SERIES 60 ON-HIGHWAY ENGINE OPERATOR'S GUIDE should be made to determine the cause. check the lubrication system. The pressure should not drop below 28 psi or 193 kPa at 1800 rpm, and normal operating pressure should be higher. If oil pressure does not fall within these guidelines, it should be checked with a manual gage. Air Starter — Because of the limited volume of most compressed air storage tanks and the relatively short duration of the cranking cycle, it is important to make sure the engine is ready to start before activating the air starter. Start an engine equipped with an air starter as follows: HOT OIL 1. Check the pressure in the air storage tank.
If necessary, add air to bring the pressure up to at least the recommended minimum for starting. To avoid injury from hot oil, do not operate the engine with the rocker cover(s) removed. 2. With foot OFF the foot pedal, press the starter button firmly and hold until the engine starts. Warm-up Run the engine at part throttle for about five minutes to allow it to warm up before applying a load. Running the Engine While the engine is operating, monitor the battery charge indicator light, the oil pressure and avoid excessive idling. Inspection While the engine is idling, inspect the transmission, check for fluid leaks, check the crankcase and turbocharger.
Oil Pressure Transmission While the engine is idling, check the automatic transmission (if equipped) for proper oil level and add oil as required. Observe the oil pressure gage immediately after starting the engine. A good indicator that all moving parts are getting lubrication is when the oil pressure gage registers pressure (5 psi or 35 kPa at idle speed). If no pressure is indicated within 10 to 15 seconds, stop the engine and Fluid Leaks Look for coolant, fuel or lubricating oil leaks. If any are found, shut down the engine immediately and have the leaks repaired after the engine has cooled. All information subject to change without notice.
