Adjust the valves on a Kawasaki tractor engine by removing the valve cover to access the valve adjustment screw and checking the valve clearances.

Full Answer

To initiate valve adjustment, remove the spark plug using the socket and box wrench. Then, remove the bolts that hold the valve cover in place. Gently tap the cover on the side using a rubber mallet to pop it from its housing.

Spin the engine by the flywheel so that the cylinder is at the top dead center position. The piston is at this position during the compression stroke, which closes the intake valve. The upper valve is the intake and the lower valve is the exhaust.

To make the adjustment, use the box wrench to loosen the valve adjuster lock to release the adjustment screw. Check the valve clearances with the feeler gauge, and set them to the recommended manufacturer’s settings by turning the Allen wrench on the adjustment screw. Then, tighten the adjuster lock. Once the nut is tight enough, you can replace the valve cover.
