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.Bevel Gear Compartment
