Methods of adjusting valve clearance of diesel oil pump;

1. Dismantle the cylinder head cover of diesel engine in cold state;

2. Turn the flywheel so that the top dead center line on the flywheel is aligned with the pointer line on the water tank, so that the piston is at the top dead center position of the compression stroke;

3. Measure the clearance between the end of the valve stem and the rocker arm with a thickness gauge. If the thickness gauge cannot be inserted or there is still a big gap after insertion, the valve clearance needs to be adjusted. When the S 195 diesel engine is cold, the intake valve clearance is 0.3 ~ 0.4 mm and the exhaust valve clearance is 0.4 ~ 0.5mm；;

4. Loosen the lock nut of the valve clearance adjusting screw, twist the adjusting screw, measure it with a thickness gauge until the measured value is consistent with the specified value, and tighten the lock nut while keeping the adjusting screw still;

5. When adjusting the gap between the intake valve and the exhaust valve, turn the crankshaft several times, and then measure the gap. If there is any change, it should be readjusted.
