8 Cyclo® BBB4 Quick Start Guide
11
Tighten bushing bolts to the correct torque value.
• Following a star pattern, use a torque wrench to
gradually tighten each socket head cap screw in 20%
increments.
• Refer to Table 2, Taper-Grip® Bushing Bolt Tightening
Torques, for the correct operational screw torques.
12
In order to prevent corrosion, apply grease to the exposed portion of the
driven shaft.
• After installing and tightening the bushing bolts with
a torque wrench, apply grease or an anti-corrosion
product to the exposed portion of the shaft.
13
After the reducer has been running for 20 to 30 hours, re-torque the
screws to the values in Table 2. Screw torques should be subsequently
checked at normal service intervals (i.e. every 6 months).
14
For units that include a bushing safety cover, reinstall the guard over
the Taper-Grip® bushing.
Do not operate unit until the torque arm has been attached
to the unit and fixed to a rigid structure. The torque arm
prevents counter-rotation during unit operation. Refer
to torque arm Installation section in this manual for
instructions.
