Atwood Hydraulic Brake System (part2)

"A" FRAME WELD-BETWEEN

1. Position actuator between A-Frame members with the leading edge of the A-Frame located a maximum of 5" from the back of the actuator (Figure 3, below).

2. Weld actuator to trailer tongue by welding along the entire length where trailer frame contacts actuator. Weld must be a minimum of 7" along each side. Make a 5/32" fillet weld (see Figure 3) No. E6011 A.W.S. welding rod (AC or DCRP). Use a 5/32" diameter rod, machine amps at 1 40 150 with 50 volts.

CAUTION: Breakaway cable and hook must not touch ground during welding operation.

WARNING: The brake actuator is not designed to withstand the torsional twist of the trailer "A" frame in service. Additional means, must be used to tie the trailer "A" frame members together (i.e. cross members, etc.).The cross member(s) should be comparable in strength to the trailer frame, and should be located as close to the brake actuator as possible.

NOTE: If Atwood top and bottom jack mounting plates are used, move the jack mounting plates as close to the brake actuator as possible and weld along the entire area where the plates and trailer frame contact. Use welding instructions given in Step No. 2 above.

PAINTING THE BRAKE ACTUATOR

Dip Painting Procedure

NOTE: Carefully perform instructions in the order given.

1. Plug vent hole in master cylinder boot.
2. Fully apply brake actuator.
3. Plug master cylinder outlet port (1/8" NPTF Thread).
4. Plug master cylinder reservoir port to prevent any paint from entering master cylinder.
5. Paint brake actuator.
6. Remove all plugs and fully release brake actuator.
7. Inspect for paint contamination of the master cylinder and the shock absorber shaft after painting. Replace parts if contamination with paint.
8. Continue with "Mandatory Functional Check" (Read on...).
