VALVE SPRING SQUARENESS
Set try square (A) along the side of the valve spring and rotate the
spring. Measure the maximum clearance between the top face of the
spring and the try square.
CAUTION:
Do not remove the valve spring seat from the valve spring
NOTE:
If the valve spring exceeds the limi t, replace the valve spring with the
valve spring seat.
VALVE SPRING DIMENSIONS AND VALVE SPRING PRESSURE LOAD
Check valve spring pressure with valve spring seat installed at spec-
ified spring height. Replace if not within specifications.
CAUTION:
Do not remove the valve spring seat.

CYLINDER BLOCK
Method of Using Plastigage
• Remove oil and dust on the crankshaft journal and the surfaces of
each bearing completely.
• Cut the Plastigage slightly shorter than the bearing width, and
place it in crankshaft axial direction, avoiding oil holes.
• Tighten the main bearing bolts to the specified torque. CAUTION:
Do not rotate the crankshaft.
• Remove the bearing cap and bearings, and using the scale on the Plastigage bag, measure the Plastigage width.
NOTE:
The procedure when the measured value exceeds the limit is
same as that described in the "Method by Calculation".
CRUSH HEIGHT OF MAIN BEARING
• When the bearing cap is removed after being tightened to the specified torque with main bearings installed, the tip end of bearing
must protrude.
• If the standard is not met, replace main bearings.
OUTER DIAMETER OF LOWER CYLINDER BLOCK BOLT
• Perform only with M10 (0.39 in) bolts.
• Measure outer diameters (d1, d2) at two positions as shown.
• Measure d2 at a point within area (A) as shown.
• When the value of d1- d2 exceeds the limit (a large difference in dimensions), replace the bolt with a new one.
OUTER DIAMETER OF CONNECTING ROD BOLT
• Measure outer diameter (d) at position as shown.
• When (d) exceeds the limit (when it becomes thinner), replace the
bolt with a new one.
