Use the N14 valve head checking tool to measure the

head thickness of the valves.

NOTE: Install the valve on the tool with the valve head

contacting the tool as shown. If the valve head is even with,

or extends beyond the end of the tool, the valve can be

reground. If the valve head is below the end of the tool, the

valve is not thick enough for regrinding.

If a valve head checking tool is not available after re-

grinding the valve seat surface, put the valve on a flat

surface and measure the head thickness (1) at the outside

diameter.

[0.50-inch] from each end (1) and at the center as shown.
