Inspect the circle runout.

1. Place the camshaft on V-blocks.
   

2. Using a dial indicator, measure the circle runout at the center journal.
   

   Maximum circle runout:

   0.10 mm (0.00394 in.)
   

   If the circle runout is more than the maximum, replace the camshaft.
   

Using a micrometer, measure the cam lobe height.

Standard Cam Lobe Height:

Cam Lobe	Specified Condition
Intake	54.890 to 54.910 mm (2.1610 to 2.1618 in.)
Exhaust	54.990 to 55.010 mm (2.1650 to 2.1657 in.)

Minimum Cam Lobe Height:

cam Lobe	Specified Condition
Intake	54.39 mm (2.141 in.)
Exhaust	54.49 mm (2.145 in.)

Using a precision straightedge and feeler gauge, measure the surface that contact the cylinder head for warpage.

Maximum warpage:

0.40 mm (0.0157 in.)

Using a precision straightedge and feeler gauge, measure the surface that contact the cylinder head for warpage.

Maximum warpage:

0.40 mm (0.0157 in.)

Using a vernier caliper, measure the minimum outer diameter of the elongated thread at the measuring point.

Standard outer diameter:

11.80 to 12.00 mm (0.465 to 0.472 in.)

Minimum outer diameter:

11.60 mm (0.457 in.)
