AIR LINE FITTINGS To remove an air supply line from an air compres- sor assembly air line fitting. Push in (toward re- The fitting has a unique push-in feature. A brass type collet locks the air line in place. One rubber AIR CHECK, RESIDUAL The air dryer has a valving arrangement that maintains 172 to 276 kPa (25 to 40 psi). To test this function, perform the following proce- dure: (1) Remove the air line from the dryer and strut or spring. Attach a piece of bulk nylon tubing to one (2) Attach another piece of nylon tubing from the dryer (compressor) to other side of the pressure A compression ball sleeve nut and sleeve for 3/16 inch tubing with ball sleeve connector and an inter- (3) Activate compressor by grounding pin 508 to pin x 20 (See Control Module Connector), cycle unit COMPRESSOR PERFORMANCE TEST This test can be performed on the vehicle to evalu- ate compressor current draw, pressure output, and (1) Disconnect the compressor motor wiring har- ness connector. (2) Disconnect air line between dryer and strut or spring solenoid. (3) Connect an air pressure gauge into the system (Fig. 8). (4) Connect an ammeter in series between the red wire terminal on compressor connector and a 12 volt (5) If the current draw to the compressor motor ex- ceeds 30 amperes, replace the compressor assembly. AIR LEAK CHECK (1) Check all air line to connector joints. • Air line to compressor connectors. • Air line to solenoid. (2) Check the rubber membranes. • Front struts. • Rear springs.
