Pressure regulating valve
(1) Adjustment screw. (2) Regulator inlet. (3) Regulator outlet.
Check and adjust the pressure regulating valve by using the following procedure:
Drain the line to the pressure regulating valve or drain the air storage tank.
Disconnect the regulator from the starter control valve.
Connect the 8T-0849 Pressure Gauge Group to the regulator outlet (3).
Put air pressure in the line or the tank.
Check the pressure.
Adjust the pressure regulating valve to the value that is shown for the Recommended Air Pressure Setting.
Remove the air pressure from the line or the tank.
Remove the 8T-0849 Pressure Gauge Group and connect the air pressure regulator to the line to the air starting motor. Each engine application must be inspected to provide the most acceptable starting results. The following factors affect the settings for the pressure regulating valve:attachment loads pulled by the engine during starting, ambient temperature conditions, oil viscosity, capacity of air reservoir and condition of the engine (new or worn).

Chart For Air Pressure Setting
Motor Minimum Maximum
Ingersoll-Rand kPa 690 1030
Psi 100 150 The advantage of setting the valve at the higher pressures is the increased torque for the starting motor and the faster rotation of the engine. The advantage of setting the valve at the lower pressures is the longer time of the engine rotation for the given reservoir capacity of the supply air.Lubrication
Always use an air line lubricator with the air starting motors that have vanes.For temperatures above 0°C (32°F), use a good quality nondetergent SAE 10 weight motor oil.For temperatures below 0°C (32°F), use air tool oil. To maintain the efficiency of the starting motor, flush the starting motor at regular intervals. Pour approximately 0.5 L (1 pt) of diesel fuel into the air inlet of the starting motor and operate the starting motor. This procedure will remove the following items from the vanes of the air starting motor.

(12) Cylinder. (12A) Air inlet passages. (12B) Dowel hole. (15) Rotor.
The cylinder (12) must be assembled over the rotor (15) and on the front end plate (16). The dowel hole (12A) and the inlet passages (12B) for the air are shown in the rear view illustration of the cylinder and the rotor. If the installation is not correct, the starter drive (42) will turn in the wrong direction.Tighten the bolts (6) of the rear cover in small increases of torque. Tighten all bolts until the bolts are tight 25 to 35 N m (18 to 25 lb ft).

Apply a thin layer of lubricant on the lip of the seal (29) and on the outside of the collar (35). This lubricant is for the installation of the drive shaft (34). After the installation of the shaft through the cover (28), check the lip of the grease seal (29). The lip of the grease seal must be turned correctly toward the drive gear (25). If the shaft turned the seal lip in the wrong direction, remove the shaft and install the shaft again. Use a tool with a thin point to turn the seal lip in the correct direction.Tighten the bolts (32) of the drive housing in small increases of torque.Tighten the bolts to the following torque. ... 11.3 N m (100 lb in)Check the motor for the correct operation. Connect an air hose to the motor inlet (49). Turn the motor slowly. Look at the drive pinion (42) from the front of the drive housing (45). The pinion must turn clockwise.Connect an air hose to the small hole with the threads. This hole is in the drive housing (45). The hole is closer to the gear case (22). When a little air pressure goes to the drive housing, the drive pinion (42) must move forward to the engaged position. Also, the air must get out through the other hole with threads. This hole is located closer to the mounting flange (51).
