INSPECTION

CAMSHAFT





Measure camshaft height (camshaft major axis). If the height is less than the limit, replace the camshaft.
Standard value:

Intake: 44.1 mm (1.74 inches)
Exhaust: 45.0 mm (1.77 inches)
Limit:

Intake: 43.6 mm (1.72 inches)
Exhaust: 44.5 mm (1.75 inches)


CAMSHAFT OIL CLEARANCE (PLASTIGAGE METHOD)

1. Thoroughly wipe oil on the outside diameter of the camshaft and the inside diameter of the bearing.

2. Install the bearing to the camshaft.





3. Put straightly the plastigage having the length of the bearing width on the journal axis, centering the axis.
4. Carefully install the bearing cap.Tighten the bolt as instructed in ]]B[[ Bolt Installation Point.
5. Remove the bolt and the bearing cap carefully.





6. Measure the plastigage whose width is most compressed using the scale printed on the plastigage bag. When the measured value deviates from the standard one, replace the bearing.
Standard value: 0.035 - 0.072 mm (0.0014 - 0.0028 inch)

CAUTION:
When the bearing is used again, be careful not to reverse the cylinder head side and the camshaft side during installation.

VALVE TAPPET





1. Measure the valve tappet at the illustrated position. If the measured value is not in agreement with the value in the table corresponding to the identification mark, replace the valve tappet.





2. The valve tappet has an identification mark and stamping of thickness at illustrated positions.
There are 47 kinds of valve tappets at intervals of 0.015 mm (0.0006 inch) in the range between 3.000 mm (0.1181 inch) and 3.690 mm (0.1453 inch).
