ENGINE
Standard camshaft thrust clearance:
Intake :0 .03 - 0 .09 mm (0 .0012 - 0.0035 in)
Wear limit
0.13 mm (0.0051 in)
Exhaust:0.02 - 0.08 mm (0 .0008 - 0.0031 in)
Wear limit
0.12 mm (0.0047 in)
(3) If the thrust clearance exceeds the limit, replace
the camshaft caps and cylinder head as a set. If
necessary, replace the camshaft .
7) Measurement of the camshaft journal oil clearance
(1) Clean the bearing caps and camshaft journals .
(2) Place the camshafts on the cylinder head . (With-
out installing lash adjuster .)
(3) Place plastigauge across each of the camshaft
journals .
(4) Install the bearing caps .
(Refer to CW3E1].)
Do not turn the camshaft .
(5) Remove the bearing caps .
(6) Measure the widest point of the plastigauge on
each journal .
If the oil clearance exceeds the limit, replace the
camshaft . If necessary, replace the camshaft caps
and cylinder head as a set .
Standard oil clearance:
0.037 - 0.072 mm (0 .0015 - 0.0028 in)
Limit:
0.10 mm (0.0039 in)
Fig . 58
(7) Completely remove the plastigauge .
2. CAMSHAFT GEAR
1) Inspection of camshaft gear backlash .
(1) Install the intake and exhaust camshafts without
installing hydraulic lash adjusters .
(Refer to [W3E1] .)
Do not install the intake camshaft sub-gear.
(2) Measure the backlash using dial gauge. If the
backlash exceeds the limit, replace the intake and
exhaust camshafts as a set.
Standard camshaft gear backlash :
0.029 - 0.175 mm (0.0011 - 0 .0069 in)
Limit :
0.30 mm (0.0118 in)
Hg. 59
2) Measure the free distance between the camshaft
gear spring ends .
If the free distance is not as specified, replace the gear
spring .
Free distance :
24.88 - 28.88 mm (0 .9795 - 1.1370 in)
