With the pulley and shaft assembly on the floor, have another person slide the
pulley until it is approximately 8.7-9.02 cm (3.425-3.55 in.) from the end of the
shaft. Slowly tighten the bolts until the pulley starts to move to the end of the
shaft.

Tighten all three bolts by working around the bushing until none of the bolts will
turn at a torque wrench setting of 70 ft.-lb.
Note:
It is very important all three bolts on the bushing are tightened to a torque
wrench setting of 70 ft.-lb. Work around all three bolts a second time to verify.
The pulley should have moved to approximately 8.38 cm (3.30 in.) from the end
of the shaft.
10 Verify the pulley is 8.38 cm (3.30 in.) from the end of the shaft.
Note:
The measurement of 8.38 cm (3.30 in.) is not critical; however, this
measurement should be the same on both the movable and stationary dynos.
