- Measure the rocker arm
shaft outside diameter where the rocker arm is located. The production value
is 21.979-22.0 mm (0.8653-0.8661 in) and the service
limit is 21.85 mm (0.8602 in).
- Replace the rocker arm shaft if the measured value is less than
the service limit.
- Measure the rocker arm inside diameter.
The production value is 22.01-22.035 mm (0.8665-0.8675 in).
- Calculate the rocker arm shaft to rocker arm clearance.
| 4.1. | Subtract the rocker arm shaft outside diameter from the rocker
arm inside diameter. |
| 4.2. | Replace the rocker arm if the rocker arm shaft to rocker arm clearance
is over 0.2 mm (0.0079 in). |
- Inspect the valve lash adjusting screw and lock nut for damage.
Replace the valve lash adjusting screw if any damage is found.
