(c) Using a spring tester, measure the tension of the valve
spring at the specified installed length.
Installed tension:
18.6–21.4 kg (41.0–47.2 lb, 182–210 N)
at 33.8 mm (1.331 in.)
If the installed tension is not as specified, replace the valve
spring.
14. INSPECT CAMSHAFTS AND BEARINGS
A.
Inspect camshaft for runout
(a) Place the camshaft on V–blocks.
(b) Using a dial indicator, measure the circle runout at the
center journal.
Maximum circle runout: 0.06 mm (0.0024 in.)
If the circle runout is greater than maximum, replace the cam-
shaft.
B. Inspect cam lobes
Using a micrometer, measure the cam lobe height.
Standard cam lobe height:
Intake 39.510–39.610 mm
(1.5555–1.5594 in.)
Exhaust 38.960–39.060 mm
(1.5339–1.5378 in.)
Minimum cam lobe height:
Intake 39.36 mm (1.5496 in.)
Exhaust 38.81 mm (1.5279 in.)
If the cam lobe height is greater than maximum, replace the
camshaft.
C. Inspect camshaft journals
Using a micrometer, measure the journal diameter.
Journal diameter: 26.949–26.965 mm
(1.0610–1.0616 in.)
If the journal diameter is not as specified, check the oil
clearance.
D. Inspect camshaft bearings
Check the bearings for flaking and scoring.
If the bearings are damaged, replace the bearing caps and
cylinder head as a set.
