Valve: Testing and Inspection
Stem to Guide Clearance
NOTE: Valve stem diameter must be within specifications before checking valve stem to valve guide clearance.
1. Install a Valve Stem Clearance Tool on the valve stem and install a Dial Indicator with Bracketry. Lower the valve until the Valve Stem Clearance
Tool contacts the upper surface of the valve guide.
NOTE: If necessary, use a magnetic base.
2. Move the Valve Stem Clearance Tool toward the indicator and zero the indicator. Move the Valve Stem Clearance Tool away from the indicator
and note the reading. The reading will be double the valve stem-to-valve guide clearance. Valves with oversize stems will need to be installed if
out of specification.
