INSTALLATION
4.
Tighten mounting bolts evenly and torque to 380 ft lbs (515
Nm) for dry thread fasteners. If the fasteners are plated,
lubricated or a thread locking compound is used, torque to
280 ft lbs (380 Nm).
5.
Maintain a fleet angle between the lead sheave and winch
of no more than 1-1/2°. The lead sheave must be on a
center line with the drum and, for every inch (25 mm) of
drum length, be at least 1.6 feet (0.5 metre) from the drum.
Refer to Dwg. MHP0498.
6.
Do not weld to any part of the winch.

Wire Rope
CAUTION
• Maintain at least 3 tight wraps of wire rope on the drum at
all times. Refer to Dwg. MHP0498.
Install the winch such that the wire rope, when at the take-off
angle limits, shown in Dwg. MHP1013, does not contact the
mounting surface.
DANGER
• Exceeding the wire rope take-off angles will cause the wire
rope to come into contact with the winch frame supports
resulting in damage to the wire rope and winch.
Prior to installing the winch, carefully inspect it for possible
shipping damage.
Winches are supplied fully lubricated from the factory. Check
oil levels and adjust as necessary before operating winch. Refer
to “LUBRICATION” section for recommended oils.
CAUTION
• Owners and users are advised to examine specific, local or
other regulations, including American National Standards
Institute and/or OSHA Regulations which may apply to a
particular type of use of this product before installing or
putting winch to use.
Mounting
Refer to Dwg. MHP0124 and Table 1.
Care must be taken when moving, positioning or mounting the
winch. Ensure that the winch, when lifted, will be properly
balanced. Determine the weight of the winch by referring to the
“SPECIFICATIONS” section. Lift the winch 3 to 4 inches (75
to 100 mm) off the ground. Verify winch is balanced and secure
before continuing lift.
Mount the winch so the axis of the drum is horizontal and the
motor control valve pad is not more than 15° off top vertical
center. If the winch is to be mounted in an inverted position, the
motor case must be rotated to position the control valve pad at
the top and adequate clearance must be provided for control
valve operation.
WARNING
Welded mountings
can fail.
Can cause severe
injury or death.
Do not weld, braze or
solder to winch.

WARNING
• Winch frame material is not suitable for welding. FA2A
winches must only be mounted by bolting to a suitable
foundation. Do not attempt to mount the winch by welding to
a foundation structure.
1.
The winch mounting surface must be flat and of sufficient
strength to handle the rated load plus the weight of the
winch and attached equipment. An inadequate foundation
may cause distortion or twisting of the winch uprights and
side rails resulting in winch damage.
2.
Make sure the mounting surface is flat to within 1/32 inch
(0.8 mm). Shim if necessary.
3.
Mounting bolts must be 3/4 inch-NC (18 mm) Grade 8 or
better. Use self-locking nuts or nuts with lockwashers.
