IMPORTANT: If rear roller brush drive is on left
side of cutting unit, drive shaft has l eft hand
threads and can be identified by a groove on the
flange. If th e rear roller brush drive is on right
side of cutting unit, drive shaft has right hand
threads and does not have a groove on the flange
(Fig. 70).
A. Apply Loctite #243 (or equivalent) to threads of
drive shaft. Thread drive shaft into cutting reel and
torque from 85 to 95 ft--lb (115 to 128 N--m).
B. Make sure that O--ring is placed on inner flange of
drive housing.
C. Position housing to cutting unit side plate and se-
cure to cutting unit with two (2) socket head screws.

lent) to threads of fasteners and torque fasteners as
shown in Figure 68.
B. Apply a light coating of grease to inner diameter
of the grommet in drive bearing housing before in-
stalling brush plate.
