It is most important that this winch be mounted securely so that the three major sections (the clutch hous-
ing end, the cable drum and the gear housing end) are properly aligned. All standard model DC-300 Series
Winches are furnished with recommended mounting angles. Angle size is
1/4 x 2-1/2 x 2-1/2 x 36" Lg. high strength (50,000 PSI yield) steel angle.

ELECTRICAL CONNECTIONS

See dimensional drawing on page 17. Using a power cable with appropriate end terminals, connect the
positive (+) battery terminal to the 5/16" dia. stud on the plastic solenoid cover on the winch. IMPORTANT:
hold inner nut on stud with a wrench while tightening outer nut. Using a ground cable with appropriate end
terminals, connect the negative (-) battery terminal to motor isolated ground terminal. For distances up to
15 feet from battery to winch, use #2 Ga.

In applications where the chassis is non-grounded, a jumper

wire (#440315) will be required between the winch and the motor ground. This ground is required to
insure a suffi cient ground to operate the solenoid assembly (see diagram below).

For distances up to

15 feet from battery to winch, use #2 Ga. wire for the above connections. For distances greater than 15 feet,
use wire larger than #2 Ga.

CABLE INSTALLATION

1. Unwind cable by rolling it out along the ground to prevent kinking. Securely wrap end of cable, opposite
hook, with plastic or similar tape to prevent fraying.
2. Insert the end of cable, opposite hook end, into the 7/16" dia. hole in drum barrel. Secure cable to drum
barrel, using setscrew furnished with winch. TIGHTEN SETSCREW SECURELY.
3. Carefully run winch in the "reel-in" direction. Keeping tension on end of cable, spool all the cable onto the
cable drum, taking care to form neatly wrapped layers.

WINCH MOUNTING

ADJUSTING THE OIL COOLED WORM BRAKE

The oil-cooled, fully adjustable, automatic safety brake operates in the worm housing lubricant, all parts being
submerged in oil. When the brake wears to the point that the load begins to rift, the brake can be adjusted as
follows:
1. Loosen the lock nut on the adjusting screw.2. Tighten the brake by turning the adjusting screw clockwise.
CAUTION: Only 1/4 turn is usually required to adjust the brake.
Over-tightening can cause overheating, and damage to the brake
parts. Tighten the lock nut after adjustment is completed.

If the brake does not respond to adjustment then a new leaf spring and brake disc is needed. A torque wrench
can be equipped with a special adapter to fi t the input shaft (worm) of the winch. The adapter can be made by
welding a nut to the end of a piece of tubing as shown in the following fi gure.
