After letting the #1 cylinder’s piston come at the compression top dead center by turning the crankshaft, adjust the valve clearances. Loosen the lock nuts of rocker arm adjusting screws and push the feeler gauge of specified value between a rocker arm and a valve stem and adjust the clearance with adjusting screw respectively and then tighten with the lock nut. As for the valve clearance, adjust it when in cold, as follow. Exhaust Valve 0.3 mm - By cranking the engine, let #6 cylinder’s valves overlap. - In time, adjust the valve clearance corresponding to “ “ of lower figure. - Rotating the crankshaft by one revolution, #6 cylinder become the compression state of top dead center.
- After reinsuring the valve clearances, retighten if necessary. No. 1 Cylinder is located at the side where flywheel was installed. - Adjust the valve clearance corresponding to “ “ of lower figure.
