3. Clean the bearings in solvent and dry. Replace
worn or badly pitted bearings. Pack the bearing
cups and cone with grease and reassembly.
Grease all lube fittings after reassemble.
4. Turn the adjusting nut slowly in a clockwise direc-
tion until all end play is removed and slight resis-
tance can be felt when turning the reel. Tap the
end of the shaft with a soft hammer, if turning
resistance is still present, back off the adjusting
nut 1/8 turn and tap with the hammer. Repeat if
necessary. The adjustment is correct when the
reel can be revolved freely and end play does not
exceed 0.010 inch (.25 mm).
5. Install the mower on the machine as described in
Section 12D.
CHANGING BLADE SPACING
Blade spacing of 0.75 in (19 mm) is standard on factory
built mowers (Figure 13B-2). Cutting widths can be
reduced or increased between 0.5 and 1.5 in (12.7 and
38 mm) in 0.25 (6.35 mm) increments by adding or
removing individual blades. To do this, follow the
instructions on the removal of individual blades.

REPAIR OF FRONT ROLLER,
GRASS SHIELDS, AND SCRAPERS
If the front roller, grass shields and grass shield scrap-
ers require repair or replacement, disassemble and
reassemble as shown in Figure 13B-3. Replace worn
or badly pitted bearings. Clean in solvent, dry, and
pack (with grease gun) bearings and bearing seals
before installing. Fill the lube fittings on the front roller
after reassembling.
NOTE:
When installing the front roller in a vertical reel
mower, the roller brackets must be assembled
with the roller in the forward position as shown in
Figure 13B-3.
