Pressure Regulating Valve
PRESSURE REGULATING VALVE (Typical Illustration)
1. Adjustment screw. 2. Regulator inlet. 3. Regulator outlet.To check and adjust the pressure regulating valve, use the procedure that follows:1. Drain the line to the pressure regulating valve or drain the air storage tank.2. Disconnect the regulator from the starter control valve.3. Connect an 8M2885 Pressure Gauge to regulator outlet (3).4. Put air pressure in the line or tank.5. Check the pressure.6. Adjust the pressure regulating valve as shown in Chart For Air Pressure Setting.7. Remove the air pressure from the line or tank.8. Remove the 8M2885 Pressure Gauge and connect the air pressure regulator to the line to the air starter motor.Each engine application will have to be inspected to get the most acceptable starting results. Some of the factors that affect regulating valve pressure setting are: attachment loads pulled by engine during starting, ambient temperature conditions, oil viscosity, capacity of air reservoir, and condition of engine (new or worn). The advantage of setting the valve at the higher pressures is increased torque for starter motor and faster rotation of engine. The advantage of setting the valve at the lower pressures is longer time of engine rotation for a given capacity of supply air.Lubrication
Always use an air line lubricator with these air starter motors.For temperatures above 0°C (32°F), use a good quality SAE 10 motor oil.For temperatures below 0°C (32°F), use diesel fuel.To maintain the efficiency of the starter motor, flush it at regular intervals. Pour approximately 0.5 liter (1 pt.) of diesel fuel into the air inlet of the starter motor and operate the motor. This will remove the dirt, water and oil mixture (gummy coating) from the vanes of the motor.Air Starting Motor
The cylinder (12) must be assembled over the rotor (15) and on the front end plate (16) so the dowel hole (12A) and the inlet passages (12B) for the air are as shown in the rear view illustration of the cylinder and rotor. If the installation is not correct, the starter drive (42) will turn in the wrong direction.
