The valve checking fixture is used to re-qualify engine valves after rework. Valve stems can be checked for straightness, minimum diameter and proper length of keeper groove to stem end. Valve head thickness and seat run-out can be measured for both 15 degree and 45 degree valves. Valve head concaveness can also be measured. This fixture is equipped with one each 15 degree and 45 degree head gauges and a .5515 minimum stem diameter master mandrel for zeroing the stem checking gauge.
