Winch Installation - BRADEN PD12C Series Installation Maintenance And Service Manual

1. The winch should be mounted with the centerline
of the drum in a horizontal position. The mounting
plane of the base may be rotated in any position
around this centerline.
75°
2. Because of the design of the mounting base, the
direction of line pull should only be as shown in
the above illustration. Line pulls in any other
direction must be approved by BRADEN
Engineering.
3.
When mounting the winch, use all eight (8)
mounting holes and grade 5 or better bolts and
nuts. Tighten to recommended torque.

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 accelerated wear and heat.
Also, be sure the winch is mounted on a flat
surface. If necessary, use shim stock to insure the
mounting surface is flat within 0.020 in. (0.5 mm).
VENT PLUG
ABOVE CENTERLINE
4. The vent plug must always be located above the
horizontal centerline. If the winch is mounted on a
pivoting surface, be sure vent plug remains above
the centerline in all positions. If necessary,
reposition bearing support and vent plug as
follows:
A. Remove bearing support bolts.
B. Rotate bearing support until vent plug is
positioned correctly and bolt holes are
aligned.
C. Evenly tighten bolts to recommended
torque.
5. Hydraulic lines and components that operate the
winch should be of sufficient size to assure
minimum back pressure at the winch. The motor
manufacturer recommends that the back pressure
not to exceed 100 psi (690 kPa) for optimum
motor seal life. 150 psi (1,030 kPa) is the
maximum allowable back pressure. The standard
winch is supplied with the motor internally drained.
If high back pressures are encountered, the motor
may be externally drained directly to tank to
improve motor seal life. For back pressures
exceeding 150 psi (1,030 kPa) consult BRADEN
Service Department.
6. The winch should be mounted perpendicular to an
imaginary line from the center of the drum to the
first sheave to insure even spooling. Make certain
the fleet angle does not exceed 1-1/2 degrees.
