note: When mounting sprockets/sheaves on a vertical shaft, precautions must be taken to
positively prevent the sprocket/sheave and/or bushing from falling during installation.
5. Alternately torque the bushing bolts until the sprocket/sheave and bushing tapers are
completely seated together (use approx. half of the recommended bolt torque; see Table 1).
Note: Do not use worn hex key wrenches. Doing so may result in a loose assembly or may
damage bolts.
6. Check the alignment and axial sprocket/sheave run out (wobble), and correct as necessary.
7. Continue alternate tightening of the bolts to the recommended torque values specified in
Table 1 below.

Caution: Excessive bolt torque can cause sprocket/sheave and/or bushing breakage.
Note: To insure proper drive performance, full bushing contact on the shaft is
recommended.
Table 1 – Taper–Lock Bushing Bolt Torque Values
8. To increase the bushing gripping force, firmly tap the face of the bushing using a brass drift
or punch (Do not hit the bushing directly with the hammer).
9. Re-torque the bushing bolts after Step 8. After reaching the recommended bolt torque value
once, stop. Continued tightening to the recommended torque level will over insert the bushing.
10. Recheck all bolt torque values after the initial drive run-in, and periodically thereafter.
Repeat steps 5 through 9 if loose.
