Mile Marker 75-50050C, Installation And Operator'S Manual

GETTING STARTED

Unpacking Your Winch

Typical Installation

Unpack your new Mile Marker winch and ensure that all the parts are included by referring to parts list and exploded view drawings provided in this manual.

Depending on amount of clearance between winch mount tray and winch body, attach the roller fairlead with two bolts (B-3/8 16 X 1¼ SS Hex Head Bolt) through 
roller fairlead and pre-drilled holes on front of winch mount tray and attach with 3/8 SS nuts (not provided) . When facing grill of truck, position the winch with the hydraulic 
2-speed levers to the left (passenger side). The Free/Low lever will be on top. In this position, 4 mounting holes will be on the bottom on any style of Mile Marker winch.

Attach winch to winch-mount tray by screwing 4 bolts (C-3/8 X 16 X 1 SS Hex Head Bolt) and washers (D-3/8 SS Washer) through the pre-drilled holes in bottom 
of winch mount tray into bottom of winch body. Tighten to 35 ft/lbs. Make sure that you have AT LEAST 6 threads going into the winch legs, but NO MORE THAN 
10 threads going into winch leg.

NOTE:

 If you find any missing or broken parts, please call Mile Marker as soon as possible at the number present on the front page of this manual.

Winch Mounting

Your winch should be aligned and secured to a solid part of the vehicle (front or rear) where the full rated load will be evenly distributed.

NOTE: 

Mile Marker recommends the use of its mounting systems for proper winch installation and optimum winch performance. However, when 

not using Mile Marker Mounting System, ensure that the mounting platform is strong enough to meet the maximum rated load of the winch in use. 
Mile Marker recommends steel plates with thickness of at least 0.25”.

CAUTION: 

It is essential that the mounting surface be flat and the winch is mounted such that the three major sections (Gear housing end, 

drum and motor end) are in proper alignment.

CAUTION: 

When replacing the capscrews or when longer bolts are required, make sure that you use bolts of Grade 5 or greater.

Winch body on 9000 lb. and 10500 lb. winch has mounting holes only on the bottom. Winch body on 12000 lb. winch has four mounting holes 
on front, back, and bottom of the winch. This may allow the winch to be mounted easier on some winch mounts or for other applications.
The motor on Mile Marker 2-speed winches may also be rotated in 90º increments if needed. This may allow easier installation on somewinch mounts.
