Valve Spring Inspection
1. Inspect the valve springs (1) for pitting, cracks, corrosion and burrs. Replace the springs if necessary
(Figure 13-32, Page 13-18).
2. Measure the free length of the spring. If the measurement is less than the service limit of 1.51 inch
(38.50 mm), replace the spring (Figure 13-32, Page 13-18).
ROCKER ARM AND ROCKER SHAFT INSPECTION
1. Using a dial bore or telescoping gauge, measure the inside diameter of each rocker arm bearing at
several points along its length (Figure 13-33, Page 13-18).
2. If the inside diameter is more than the service limit of 0.4803 inch (12.20 mm), replace the rocker arm.
3. Using a micrometer, measure the diameter of the rocker shaft at several points along its length (Figure
13-34, Page 13-19).
4. If the outside diameter is less than the service limit of 0.4704 inch (11.949 mm), replace the shaft.
