Check the structural integrity of the water injected exhaust elbow casting. Check the integrity
of the exhaust system attached to the elbow. All hose connections should be secure. No
chaffing. No exhaust leaks. Hoses and muffler are in good serviceable condition.
NOTE: An exhaust leak will cause exposure to diesel exhaust!
Check and adjust injection opening pressure and spray conditions.
Drain, flush and re-fill the cooling system with appropriate antifreeze mix. Replace the
thermostat and cooling pressure cap.
Adjust valves. (Incorrect valve clearance will result in poor engine performance)
Che.ck solenoid and motor for corrosion. Remove and lubricate. Clean and lubricate the starter
motor pinion drive.

antifreeze and flush the system.
Adjust the valves.
Disassemble and clean.
Pressure test injectors/re-build at 1500 hours.
Remove, inspect casting, clean and replace as needed.
Inspect the damper plate, replace if necessary (damper plate chatter at idle speed is an
indication of damper spring wear).
WARNING:
Never attempt to perform any service while the unit is operating. Wear the proper safety equipment such as goggles
and gloves, and use the correct tools for each type of maintenance performed. Shut OFF the control panel's DC breaker when
servicing any of the engines DC electrical components. ·
