E: INSPECTION
1. VALVE ROCKER ARM AND ROCKER
SHAFT
1) Measure the inside diameter of valve rocker arm
and outside diameter of valve rocker shaft, and de-
termine the difference between the two (= oil clear-
ance).
Clearance between arm and shaft:
Standard
0.020 — 0.054 mm (0.0008 — 0.0021 in)
Limit
0.10 mm (0.0039 in)
2) If oil clearance exceeds the limit, replace the
valve rocker arm or shaft, whichever shows greater
amount of wear.
Rocker arm inside diameter:
22.020 — 22.041 mm (0.8669 — 0.8678 in)
Rocker shaft diameter:
21.987 — 22.000 mm (0.8656 — 0.8661 in)
3) If cam or valve contact surface of valve rocker
arm is worn or dented excessively, replace the
valve rocker arm.
4) Check that the valve rocker arm roller rotates
smoothly. If not, replace the valve rocker arm.
