Reel and Bearing Removal and Installation

Removal (Fig. 58)
1. Remove reel motor from the cutting unit and the cut-
ting unit from lift arm (see Cutting Unit Removal and
Installation).
2. Place cutting unit on a level working surface.
3. Remove shield rod (2) from frame by removing both
cap screws (5) and flat washers (4).
4. Remove front roller from the cutting unit (see Front
Roller Removal and Installation).
IMPORTANT: Place strips of wood below the reel to
prevent the reel from dropping out of the cutting
unit when the bearing housings are removed.
5. Remove both bearing housings (10) by removing
the tapered lock nuts (8) and tapered screws (14) secur-
ing the housings to the frame. Pull both housings away
from the frame and away from the reel ends.
6. Remove reel (1) with the bearings (12) and grease
seals (13) from the cutting unit.
7. Remove bearing spacer (29) and flat wire spring
(11) from their bearing housings (10). Clean inside of
each housing. Both housings should be free of dirt and
debris.
Note: If bearings (12) are removed from the reel (1),
replace grease seals (13).
8. If necessary, remove bearings (12) and grease
seals (13) from the reel (1) as follows (see Inspection be-
low):
A. Prevent damage to bearings by pulling on the in-
ner bearing race.
B. Use bearing puller to remove bearings and
seals.

1. Inspect splined coupler (32) as follows (Fig. 58):
A. Remove retaining ring (31) and drive coupler
from the reel shaft (1).
B. Clean drive coupler. Coupler should be free of
dirt and debris.
C. Drive coupler should be free of bending and dis-

2. Inspect reel (1) as follows:
A. Check reel shaft for bending and distortion by
placing the shaft ends in V−blocks. Replace reel if

lows (Fig. 58):
A. Seals must be free of cracks and tears. Replace
seals as necessary.
B. Bearing roller balls must be free of deformation
and scoring. Replace bearing if necessary.
