The brake cylinder assembly, the three planet carrier sub-
assemblies, the overrunning clutch assembly, and the
hydraulic motor subassembly should be assembled fol-
lowing the procedures in this manual before starting this
procedure.
Unless a specifi c torque value is given in the procedure,
all fasteners should be torqued to values in the torque ta-
ble in this manual.
1. Set the base angles (73 and 74) on a work table or
on the fl oor and install the support end bearing leg
(38) using capscrews (77), lockwashers (78), and nuts
(79). Ensure the bearing leg is in the proper orienta-
tion. Torque fasteners to torque table value. Install
grease fi tting (76) into bearing leg.
2. Bolt the two shifter fork bracket halves (58) to the bear-
ing leg (38). If the winch uses an air cylinder (5) for
freespool shifting, the brackets for mounting the air
cylinder are installed using the same bolts (34) on the
opposite side of the bearing leg.
3. Install the clutch shifter fork (102) onto the brackets
with the clevis pin (98). Install cotter pin (99) and bend
ends back to secure clutch shifter fork in place.
4. Place the sliding clutch (101) on a work bench. Se-
cure the two clutch rider halves (48 and 49) into the
sliding clutch groove using capscrews (56), lockwash-
ers (68), and nuts (63). Install grease fi tting (76) into
clutch rider.
5. Use an overhead hoist and stand the base angles ver-
tically with the clutch end on the ground. Place a wood
spacer block under the bearing leg to keep the base
angles level.
6. Apply a light coat of grease to the bearing leg (38)
bushing and the splines on the sliding clutch (101).
Set the sliding clutch (101) into the clutch fork slots
(102) on the bearing leg in preparation for installing the
drum shaft.
7. Install the retaining ring (75) into the groove in the drum
shaft (1). Apply a light coat of grease to the splines of
the drum shaft and the machined surface of the drum
shaft that will slide through the bearing leg (38) bush-
ing.
8. Put a 5/8” -11 eye-bolt into the gearbox end of the
drum shaft. Use an overhead hoist to lower the drum
shaft (1) through the sliding clutch (101) and into the
bearing leg bushing (38).
9. Slide the spacer (81) down the drum shaft. It will rest
on the retaining ring (75).
10. Install the two dowel pins (83) into the winch drum. In-
stall clutch plate (103) onto dowel pins and install cap-
screws (80) and lockwashers (23). Torque capscrews
to value in torque chart.
11. Apply a light coat of grease to the bushings on each
end of the winch drum. Secure the winch drum on the
gearbox end with lifting straps or a lifting fi xture and
use an overhead hoist lower it onto the drum shaft.
12. Place thrust washer (82) on top of the bushing in the
winch drum. The chamfered face of the thrust washer
must face toward the winch drum.
13. Install seal (33) into seal container (60). Apply a non-
hardening sealant such as Loctite Aviation Gasket
Sealant to the outside diameter of the seal before in-
stallation in seal container. Install o-ring (61) into seal
container.
14. Place the motor end support (34) on a clean work
bench. Install seal container (with seal and o-ring
installed) into motor end bearing leg (34). Install the
bearing (35) in the opposite side of the motor end sup-
port.
HP125B UPPER LEVEL ASSEMBLY
The complete winch assembly weighs approximately
1800 lbs (817 kg). Ensure the hoist and rigging are
rated for this weight. Using a hoist or rigging with insuf-
fi cient rating may result in personal injury or death.
The winch base angles and bearing leg weighs about
320 lbs (145 kg). Ensure the hoist and rigging are rated
for this weight. Using a hoist or rigging with insuffi cient
rating may result in personal injury or death.
The winch drum weighs about 400 lbs (182 kg). Ensure
the hoist and rigging are rated for this weight. Using a
hoist or rigging with insuffi cient rating may result in per-
sonal injury or death.
The winch drum shaft weighs about 142 lbs (65 kg).
Ensure the hoist and rigging are rated for this weight.
Using a hoist or rigging with insuffi cient rating may re-
sult in personal injury or death.
