CRANKSHAFT RUNOUT

●

Place a V-block on a precise flat table to support the journals on
the both end of the crankshaft.

●

Place a dial gauge straight up on the No. 3 journal.

●

While rotating the crankshaft, read the movement of the pointer
on the dial gauge. (Total indicator reading)

●

If it exceeds the limit, replace the crankshaft.

OIL CLEARANCE OF CONNECTING ROD BEARING
Method by Calculation

●

Install the connecting rod bearings to the connecting rod and the
cap, and tighten the connecting rod bolts to the specified torque.
Using a inside micrometer measure the inner diameter of con-
necting rod bearing. Refer to

EM-104, "ASSEMBLY"

for the

tightening procedure.
(Oil clearance) = (Inner diameter of connecting rod bearing) –
(Outer diameter of crankshaft pin)

●

If clearance cannot be adjusted within the standard, grind crank-
shaft pin and use undersized bearing. Refer to

EM-111, "HOW TO SELECT CONNECTING ROD BEAR-

ING"

Method of Using Plastigage

●

Remove oil and dust on the crankshaft pin and the surfaces of
each bearing completely.

●

Cut a plastigage slightly shorter than the bearing width, and
place it in crankshaft axial direction, avoiding oil holes.

●

Install the connecting rod bearings to the connecting rod and
the cap, and tighten the connecting rod bolts to the specified
torque. Refer to

EM-104, "ASSEMBLY"

for the tightening proce-

dure.

CAUTION:

Never rotate the crankshaft.

●

Remove the connecting rod 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”.

OIL CLEARANCE OF MAIN BEARING
Method by Calculation

●

Install the main bearings to the cylinder block and bearing cap.
Measure the main bearing inner diameter with the bearing cap
bolt tightened with main bearing beam to the specified torque.
Refer to

EM-104, "ASSEMBLY"

for the tightening procedure.

(Oil clearance) = (Inner diameter of main bearing) – (Outer
diameter of crankshaft journal)

●

If the measured value exceeds the limit, select main bearings
referring to the main bearing inner diameter and crankshaft jour-
nal outer diameter, so that the oil clearance satisfies the standard. Refer to

EM-112, "HOW TO SELECT

MAIN BEARING"

Method of Using Plastigage

●

Remove oil and dust on the crankshaft journal and the surfaces
of each bearing completely.

●

Cut a plastigage slightly shorter than the bearing width, and
place it in crankshaft axial direction, avoiding oil holes.

●

Tighten the main bearing bolts with main bearing beam to the
specified torque. Refer to

EM-104, "ASSEMBLY"

for the tighten-

ing procedure.

CAUTION:

Never 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 main bearing cap is removed after being tightened to
the specified torque with main bearings installed, the tip end of
bearing must protrude. Refer to

EM-104, "ASSEMBLY"

for the

tightening procedure.

●

If the standard is not met, replace main bearings.

CRUSH HEIGHT OF CONNECTING ROD BEARING

●

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

EM-104,

"ASSEMBLY"

for the tightening procedure.

●

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

OUTER DIAMETER OF MAIN BEARING CAP BOLT

●

Measure outer diameters (d1, d2) at two positions shown in the
figure.

●

Measure d2 at a point within block A.

●

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 shown in the figure.

●

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

SIGNAL PLATE

●

Check the drive plate and signal plate for deformation or cracks.

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 a clean plastic stick, press check valve in oil jet relief
valve. Make sure that valve moves smoothly with proper reac-
tion force.

●

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