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 at-
tached 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 ob-
tained 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 minimum.
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 operation.
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 1/8 - 27 NPTF
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 ser-
vice personnel must verify which fluid to use for a specific winch, as the two different fluids are not inter-
changeable
.
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 necessary.
