Rocker Arm Assembly: Testing and Inspection
ROCKER SHAFT AND ROCKER ARM
1. Check rocker shafts for scratches, seizure and wear.
2. Check outer diameter of rocker shaft. The diameter is 17.979 - 18.000 mm (0.7078 - 0.7087 inch.)
3. Check inner diameter of rocker arm. The diameter is 18.007 - 18.028 mm (0.7089 - 0.7098 inch). The rocker arm to shaft clearance is equal to the
inner diameter of rocker arm minus the outer diameter of rocker shaft is 0.007 - 0.049 mm (0.0003 - 0.0019 inch.)

arm inner diameter.
