5. Support the rocker arm shaft on V-blocks at its
ends and check the amount of run-out at the
center part using a dial indicator. If a slight amount
of run-out is noticeable, correct with a bench press
without applying heat. Replace the rocker arm
shaft if the amount of run-out is 0.3 mm (.012 in).
6. Measure the diameter of the rocker shaft at both of
the rocker arm locations. The diameter must be
23.959 to 23.978 mm (.9432 to .9440 in).
NOTE : The maximum permissible clearance
between the rocker arm bearings and shaft is 0.25
mm (.0099 in.).

1. If replacement was needed, make an alignment of
oil hole in the bushing with the oil hole in the rocker
arm. Install new bushing (7) in the rocker arm with
tool (A) and a press.
NOTE : Check the bore dimension of the bushing in
the rocker arm after installation. It must be within the
tolerance given in the specifications.
Do not turn the adjusting screw too far into the rocker
arms. Damage to the valve can be the result after the
rocker shaft and push rods have been installed in the
engine.
2. Install adjusting screw (6) and nut (5) in the rocker
arm.
