How to Adjust Engine Valve Clearance?
1 Answers
There are several methods for adjusting valve clearance: 1. Rotate the crankshaft to locate the compression top dead center of the cylinder. 2. First, check if the valve clearance is appropriate. If not, loosen the intake and exhaust valve adjusting screw lock nuts of the cylinder, then loosen the adjusting screw. 3. Insert a feeler gauge with the correct valve clearance value between the tail of the valve stem and the head of the valve rocker arm. While turning the adjusting screw, pull the feeler gauge until you feel slight resistance. 4. Adjust the intake and exhaust valve clearances of other cylinders to the standard value using the same method.
