Inspection of Reel Motor
GENERAL
1. Clean and dry all parts.
2. Remove nicks and burrs from all parts with emery
cloth.
GEAR ASSEMBLY
1. Inspect drive gear assembly (3) for broken or cracked
keyway.
2. Inspect both the drive gear (3) and idler gear (2)
shafts at bearing point for rough surfaces and excessive
wear.
3. If shaft measures less than .686 in bearing area, the
gear assembly should be replaced. (One gear assembly
may be replaced separately. Shafts and gears are avail-
able as assemblies only.)
4. If gear width is below 1.327, gear assembly should be
replaced.
5. Inspect gear face for scoring and excessive wear.
6. Retaining ring (12) on shaft assemblies should be in
groove.
7. If edge of gear teeth are sharp, break edge with
emery cloth.
FRONT PLATE, BODY, BACK PLATE, AND RELIEF
VALVE
1. Inspect I.D. of bushings in front plate (8), body (6),
and back plate (21). If I.D. exceeds .693, front plate,
body, or back plate should be replaced. (Bushings are
not available as separate items.)
2. Back plate assembly (21) should be replaced if I.D. of
gear pocket exceeds 1.719.
3. Check for scoring on face of front plate (8), body (6),
and back plate (21). If wear exceeds .0015, front plate,
body, or back plate should be replaced.
4. If the relief valve kit (15) was removed, inspect valve
bore in the back plate (21) for dirt, debris, and damage.
Clean bore of dirt and debris. Replace back plate if bore
or valve seating surfaces are damaged.
IMPORTANT: The plug (17), shim (18), spring (19),
and ball (20) must be replaced as a complete unit.
5. If the relief valve kit was removed, inspect plug (17),
shim (18), spring (19), and ball (20) for wear and dam-
age. Replace parts as necessary.
Reassembly of Reel Motor
1. If the relief valve kit was removed, install ball (20),
spring (19), shim (18), new O–ring (16), and plug (17)
into the back plate (21). Torque plug from 10 to 12 ft–lb
(1.4 to 1.7 kg–m).
2. Retaining ring (12), shaft seal (13), back–up washer
(14), and O–rings (5) should be replaced as new parts.
3. Install O–rings (5) in grooves of front plate (8) and
body (6).
4. Install body (6) in front plate assembly (8) noting posi-
tion of scribe line.
5. Install dowel pins (7) in body (6) and front plate as-
sembly (8).
6. Dip gear assemblies (2 & 3) into oil and slip into body
and front plate bushing.
7. Install back plate assembly (21) noting position of
scribe line. Install cap screws (9), draw up bolts evenly
and torque to 22–25 ft. lbs.
8. Install new back–up washer (14) on drive shaft.
Oil shaft seal (13) liberally. Work shaft seal (13) over
drive shaft taking care not to cut rubber sealing lip.
9. Seat shaft seal (13) by tapping with plastic hammer.
Install new retaining ring (12).
10. Replace key (4) in drive shaft (3).
11. Install drive pulley (11) on drive shaft.
12. Tighten set screws (10) in drive pulley (11).
