2. If roller brush was removed from roller shaft, slide brush onto shaft while
rotating brush. Secure brush to shaft with two (2) J-bolts and lock nuts. Make
sure that the J-bolts are installed with the threaded portion on the outside of
the brush (Figure 196). Torque lock nuts from 2.3 to 2.8 N·m (20 to 25 in-lb).
3. Assemble the roller brush components using
the following items:
A. Apply the coating of grease to lips of grease seals in brush bearing
housing before inserting brush shaft into housing.
B. If driven pulley (item 12) was removed from roller brush shaft, apply
anti-seize lubricant to splines of pulley bore and slide pulley onto shaft.
Install and tighten flange nut until pulley is seated onto shaft and then
torque flange nut from 37 to 44 N·m (27 to 33 ft-lb). Use a ½ wrench on
roller brush shaft flats to prevent shaft from rotating when tightening nut.
C. Position excluder seals on brush shaft so that seals just touch bearing
housings.
D. If driven pulley (item 12) was removed, check and adjust alignment of
drive and driven pulleys (refer to
