Valve Inspection
1. Remove all carbon from valves with a soft wire wheel or
brush.
2. Check valve face for runout, pitting, and burnt spots. To
check for bent valve stems, mount valve in a drill or use “V”
blocks and a dial indicator.
3. Check end of valve stem for flaring, pitting, wear or damage
(A).
4. Inspect split keeper groove for wear or flaring of the keeper
seat area (B).
NOTE: The valves can be re-faced or end ground, if
necessary. They must be replaced if extensively
worn, burnt, bent, or damaged.
5. Measure diameter of valve stem with a micrometer in three
places, then rotate 90 degrees and measure again (six
measurements total). Compare to specifications.
6. Measure valve guide (C) inside diameter at the top middle
and end of the guide using a small hole gauge and a
micrometer. Measure in two directions.
7. Subtract valve stem measurement from the valve guide
measurement to obtain stem to guide clearance. NOTE:
The valve guides cannot be replaced. Be sure to measure
each guide and valve combination individually.
