Visually inspect the rocker lever contact pad for wear, cracks, or damage.
Visually inspect the valve stem contact areas for damage.
Measure both valve stem pocket depths from the valve stem pocket to the rocker pad face (1).
On a given crosshead, the stem pocket to pad bore dimension (1) on one end must fall to within 0.020 inch of
the dimension (2) on the opposite end.
In a cylinder head assembly, the crosshead to valve spring retainer must be a minimum of 0.020 inch.
NOTE: If damaged parts are found or if the stem bore or pocket depth are not within the limits specified, the parts
must be replaced. If cracks are suspected, refer to Valve Crosshead – Magnetic Crack Inspection (02-13).
