Camshaft Inspection

Set the No.1 and No.5 journals on V-blocks.
Measure the camshaft runout.
- If it exceeds the specification, replace the camshaft.
Maximum camshaft runout

0.03 mm {0.0012 in}
Measure the cam lobe height at the two points as shown in the figure.
- If it is less than the specification, replace the camshaft.
  
  Fig 1: Measuring Camshaft Runout
Camshaft standard height

IN: 42.44 mm {1.671 in}

EX: 41.18 mm {1.621 in}

Camshaft minimum height

IN: 42.33 mm {1.666 in}

EX: 41.06 mm {1.616 in}
Measure the journal diameters in X and Y directions at the two points (A and B) as indicated in the figure.
- If it is less than the specification, replace the camshaft.
  
  Fig 2: Measuring Cam Lobe Height At Two Points
Camshaft journal standard diameter

24.96-24.98 mm {0.9827-0.9834 in}

Camshaft journal minimum diameter

24.95 mm {0.9822 in}
Remove the tappet.

Position a plastigauge atop the journals in the axial direction.
Install the camshaft cap. (See CYLINDER HEAD ASSEMBLY (II) .)
Remove the camshaft cap. (See CYLINDER HEAD DISASSEMBLY (I) .)
Measure the oil clearance.
- If it exceeds the specification, replace the cylinder head.

Camshaft journal standard oil clearance

0.04-0.08 mm {0.002-0.003 in}

Camshaft journal maximum oil clearance

0.09 mm {0.003 in}
Install the camshaft cap. (See CYLINDER HEAD ASSEMBLY (II) .)
Measure the camshaft end play.
- If it exceeds the specification, replace the cylinder head or camshaft.
Camshaft standard end play

0.09-0.24 mm {0.004-0.009 in}

Camshaft maximum end play

0.25 mm {0.0098 in}
Remove the camshaft cap. (See CYLINDER HEAD DISASSEMBLY (I) .)
