C: INSPECTION

1. CAMSHAFT

1) Measure the bend, and repair or replace if nec-
essary.

Limit:

0.025 mm (0.0010 in)

2) Check the journal for damage and wear. Re-
place if faulty.
3) Measure the outside diameter of camshaft jour-
nal and inside diameter of cylinder head journal,
and determine the difference between two (= oil
clearance). If the oil clearance exceeds specifica-
tions, replace the camshaft or cylinder head as
necessary.

4) 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.

Cam height: H

Cam base circle diameter A:

IN: 34.00 mm (1.3386 in)
EX: 34.00 mm (1.3386 in)

2. CAMSHAFT SUPPORT

Measure the thrust clearance of camshaft with dial
gauge. If the clearance exceeds the limit, replace
the camshaft support.

Standard:

0.030 — 0.090 mm (0.0012 — 0.0035 in)

Limit:

0.10 mm (0.0039 in)
