5. Carefully slide the RH end of the cutting reel as-
sembly (no groove in reel shaft or on face of threaded
insert) into the RH side plate. Make sure that bearing is
fully seated into side plate.
6. Slide the LH side plate onto the cutting reel as-
sembly.
7. Install shoulder bolts and flange nuts that secure the
LH side plate to the cutting unit frame. Torque the shoul-
der bolts from 27 to 33 ft-lbs (37 to 44 N--m).
8. Apply Loctite #242 (or equivalent) to threads of
flange head screw that secures frame spacer and carri-
er frame to LH side plate. Install screw and torque from
27 to 33 ft-lbs (37 to 44 N--m). After tightening screw,
check the clearance between the carrier frame and side
plate. If clearance is more than 0.065” (1.6 mm),re-
move flange head screw and position shim(s) between
carrier frame and side plate so that clearance is less
than 0.065” (1.6 mm). Make sure that the carrier frame
pivots freely after assembly.
9. Install cap screw and flat washer that secure rear
grass shield to LH side plate. Torque screw from 15 to
19 ft-lbs (20 to 25 N--m).
10.Install the bedbar assembly (see Bedbar Installation
in this section).
11.Install front and rear rollers (see Front Roller Installa-
tion and Rear Roller Installation in this section).
12.Adjust cutting unit (see Cutting Unit Operator’s
Manual).
NOTE: The parallel position of the rear roller to the cut-
ting reel is controlled by the precision machined frame
and side plates of the cutting unit. If necessary, the cut-
ting unit side plates can be loosened and a slight adjust-
ment can be made to parallel the rear roller with t he
cutting reel ( see Leveling Rear Roller in this Chapter).
13.If cutting unit is equipped with optional groomer or
rear roller brush, install components for those options to
left hand side plate of cutting unit. See Chapter 8 -- Belt
Driven Groomer or Chapter 9 -- Universal Groomer for
information on groomer. See Rear Roller Brush in this
chapter for information on rear roller brush.
14.Tighten the spline inserts:
A. Insert a long--handled pry bar (3/8 x 12 inch with
a screwdriver handle recommended) through the
front of the cutting unit. The pry bar should pass
between the top of the reel shaft and the backs of
the reel blades so that the reel will not move.
