The number two (secondary) circuit consists of the area between the secondary piston and the exhaust cavity. [. . . ] Use only genuine Bendix ® replacement parts, components and kits. Replacement hardware, tubing, hose, fittings, etc. must be of equivalent size, type and strength as original equipment and be designed specifically for such applications and systems. Components with stripped threads or damaged parts should be replaced rather than repaired. Do not attempt repairs requiring machining or welding unless specifically stated and approved by the vehicle and component manufacturer. Prior to returning the vehicle to service, make certain all components and systems are restored to their proper operating condition. VALVE REMOVAL 1. Identify and mark or label all air lines and their respective connections on the brake valve to facilitate ease of installation. Remove the valve from its mounting on the vehicle. For manifold-type valves, remove the brake valve and manifold, in tact, from the vehicle. WARNING!PLEASE READ AND FOLLOW THESE INSTRUCTIONS TO AVOID PERSONAL INJURY OR DEATH: When working on or around a vehicle, the following general precautions should be observed at all times. Park the vehicle on a level surface, apply the parking brakes, and always block the wheels. Stop the engine and remove ignition key when working under or around the vehicle. When working in the engine compartment, the engine should be shut off and the ignition key should be DISASSEMBLY (SEE FIGURE 9) The following disassembly and assembly procedure is presented for reference purposes only. Always have the appropriate maintenance kit on hand, and use its instructions in lieu of those presented here. Refer to Figure nine throughout the procedure. 5 CAUTION: The brake valve may be light clamped in a bench vise, but overclamping may damage the valve and cause leakage and/or malfunction. If a vise is used, clamp on the supply and delivery ports on opposing sides of the valve's primary body. On valves that have a manifold on the engine compartment side, remove the bolts that secure the manifold to the valve. Separate the valve and manifold and remove the sealing rings and adapter sleeves. Remove the four cap screws(16) that secure the primary body to the secondary body. Separate the two body halves and remove and discard o-ring(17). Pull secondary piston(18) out of the primary body and remove and discard o-rings(19 & 20). Remove and discard snap ring(10) from the secondary body while manually holding and compressing valve seat(11) in place. [. . . ] Install piston retaining ring(1) in its groove in the secondary body, making certain it is fully seated in the groove. Install plunger(21) in its return spring(22). Install the spring and plunger on secondary piston(18). While manually depressing and holding the plunger and spring on the piston, slide plunger and spring retainer(23) into place so that it secures both the plunger and spring to the piston. [. . . ]
