What is the adjustment method for valve clearance in a single-cylinder diesel engine?

[LailaDella]

The adjustment method for valve clearance in a single-cylinder diesel engine is as follows: 1. Remove the cylinder head cover when the engine is cold; 2. Rotate the flywheel to align the top dead center mark on the flywheel with the pointer mark on the radiator, positioning the piston at the top dead center of the compression stroke; 3. Measure the clearance between the end of the valve stem and the rocker arm. If a feeler gauge cannot be inserted or there is still a significant gap after insertion, the valve clearance needs to be adjusted; 4. Loosen the lock nut of the valve clearance adjustment screw, turn the adjustment screw, and measure with a feeler gauge until the measured value matches the specified value. While keeping the adjustment screw stationary, tighten the nut.
