HYDRAULIC SYSTEMS

Refer to performance charts, below, to properly match your hydraulic system to the
HDG-350 winch performance. The charts consist of:

1. Line pull (lbs.) first layer vs. working pressure (P.S.I.). STATIC refers to lifting a
suspended load from rest; DYNAMIC refers to maintaining the motion of a moving
load.

2. Line speed, first layer (F.P.M.) vs. gallons per minute (G.P.M.).

Performance based on a motor displacement of 3.6 cubic inches with 15 GPM
maximum flow rate.

RE-ASSEMBLING AND CHECKING THE BRAKE

1. Press brake hub into place over worm shaft and key.

2. Assemble balls into appropriate slots of cam. Use stiff grease to hold balls into place
and slide cam over end of worm. Be sure that balls are secure, between cam slots
and hub slots. Refer to Diagram 1 on page 12.

3. Install brake disc.

4. Install retainer plate, smooth side toward brake disc.

5. Install the gasket on the cover with a small amount of grease or sealer

6. The coil spring goes over the adjusting screw on the inside of the cover.

7. Install the notches of the leaf spring on the pins protruding through the cover. The
hollow side of the leaf spring goes toward the brake.

8. Install brake housing cover, making sure the protruding pins go through the leaf
spring and into the holes on the retainer plate. Tighten capscrews to 7-8 ft. lbs.

9. Bolt cover into place with the mounting screws. Install drain plug and add 1 pint of
SAE 140 EP oil.

10. Turn winch in the reel in direction at least one turn of the input shaft.

11. Turn the adjusting screw in until it is finger tight.

TEST FOR PROPER BRAKE ASSEMBLY

After the brake has been adjusted to the proper torque setting (See page 11), disengage
clutch. Start vehicle engine and run winch in the reel in direction. Allow winch to run in
this direction for one minute.

Place your hand on the brake housing. If housing is not hot to the touch then run winch
in the reverse direction (cable out) for one minute. Brake housing should begin to heat.

When these conditions exist, proper installation has been made. If heating becomes
noticeable when running the winch in forward rotation (reel in direction) the brake should
be disassembled. When disassembled, place the brake balls in the alternate set of slots
in the cam plate, then carefully follow the instructions for reassembling and checking the
brake.
