Remove lower cylinder block and bearings, and using scale on
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 lower cylinder block is removed after being tightened to
the specified torque with main bearings installed, the tip end of
bearing must protrude. Refer to 

EM-112, "ASSEMBLY"

  for the

tightening procedure.

If the standard is not met, replace main bearings.

CRUSH HEIGHT OF CONNECTING ROD BEARING

When connecting rod bearing cap is removed after being tight-
ened to the specified torque with connecting rod bearings
installed, the tip end of bearing must protrude. Refer to 

EM-112,

"ASSEMBLY"

  for the tightening procedure.

If the standard is not met, replace connecting rod bearings.

LOWER CYLINDER BLOCK BOLT OUTER DIAMETER

Measure the outer diameters (“d

1

 ”, “d

2

 ”) at two positions as

shown.

If reduction appears in “A” range, regard it as “d

2

 ”.

If it exceeds the limit (large difference in dimensions), replace
lower cylinder block bolt with new one.

CONNECTING ROD BOLT OUTER DIAMETER

Measure the outer diameter “d” at position shown.

If the reduction appears in a position other than “d”, regard it as
“d”.

When “d” exceeds the limit (when it becomes thinner), replace
connecting rod bolt with new one.

DRIVE PLATE 

Check drive plate and signal plate for deformation or cracks.

CAUTION:

Do not disassemble drive plate.

Do not place drive plate with signal plate facing down.

When handling signal plate, take care not to damage or
scratch it. 

Handle signal plate in a manner that prevents it from
becoming magnetized.

If anything is found, replace drive plate.

OIL JET

Check nozzle for deformation and damage.

Blow compressed air from nozzle, and check for clogs.

If it is not satisfied, clean or replace oil jet.

OIL JET RELIEF VALVE

Using clean plastic stick, press check valve in oil jet relief valve.
Make sure that valve moves smoothly with proper reaction
force.

If it is not satisfied, replace oil jet relief valve.
