4.4 Regular operation Practice the daily inspection and maintenance for trouble free, safe and reliable engine performance (refer table 4.1) DAILY INSPECTION AND MAINTENANCE BEFORE START UP ► Ensure oil level is correct. ► Ensure coolant level is correct. ► Ensure sufficient fuel level in the fuel tank. ► Drain out water and impurities from fuel water separator and filter respectively ► Ensure the belt tightness is sufficient, and that there is no crack, peel off etc. ► Ensure no leakage from any of the fluid systems – coolant, oil, fuel, etc. ► Ensure all electrical control system is in order and ensures the battery is healthy.
► Ensure all the hoses are free from leakage, not developed any cracks, etc. ► Ensure sufficient greasing wherever required (water pump, belt tensioner pulley etc.). AFTER STARTING ► Keep the engine on idle speed for 2 -3 minutes and let it warm up. ► Ensure no leakage in the fluid system – Coolant, oil etc. ► Observe the oil pressure, oil temperature, coolant temperature are normal. ► Observe the engine operation and ensure no abnormal noise, vibration, etc. ► Observe the exhaust smoke is normal. ► Ensure no variation in engine speed (hunting etc.) Table 4.1 Record basic engine parameter during early life of the engine. Monitor it every routine inspection and maintenance.
Gradual drop in oil pressure is the indicator of progressive wear in inter-nal parts. If any abnormal change in parameter is noticed, shutdown the engine immediately. Find out and rectify the cause of trouble before restart. Refer table 4.2 for specified fit and clear- ance values 20
