Install drain plug and fill tank with new oil. Install filler cap. Start the engine and operate controls so that all lines are filled. Stop the engine. Check oil level. Add oil as necessary to bring to proper level.
Adjust the valve clearance always when the engine is cold, i.e.: the water temperature should be under 600C (1400F). Initially determine the first cylinder top dead center. For that, turn the engine manually and slowly, using a 1/2 in square wrench and a manual turning device. The valves clearance must be: Intake valves : 0.36 mm (0.014 in) Exhaust valves : 0.46 mm (0.018 in) NOTE: The clearance will be correct when the fealer gauge is passed between the valve rod and the rocker, with a little resistance.
