Winch Mounting
It is important to mount the winch securely so the three major sections (the motor end, the cable drum, and the gear
housing end)are properly aligned. Excessive bushing wear and difficulty freespooling are usually symptoms of
misalignment.
If the winch is mid-mounted, attach at least one tie-plate to the mounting feet at the bottom of the winch to maintain
alignment. If the winch is foot mounted, attach at least one tie-plate at the midpoint to maintain alignment. It is always
preferred to use both tie-plates in the final installed configuration.
Contact your local RAMSEYWINCHdistributor or RAMSEYWINCHcustomer service for the recommended mounting
kit. The mounting kit will allow the winch to be mounted in upright or midmount applications and meets the criteria of
serving as a solid and true mounting surface.
If not using the RAMSEYWINCHmounting kit, or a RAMSEYWINCHmounting kit is not available, use the mounting
hole patterns described in the Dimensional drawings. The mounting surface must be flat within 0.015 in. and sufficiently
stiff to resist flexing.
If angles or a steel plate are used in mounting the winch, attach the provided tie-
plates to the remaining mounting pads to the either the side or foot.
