CHECKING THE CAMSHAFTS

1. Check:

• Camshaft lobes

Blue discoloration/pitting/scratches

→

Replace the camshaft.

2. Measure:

• Camshaft lobe dimensions “a” and “b”

Out of specification

→

Replace the cam-

shaft.

3. Measure:

• Camshaft runout

Out of specification

→

Replace.

4. Measure:

• Camshaft-journal-to-camshaft-cap clear-

ance
Out of specification

→

Measure the cam-

shaft journal diameter.

▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼

a. Install the camshaft into the cylinder head

(without the dowel pins and camshaft
caps).

b. Position “a” strip of Plastigauge® “1” onto

the camshaft journal as shown.

c. Install the dowel pins and camshaft caps.

NOTE:

• Tighten the camshaft cap bolts in stages and

in a crisscross pattern, working from the
inner caps out.

• Do not turn the camshaft when measuring

the camshaft journal-to-camshaft cap clear-
ance with the Plastigauge®.

d. Remove the camshaft caps and then mea-

sure the width of the Plastigauge® “2”.
