Toro Greensmaster Flex 21 Service Manual page 110

CAUTION
Contact with the reel, bedknife, or other cutting
unit parts can result in personal injury. Use
heavy gloves when handling the cutting reel.
5. Position reel with pitch arms and bushings in frame
to accept bearing housings. The reel shaft end with key-
way should be on the left side of the frame.
6. Attach both bearing housings to frame and reel shaft:
IMPORTANT: On cutting units equipped with can-
nister seals, make sure that inner (black) seal bore
is completely free of lubricant before installing
bearing housings. Lubricant in the inner (black) seal
bore will allow cutting reel to rotate inside the seal
and reduce effectiveness of seal. Outer (blue) seal
will be easier to install and will not be adversely af-
fected with grease applied to inner bore.
A. Slide assembled bearing housings onto reel shaft
until the bearing inner race contacts the reel shaft
shoulder.
B. Install two plow bolts and tapered nuts and tight-
en only enough to hold bearing housings in position.
NOTE: The reel bearing lock nut has left hand threads.
C. Align bearing to cutting reel by installing the reel
bearing lock nut (right end of cutting reel) or the
pulley spacer, pulley and flange nut (left end of reel)
and tightening until contact with the bearing inner
race is made.
D. Using light, steady hand pressure, press bearing
housing to side plate. As an alternate method, slowly
tighten reel bearing lock nut (right end of cutting reel)
or the pulley spacer, pulley and flange nut (left end of
reel) to evenly install bearing housing.
E. Tighten two plow bolts and tapered nuts to secure
bearing housing to side plate.
F. Remove reel bearing lock nut, pulley spacer,
pulley and flange nut from reel.
7. Apply anti–seize lubricant to internal threads of reel
bearing lock nut. Block reel with a piece of wood to pre-
vent it from turning. Install and tighten the reel bearing
lock nut to the reel shaft.
8. Install spacer in left side reel bearing housing. Posi-
tion reel drive plate assembly and fit two locknuts, cap
screw and lockwasher that secure reel drive plate as-
sembly to side of cutting unit (Fig. 41). Tighten fasteners
to secure assembly.
Cutting Unit (Rev. C)
9. Install pulley spacer and woodruff key to reel shaft.
Apply anti–seize lubricant to internal bore of drive pulley
and position pulley on reel shaft. Install and tighten
flange nut that secures pulley to the reel shaft. Torque
flange nut from 40 to 50 ft–lb (54 to 68 N–m).
NOTE: The Flex 21 will have slightly greater reel drag
than other Toro greens mowers due to the reel seal de-
sign.
10.Check for free movement of reel assembly by rotat-
ing reel with pulley nut. Using an appropriate torque
wrench, make sure that reel rotates with less than 15 in–
lbs (1.7 N–m) force applied to pulley nut. If binding is
noted, identify and correct problem.
11. Install reel weight on right side of cutting unit with two
lock nuts.
12.Install reel drive belt to the pulley and drive assembly
(see Reel Drive Belt Replacement in Chapter 4 – Trac-
tion and Reel Drive Systems). Adjust drive belt tension
and install belt cover.
13.Install front roller (see Roller Installation in this sec-
tion).
14.Install bedbar to the mower (see Bedbar Installation
in this section).
15.Install cutting unit to traction unit (see Separating
Cutting Unit from Traction Unit in this chapter).
16.Complete mower set–up and adjustment sequence
(see Adjustments section of this chapter).
