Camshaft

Inspection (cont'd)

3. Zero the dial indicator against the rear end of the

camshaft. Push the camshaft back and forth, and

read the end play.

Camshaft End Play:

Standard (New): 0.05 - 0.15 mm

(0.002 - 0.006 in)

Service Limit: 0.15 mm (0.006 in)

4. Remove the bolts, then remove the camshaft hold-

ers from the cylinder head.

5. Lift the camshaft out of the cylinder head, wipe it

clean,
then
inspect
the
lift
ramps.
Replace
the

camshaft if any lobes are pitted, scored, or excessive-

ly worn.

6. Clean the camshaft bearing surfaces in the cylinder

head, then set the camshaft back in place.

7. Insert a plastigage strip across each journal.

8. Install the camshaft holders, then tighten the bolts

to the specified torque shown on the previous page.

9. Remove the camshaft holders. Measure the widest

portion of plastigage on each journal.

Camshaft-to-Holder Oil Clearance:

Standard (New): 0.050 - 0.089 mm

(0.0020 - 0.0035 in)

Service Limit: 0.10 mm (0.004 in)

PLASTIGAGE STRIP
10.

If camshaft-to-holder oil clearance is out of toler-

ance:

— And the camshaft has already been replaced,

you must replace the cylinder head.

— If the camshaft has not been replaced, first check

the total runout with the camshaft supported on

V-blocks.

Camshaft Total Runout:

Standard (New): 0.03 mm (0.001 in) max.

Service Limit: 0.04 mm (0.002 in)

Rotate camshaft

while measuring.

— If the total runout of the camshaft is within toler-

ance, replace the cylinder head.

— If the total runout is out of tolerance, replace the

camshaft and recheck. If the oil clearance is still

out of tolerance, replace the cylinder head.

11. Check cam lobe height wear.

Cam Lobe Height Standard (New):

INTAKE 40.005 mm (1.5750 in)

EXHAUST 37.766 mm (1.4868 in)

Check this area for wear.
