C: INSPECTION
1) Measure the bend, and repair or replace if nec-
essary.
Limit:
0.020 mm (0.0008 in)
2) Check the journal for damage and wear. Re-
place if faulty.
3) Measure the outside diameter of camshaft jour-
nal. If the journal diameter is not as specified,
check the oil clearance.
4) Measurement of the camshaft journal oil clear-
ance:
(1) Clean the bearing caps and camshaft jour-
nals.
(2) Place the camshafts on cylinder head.
(Without installing the valve rocker.)
(3) Place a plastigage across each of the cam-
shaft journals.
(4) Gradually tighten the cap in at least two
stages in alphabetical sequence shown in the
figure, and then tighten to specified torque.
Do not turn the camshaft.

(5) Remove the bearing caps.
(6) Measure the widest point of plastigage 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:
0.037 — 0.072 mm (0.0015 — 0.0028 in)
Limit:
0.10 mm (0.0039 in)
(7) Completely remove the plastigage.
5) Check the cam face condition; remove the minor
faults by grinding with oil stone. Measure the cam
height H, replace if the limit has been exceeded.

Cylinder Head Assembly
1) Installation of valve spring and valve.
(1) Coat the stem of each valve with engine oil
and insert the valve into valve guide.
NOTE:
When inserting the valve into valve guide, use spe-
cial care not to damage the oil seal lip.
(2) Set the cylinder head on ST1.
(3) Install the valve spring and retainer using
ST2.
ST1 498267600 CYLINDER HEAD TABLE
ST2 499718000 VALVE SPRING REMOVER
NOTE:
Be sure to install the valve springs with their close-
coiled end facing the seat on cylinder head.
(4) Compress the valve spring, and then fit the
valve spring retainer key.
(5) After installing, tap the valve spring retainers
lightly with wooden hammer for better seating.
2) Apply oil to the surface of the valve lifter.
3) Install the valve lifter.
E: INSPECTION
1. CYLINDER HEAD
1) Make sure that no crack or other damage exists.
In addition to visual inspection, inspect the impor-
tant areas by means of red check.
2) Measure the warping of the cylinder head sur-
face that mates with crankcase by using a straight
edge (A) and thickness gauge (B).
If the warping exceeds 0.05 mm (0.0020 in), re-
grind the surface with a surface grinder.
Warping limit:
0.05 mm (0.0020 in)
Grinding limit:
0.3 mm (0.012 in)
Standard height of cylinder head:
127.5 mm (5.02 in)NOTE:
Uneven torque for the cylinder head nuts can
cause warping. When reassembling, pay special
attention to the torque so as to tighten evenly.
2. VALVE SEAT
Inspect the intake and exhaust valve seats, and
then correct the contact surfaces with valve seat
cutter if they are defective or when valve guides are
replaced.
