User manual BENDIX ROTO CHAMBERS

[. . . ] A lock nut and yoke with pin are screwed on the threaded push rod. The long stroke Type 50 employ a 1/2 in. The forward motion of the diaphragm guide and diaphragm forces the push plate and push rod forward. When the rotochamber is used to actuate cam type foundation brake assemblies, the yoke is connected to a slack adjuster which in turn is connected to the brake cam shaft. [. . . ] The yoke should be adjusted on the push rod so that with brakes released the angle formed by the push rod and slack adjuster will be greater than 90° and all slack adjusters should be at the same angle. With properly adjusted brakes applied, the angle should still be greater than 90°. DISASSEMBLY For ease in disassembly, if the rotochamber has been in service and shows signs of rust accumulation, it is recommended that the chamber be immersed and soaked in the cleaning or rust dissolving solvent for 24 hours. Remove cover, springs and spring guides (if so equipped). These nuts secure the outer clamp to the body and are located at the air inlet end of the rotochamber. Grasp the push rod and by pulling and wiggling the entire assembly consisting of push rod and plate, diaphragm guide, diaphragm, inner and outer clamps should ease out of the body. Remove nuts from inside of diaphragm guide. Disassemble inner diaphragm clamp, diaphragm and push plate rod assembly from the diaphragm guide. OPERATING AND LEAKAGE TESTS A. Apply brakes and observe that the push rods move out promptly and without binding. Release brakes and observe that the push rods return to the released position promptly and without binding. Push rod travel should be as short as possible without brakes dragging. Adjust travel of push rod at slack adjuster if necessary. Loosen rubber boot from around push rod hole in cover. Coat area with soap suds and check for leakage. If leakage is detected, the diaphragm must be replaced. CLEANING AND INSPECTION 1. Clean all metal parts in a good cleaning solvent. Carefully inspect all metal parts for cracks, distortion or damage. Replace any parts not considered serviceable. Replace diaphragm and rubber boot. REMOVING 1. Remove the rotochamber. 2 ASSEMBLY 1. Position the diaphragm on end in the inner diaphragm clamp. The smaller diameter end of the diaphragm should be against the diaphragm clamp. Place and install the diaphragm guide within the diaphragm and over the inner diaphragm clamp studs. [. . . ] Never exceed manufacturer's recommended pressures. Never connect or disconnect a hose or line containing pressure; it may whip. Never remove a component or plug unless you are certain all system pressure has been depleted. Use only genuine Bendix ® replacement parts, components and kits. [. . . ]
