MAINTENANCE DESCRIPTION
Check solenoid and motor for corrosion. Remove
and lubricate. Clean and lubricate the starter motor
pinion drive.
Check ignition timing. Check condition of distributor
cap and rotor.
Incorrect valve clearance will result in poor engine
performance, check compression pressure and
timing and adjust valve clearances.
Remove and replace every 1000 hours.
NOTE: Failure to replace the timing belt at the
recommended inteNal could result in timing chain
failure resulting in major damage to the engine.
Test exhaust elbow for casting integrity. Replace if
casting is corroded or deteriorated.
NOTE: A defective exhaust elbow can cause
carbon monoxide leakage!
Remove water injected exhaust elbow and visually
inspect. Replace every 2000 hours.
Perform back pressure test to ensure system is not
developing restrictions that will increase pressure
above 1.5 PSI or 41 inches of water column at full
operating amperage load. Correct as needed.
Remove water injected exhaust elbow and visually
inspect every 2000 hours. Replace as needed.
Inspect every 1000 hours. Replace every 2000 hours.
Sample with CO analyzer.
