a. Measure rocker arm inner diameter, diameter should be within .827-.828 inch (21.000-21.033mm).
b. Measure rocker arm shaft diameter, diameter should be within .825-.826 inch (20.959-20.980mm).
c. Subtract shaft diameter from rocker arm inner diameter, maximum clearance should not exceed .004 inch (.10mm).
d. If clearance or diameter is not within specification, replace rocker arm or rocker arm shaft as necessary.
