NOTE: The reel bearings and grease seals are press fit
on the cutting reel shaft and should remain on the reel
when removing the LH side plate.
10.Remove shoulder bolts (item 7) and flange nuts that
secure the LH side plate to the cutting unit frame. Re-
move the LH side plate from the reel shaft, rollers, bed-
bar assembly and cutting unit frame.
CAUTION
Contact with the reel, bedknife or other cutting
unit parts can result in personal injury. Use
heavy gloves when removing the cutting reel.
11. Carefully pull the cutting reel with bearings, grease
seals and splined inserts from the RH side plate.
12.Inspect and service cutting reel assembly as re-
quired (see Reel Assembly Service in this section).
Reel Assembly Installation (Fig. 33)
1. Thoroughly clean side plates and other cutting unit
components. Inspect side plates for wear or damage
and replace if needed.
NOTE: Check that grease seals on cutting reel shaft
are flush to 0.060” (1.5 mm) away from retaining ring on
reel shaft. If necessary, adjust position of grease seals
to allow proper clearance.
2. Make sure that grease seals and bearings are prop-
erly greased and positioned on cutting reel (see Reel
Assembly Service in this section). Apply thin coat of
grease to outside of grease seals and bearings on cut-
ting reel to ease reel installation. Also, apply grease to
bearing bores and threads in side plates.
CAUTION
Contact with the reel, bedknife or other cutting
unit parts can result in personal injury. Use
heavy gloves when installing the cutting reel.
IMPORTANT: During cutting reel installation, keep
inner and outer bearing races aligned. If bearing
races are not aligned, binding will occur and reel
installation may cause bearing damage. Use reel
bearing installation tool (Toro part number
117--0975) to help with bearing alignment during
reel installation.

3. Using reel bearing installation tool (see Special Tools
in this chapter) to keep reel bearing aligned, carefully
slide the cutting reel with bearings and grease seals into
the RH side plate. Make sure that bearing is fully seated
into side plate.
4. Loosen set screw (item 20) and back--off (loosen)
bearing adjuster nut one complete turn.
5. Slide the LH side plate onto the cutting reel assem-
bly, front roller and rear roller. Make sure that reel end
in RH side plate does not shift in position.
6. Install shoulder bolts (item 7) and flange nuts that se-
cure the LH side plate to the cutting unit frame. Torque
the shoulder bolts from 27 to 33 ft-lbs (37 to 44 N--m) .
7. Apply Loctite #243 (or equivalent) to threads of
flange head screw that secures support tube, frame
spacer and carrier frame to LH side plate (Fig. 35).
Install screw and torque from 27 to 33 ft-lbs (37 to 44
N--m) . After tightening screw, check the clearance be-
tween the carrier frame and side plate. If clearance is
more than 0.090” (2.3 mm), remove flange head screw
and position shim(s) (part number 67--9410) between
carrier frame and side plate so that clearance is less
than 0.090” (2.3 mm). Make sure that the carrier frame
pivots freely after assembly.
8. Install cap screw and flat washer that secure rear
grass shield to LH side plate (Fig. 35). Torque screw
from 15 to 19 ft-lbs (20 to 25 N--m) .
9. Secure the bedbar assembly to LH side plate (see
Bedbar Installation in this section).
10.Secure front and rear rollers to LH side plate (see
Front Roller Installation and Rear Roller Installation in
this section).
