C. Install grease seals so that seal lips are positioned toward the brush.
Press seals into housing so that seal contacts bore shoulder.
3. Assemble roller brush components noting the following items:
A. Apply coating of grease to lips of grease seals in brush bearing housing
before inserting brush shaft into housing.
B. Position excluder seals on brush shaft so that seals just touch bearing
housings.
C. If driven pulley (item 12) was removed from roller brush shaft, apply
antiseize 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

IMPORTANT
The roller brush shaft must nor contact the cutting unit side plate.
Also, heavy brush contact on the rear roller will cause premature
brush wear.
4. Check that brush is parallel to rear roller with 1.5 mm (0.060”) clearance to
light contact with rear roller. If contact is incorrect, brush operation will be
adversely affected.
5. Lubricate grease fittings on brush housings until grease purges past inboard
seals. Wipe excess grease from seals and fittings.
