•
Re-tighten the bleeder screws and allow the actuator to return.
•
Repeat the cycle until actuator is firm.
•
Make several static brake applications and then repeat the cycle once more.
The closed circuit hydraulic system must not leak. Even the smallest leak could defeat what would oth-
erwise be a well operating and effective brake system. It could eventually deplete the reservoir and re-
duce the braking pressure. To avoid leaks...
•
Check connections during the bleeding and static brake processes to be sure they are tight.
•
Always re-install new hoses, lines and fittings if they look the least bit questionable.
It is impossible to over emphasize the importance of cleanliness at installation. Always...
•
Use good, clean, quality fluid which conforms to S.A.E. Spec. No. J 703 or D.O.T. 3 or 4. Do not use
hydraulic oil.
•
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 brake fluid level and clean brake fluid added as required.
3.042 INSTALLATION OF 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 /
2
- 20 UNS.
The caliper brake assembly is mounted at the factory on a bracket attached to the hanger. 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. Install the hydraulic line running from the hydraulic actuator in to the inlet port (
1 /
8
- 27 NPT) of
the caliper brake assembly. The brake line should be rated for 1500 psi (10342 kPa) minimum.
Make the necessary hydraulic connections to the reservoir and actuator.
3. The closed circuit hydraulic system is shipped void of any fluid. Fill the system with brake
fluid, do not use hydraulic oil.
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 brake fluid level and add brake fluid if necessary.
