ROCKER ARM AND ROCKER SHAFT INSPECTION
1. Using a telescoping gauge, measure the inside diameter of each rocker arm bearing at several points
along its length. If the inside diameter is more than the service limit of 0.4754 inch (12.075 mm),
replace the rocker arm (Figure 13-32, Page 13-18).
2. Using a micrometer, measure the outside diameter of the rocker shaft at several points along its length
(Figure 13-33, Page 13-19). If the outside diameter is less than the service limit of 0.4704 inch (11.949
mm), replace the shaft.
PUSH ROD INSPECTION
1. Support the rod in V-blocks at each end of rod. Position a dial gauge perpendicular to the rod (Figure 13-34,
Page 13-19).
2. Turn the rod slowly and read the variation on the gauge.
3. If the push rod is bent more than 0.012 inch (0.3 mm), replace the push rod.
