You must read and understand the warnings and instructions contained in the Safety section of this manual before performing any operation or maintenance procedures.Valve Lash
Check/Adjust
Initial valve lash adjustment is recommended within the first and forth scheduled oil change intervals due to initial wear and seating of valve train components.Subsequent adjustments should be made at the Every 2000 Hour interval.This maintenance is recommended by Caterpillar as part of a lubrication and preventive maintenance schedule to provide maximum engine life.
Operation of Caterpillar engines with improper valve adjustments will reduce engine efficiency. This reduced efficiency could result in excessive fuel usage and/or shortened engine component life.
Only qualified service personnel should perform this maintenance. Refer to the Service Manual or your Caterpillar dealer for the complete valve lash adjustment procedure.
Be sure the engine cannot be started while this maintenance is being performed. To prevent possible injury, do not use the starting motor to turn the flywheel.Hot engine components can cause burns. Allow additional time for the engine to cool before measuring/adjusting valve lash clearance.
Valve Rotators
When inspecting the valve rotators, protective glasses or face shield and protective clothing must be worn, to prevent being burned by hot oil or spray.
If a damaged rotator is not replaced, valve face guttering could result in pieces of the valve to fall into the cylinder. This can cause piston and cylinder head damage.
Refer to the Service Manual for the valve rotator inspection procedure.Fuel Ratio Control, Set Point, and Low Idle
Check/Adjust
This maintenance should be performed intially after the First 1000 Hours or Six Months of operation, whichever comes first.Subsequent check/adjustments should be made at the Every 2000 Hour interval.The fuel ratio control limits the amount of fuel to the cylinders during acceleration. This affects the amount of exhaust smoke. The set point check is a method for diagnosing engine performance. Slow engine response and low power indicate that a fuel control adjustment or repair is necessary.
Adjustments and repairs should be made by an authorized Caterpillar dealer.
The fuel ratio control, set point, and idle speed checking and adjusting should only be performed by Caterpillar authorized service personnel. Consult with your Caterpillar dealer for assistance. Authorized Caterpillar dealers are equipped to properly perform these services.Fuel Injection Nozzles
Test/Exchange
Fuel injection nozzles are subject of tip wear. Tip wear, a result of fuel contamination, can cause:* increased fuel consumption* black smoke* misfire* rough runningNozzles should be cleaned, inspected, tested, and replaced if necessary. Refer to Special Instruction SEHS7292, for using the 8S-2245 Nozzle Cleaning Kit. Consult with your Caterpillar dealer about nozzle cleaning and testing.
Never wire brush or scrape a nozzle. Wire brushing or scraping a nozzle will damage the finely machined orifice. Proper tools for cleaning and testing nozzles can be obtained from authorized Caterpillar dealers.
Abnormal engine running, smoke emission, and engine knock can be symptoms of nozzle malfunction. Each nozzle must be isolated one at a time in order to determine the malfunction nozzle.1. Start the engine.
A nozzle will be damaged if the top of the nozzle turns in the
