Adjust
To prevent possible injury, do not use the starter motor to turn the flywheel.Hot engine components can cause burns. Allow additional time for the engine to cool before measuring valve clearance.
Measure the valve lash with the engine stopped. To obtain an accurate measurement, allow at least 20 minutes for the valves to cool to engine cylinder head and block temperature.
Adjust the valve clearance to within 0.08 mm (.003 in) of the valve clearance setting given in the chart. Refer to the Service Manual or your Caterpillar dealer for the complete valve adjustment procedure.Engine Valve Rotators
Check
When inspecting the valve rotators, protective glasses or face shield and protective clothing must be worn, to prevent being burned by hot oil spray.
1. Start the engine and run at low idle. 2. Watch the top surface on each valve rotator. Each valve rotator should turn slightly each time the valve closes.3. Stop the engine.If a valve fails to rotate, contact your Caterpillar dealer.Track Roller Frame Guides
