PART 2-6 - AIR SUPPLY SYSTEM 2-69 rate test gauge. The cut-in and cutout setting is made at the adjusting screw (Fig. 2). 1. With the engine running, build up air pressure in the system and observe the pressure registered by the dash gauge. 2. If the pressure build-up continues beyond 105 pounds before the governor cuts out, remove the cover from the top of the governor and loosen the lock nut. Turn the adjusting screw clockwise to lower the cut-out pressure. 3. With the engine running, slowly reduce the system air pressure by applying and releasing the brakes and observe the dash gauge pressure. 4. If the pressure drops below 80 pounds before the governor cuts in again, turn the adjusting screw counterclockwise to raise the pressure. Tighten the lock nut and install the cover after completing the adjustment. The air pressure range between cut-out pressure (maximum) and cut-in pressure (minimum) is fixed at about 20-25 pounds and cannot be adjusted. AIR RESERVOIR SAFETY VALVE The air reservoirs are connected into the air brake system. Drain cocks are provided at the bottom of each reservoir. A safety valve is installed on one of the reservoirs. When servicing the reservoirs, re^moval or installation of the air tube between the reservoirs can be made by loosening the reservoirs from the frame. To set the safety valve, loosen the lock nut, and turn the screw clockwise to increase the pressure setting, or counterclockwise to decrease the pressure setting. Connect regulated pressure to the reservoir and adjust the valve to relieve the pressure at 150 psi. Tighten the lock nut after making the proper adjustment. REMOVAL AND INSTALLATION VERTICALLY-MOUNTED COMPRESSOR—WITH GAS- ENGINE TRUCKS REMOVAL Depending upon the particular truck model and engine, compressors are mounted in various locations. Removal and installation procedures differ between vertically mounted units and side-mounted units. 1. Open the reservoir drain cocks to exhaust air pressure from the system. 2. Drain the cooling system. 3. At the compressor, disconnect the compressor air outlet line, the water inlet and outlet lines and the oil feed and oil return lines (Fig. 3). 4. Since the reservoir pressure hose is difficult to remove at the governor, disconnect the hose at the fitting on the opposite end. If the hose is to be replaced, disconnect it from the governor after the compressor has been removed. 5. Remove the four compressor to base plate bolts, slide the compressor inward on the base plate and disengage the drive belt; then remove the compressor. INSTALLATION 1. Transfer the pulley, Woodruff key and retaining nut to the new compressor. 2. Transfer the air outlet elbow and gasket, the water inlet and outlet fittings, and the oil inlet and outlet fittings to the new compressor. Apply sealer to all these parts. 3. Transfer the governor and gasket to the new compressor (two retaining bolts). Apply sealer. If the reservoir pressure hose is to be replaced, connect it to the governor at this time. 4. Transfer the air inlet filter and gasket to the new compressor (two retaining bolts). Apply sealer. 5. Position the compressor on the base plate and engage the drive belt to the pulley. 6. Install the four mounting bolts, slide the compressor away from the fan pulley until a Vi inch belt deflection is obtained, and tighten the bolts. 7. Connect the compressor air outlet line, the water inlet line and the water outlet line to the compressor. Connect the oil feed and the oil return lines to the compressor. 8. Connect the hose from the governor to the fitting on the reservoir pressure line. 9. Fill the cooling system, close the reservoir drain cocks, and build up pressure in the system. SIDE-MOUNTED COMPRESSOR —WITH GAS-ENGINE TRUCKS REMOVAL 1. Drain the cooling system, and open the reservoir drain cocks to exhaust air pressure from the system. 2. Loosen the idler pivot bolt and adjusting bolt, and remove the compressor belt (Fig. 4). 3. At the compressor, disconnect the air outlet line, and the water inlet and outlet lines. 4. Disconnect the reservoir pressure line from the governor. 5. Remove the bracket bolt at the cylinder head and the bracket bolt and washer at the manifold, then remove the bracket between the exhaust manifold and the cylinder head. 6. If equipped with power steering, remove the retaining bolt nut and lock washer from the clip at the frame side rail. Also, remove the power steering hose retaining bolt, nut, and lock washer at the frame crossmember and set the hoses out of the way. 7. Remove the two front compressor to base plate retaining bolts. The clearance between the compressor base plate and the engine mount is very small. 8. Remove the three remaining mounting bolts. 9. Remove the air compressor from underneath the truck in a rearward direction and discard the base INSTALLATION 1. Remove the compressor pulley cotter pin and Woodruff key, then pull the pulley off the shaft with a puller. 2. On C-Series trucks, install the compressor pulley on the replacement compressor at this point. On all other models with a side-mounted compressor, do not install the pulley until after the compressor has been installed in the truck. 3. Transfer the air outlet and the water inlet and.outlet fittings to the

Coat the threads with sealer. 4. Transfer the air inlet strainer and gasket to the replacement compressor (two mounting bolts). Apply sealer. 5. Transfer the governor and gasket to the new compressor (two retaining bolts). Apply sealer. 6. Clean the compressor base and cylinder block base plate (Fig. 5). 7. Apply sealing compound to both sides of base gasket. 8. Install pilot studs in the two rear bolt holes shown in Fig. 5, and position the base gasket to the base plate over the studs. From underneath the truck, mount the compressor to the pilot studs and install three retaining bolts. Remove the pilot studs and install the remaining two bolts. 9. If equipped with power steering, position the power steering hose at the frame cross member and install the clip retainer, bolt, lock washer, and nut. 10. Connect the water outlet line to the compressor. 11. Disconnect the reservoir pressure line at the governor. 12. Position the power steering tube clips at the frame side rail and secure with bolt, lock washer, and retainer nut. 13. Connect the water inlet line to the compressor. 14. On all except C-Series, loosen the two power steering belt adjustment bolts and loosen the belt to provide clearance for installation of the compressor pulley. Install the compressor pulley to the shaft and secure with retainer nut and cotter pin. 15. Position the power steering belt on the pulleys and adjust the belt tension. 16.
