General Machine Products 70524 Adams CD3 Continuous Duty Winch - Manual (Page 10)

AK 7/18/2012 ver 5
The importance of cleanliness during installation cannot be over-emphasized.
♦ Caliper Drag Brakes on Adams Winches may be specified by the customer for brake fluid only or hydrau-
lic oil only. Installation and service personnel must verify which fluid to use for a specific winch, as the
two different fluids are not interchangeable. Always use good, clean, quality fluid that conforms to what is
specified on the brake components.
♦ Be sure all fittings and seats are clean before making connections.
♦ Clean the top of the reservoir before removing filler cap.
CAUTION: As a part of routine maintenance, it is recommended that brake hoses and brake lines
be inspected regularly. All damaged or worn parts should be replaced. The reservoir should be
checked for sufficient fluid level and clean fluid added as required.
3.042 CALIPER
BRAKE ASSEMBLY - The caliper brake assembly is mounted at the factory on two studs
attached to the hanger (steps 1- 4 have already been performed if the brake assembly was mounted at the factory).
1. Screw in brake module assembly (item 7) until a total clearance of approximately .012 in. (0,3 mm) is
obtained between the disc and lining.
2. Back off brake module assembly as required to position ports in vertical alignment.
3. Tighten lock screw with 1/8 in. Allen wrench.
4. Move bleeder screw to higher of 2 ports for ease of bleeding (both ports
1 /
8
- 27 NPTF).
5. Install hydraulic line from hydraulic actuator in lower port. The line should be rated for 1500-psi mini-
mum.
6. Bleed the system making sure all air is eliminated. Apply hydraulic pressure and check for leaks.
3.043 RESERVOIR AND ACTUATOR - The remote actuator is normally mounted at the rear of the body,
under the tail shelf. Find a location that is safe and convenient to the operator and within sight of the winch opera-
tion. Alternate mounting would be in accordance with end user specifications.
The reservoir should be mounted above, and as close as possible to the inlet fitting of the actuator. Both the inlet
and outlet fittings of the actuator are ½ - 20 UNS.
The reservoir should be mounted higher than the caliper brake assembly to facilitate bleeding. The flexible hose
should be connected to the outlet fitting of the actuator.
1. Mount actuator assembly, using four 5 /
16
in. diameter bolts, lock washers and locking nuts, as required.
Note: bracket may be used as template for drilling mounting holes.
2. Make necessary hydraulic connections to reservoir and caliper brake.
3. The closed circuit hydraulic system is shipped void of any oil. Fill the system with the correct fluid as
specified on the brake components: Brake Fluid or Hydraulic Oil. Note: Caliper Drag Brakes on Adams
Winches may be specified by the customer for brake fluid only or hydraulic oil only. Installation and
service personnel must verify which fluid to use for a specific winch, as the two different fluids are not
interchangeable.
4. Bleed the system making sure all air is removed from the system. Apply hydraulic pressure and check for
leaks. Make several applications to be sure actuator is working properly.
5. After bleeding is complete, check reservoir for sufficient fluid level and add correct type fluid if neces-
sary.
3.05 FULL
LOAD BRAKE - Although the full load brake is factory installed, procedures must be followed
during installation of the winch to ensure proper brake operation.
Bleeding the full load brake is required anytime air has been introduced into the system, and must always be per-
formed by the dealer during the winch installation, in order to assure proper release of the brake for winch drum
rotation. Bleeding is accomplished by pressurizing the system and loosening the bleeder screw on the top of the
brake. To avoid fluid loss or spillage, a hose should be connected to the top of the bleeder screw and the outlet of
the hose directed to a can or similar container. The brake should be bled until all the air is removed from the
brake. Several cycles of pressure bleeding may be required to remove all of the air from the brake.
