Valve Clearance

Valve clearance is between the cam lobe and cam follower.
Clearance is adjusted by replaceable discs. Discs are available in 26 thicknesses from .119-.166" (3.0-4.25 mm). Discs most frequently used are .140-.150" (3.55-3.80 mm).
To adjust, warm engine to normal operating temperature. Using wrench on center bolt of crankshaft pulley, hand turn crankshaft clockwise until cam lobes for cylinder being tested are pointing upward. Use feeler gauge to check valve clearance.
Use special depressor tool (2078) to press down cam follower, so that adjusting disc can be readily removed with special pliers (US 4476). When depressing cam followers, turn so that openings are at a 90° angle to cam.
