Valve Stem to Guide Clearance

Special Tools:

Note: The valve stem diameter must be within specification before checking valve stem-to-valve guide clearance.

1. Install the Valve Stem Clearance Tool on the valve stem and install Dial Indicator With Bracketry. Lower the valve until the Valve Stem Clearance Tool contacts the upper surface of the valve guide.





2. Move the Valve Stem Clearance Tool toward the Dial Indicator and zero the Dial Indicator. Move the Valve Stem Clearance Tool away from the Dial Indicator and note the reading. The reading will be double the valve stem-to-valve guide clearance. Verify clearance is within specification.
