25. Use a J 8001 with a J 26900-13 in order to measure the rocker arm shaft (1) runout.
1. Place the rocker arm shaft (1) between two V-blocks and rotate slowly while measuring the runout. The maximum rocker-arm shaft runout is
0.20 mm (0.008 in).
2. Replace the rocker arm shaft if the rocker arm shaft runout exceeds 0.20 mm (0.008 in).
26. Use the J 26900-1 and a telescopic micrometer in order to measure the rocker arm-to-rocker arm shaft clearance.
1. Use the J 26900-1 in order to measure the outside diameter of the rocker arm shaft (1). The standard rocker arm outside diameter 15.969 to
15.984 mm (0.6287 to 0.6293 in).
2. Use a telescopic micrometer in order to measure the inside diameter of the rocker arms. The standard rocker arm inside diameter is 15.985 to
16.005 mm (0.629 to 0.630 in).
27. Subtract the outside diameter measurement of the rocker arm shaft from the inside diameter measurement of the rocker arms to determine the
rocker arm-to-rocker arm shaft clearance.
