WINCH AND WIRE ROPE
INSTALLATION
1. The winch should be mounted with the centerline of
the cable drum in a horizontal position. The mounting
plane of the winch may be rotated in any position around
this centerline providing the vent in the motor adapter
is above the centerline of the cable drum. The vent
should be as close to top dead center as possible.
2. When mounting the winch, use all four mounting holes
and Grade 8 bolts and nuts. Evenly tighten the nuts to
the torque in the Recommended Fastener Torque chart.
Make certain the winch drum is centered behind the first
sheave and the fleet angle does not exceed 1-1/2 de
-
grees. The winch should also be mounted perpendicu-
lar to an imaginary line from the center of the drum to
the first sheave to ensure even spooling.
Refer to the dimensional drawing section of this manual
for bolt hole size and pattern.
It is important that the winch is mounted on a surface that
will not flex when the winch is in use, and cause binding of
the gear train. Binding in the gear train will result in accel-
erated wear and heat. Also, the mounting surface should
be flat with +/- 0.020 inch. If necessary, install shims un
-
der the winch mounting pads to achieve even mounting.
3. The hydraulic lines and components that operate the
winch should be of sufficient size to assure minimum
back pressure at the winch. The back pressure at the
motor must not exceed 100 PSI (690 kPa) to maintain
full brake system design factor and optimum motor seal
life.
The winch directional control valve must be a three-posi-
tion four-way valve with a motor spool such that when the
valve is in the center position both work ports are open to
tank (open center, open port).
4. High-quality hydraulic oil is essential for satisfactory
performance and long hydraulic system component life.
Oil having 150 to 330 SUS viscosity at 100°F (38°C) and
viscosity index of 100 or greater will give good results un-
der normal temperature conditions. The use of an oil hav-
ing a high viscosity index will minimize cold start trouble
and reduce the length of warm-up periods. A high vis-
cosity index will minimize changes in viscosity with cor-
responding changes in temperature.
Maximum cold weather start-up viscosity should not ex-
ceed 5,000 SUS with a pour point at least 20°F (11°C)
lower than the minimum ambient temperature.
Under continuous operating conditions the temperature of
the oil at any point in the system must not exceed 180°F
(82°C). 120°F (49°C) to 140°F (60°C) is generally consid-
ered optimum.
In general terms:
For continuous operation at ambient temperatures be-
tween 50°F (10°C) and 110°F (43°C) use SAE 20W; for
continuous operation between 10°F (-12°C) and 90°F
(32°C) use SAE 10W; for applications colder than 10°F
(-12°C), contact the BRADEN/GEARMATIC Service De-
partment. The use of multiviscosity oils is generally not
recommended.
For winch gear oil, refer to lubricant specifications in the
Preventive Maintenance and Specifications section.
5. The hydraulic oil filter should have a 10-micron nominal
rating and be full-flow type.
6. The vent plug in the motor adapter must be located as
close to top dead center as possible. If the winch is
mounted on a pivoting surface, the vent plug must re-
main above the centerline of the cable drum to prevent
gear oil leakage.
7. Refer to the dimensional drawing for relationship be-
tween drum rotation and which port is pressurized.
WIRE ROPE INSTALLATION
03 and 04 DRUM
Take the free end of the wire rope and insert it through the
small opening of the anchor pocket you are going to use.
Loop the wire rope and push the free end about three-
fourths of the way back through the pocket. Install the
cable anchor with the small end toward the drum, then pull
the slack out of the wire rope. The cable anchor will slip
into the pocket and secure the wire rope to the drum. A
minimum of five wraps of wire rope should remain on the
cable drum at all times. Refer to General Safety Recom-
mendations section of this manual for additional informa-
tion.
