The air starting motor is used to turn the engine flywheel fast enough to get the engine running.
Air Starting System
(1) Starter control valve. (2) Oiler. (3) Relay valve. (4) Air starting motor.The air starting motor is on the right side of the engine. Normally the air for the starting motor is from a storage tank which is filled by an air compressor installed on the left front of the engine. The air storage tank holds 297 liter (10.5 cu ft) of air at 1720 kPa (250 psi) when filled.For engines which do not have heavy loads when starting, the regulator setting is approximately 690 kPa (100 psi). This setting gives a good relationship between cranking speeds fast enough for easy starting and the length of time the air starting motor can turn the engine before the air supply is gone.If the engine has a heavy load which cannot be disconnected during starting, the setting of the air pressure regulating valve needs to be high in order to get high enough speed for easy starting.The air consumption is directly related to speed, the air pressure is related to the effort necessary to turn the engine flywheel. The setting of the air pressure regulator can be up to 1030 kPa (150 psi) if necessary to get the correct cranking speed for a heavily loaded engine. With the correct setting, the air starting motor can turn the heavily loaded engine as fast and as long as it can turn a lightly loaded engine.Other air supplies can be used if they have the correct pressure and volume. For good life of the air starting motor, the supply should be free of dirt and water. The maximum pressure for use in the air starting motor is 1030 kPa (150 psi). Higher pressures can cause problems.
