Remove main bearing caps 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”.
MAIN BEARING CRUSH HEIGHT
When main bearing cap is removed after being tightened to the
specified torque with main bearings installed, the tip end of bear-
ing must protrude. Refer to EM-128, "
ASSEMBLY" for the tight-
ening procedure.
If the standard is not met, replace main bearings.
CONNECTING ROD BEARING CRUSH HEIGHT
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-128,
"ASSEMBLY" for the tightening procedure.
If the standard is not met, replace connecting rod bearings.
MAIN BEARING CAP BOLT OUTER DIAMETER
Measure the outer diameters (“d1 ”, “d2 ”) at two positions as
shown in the figure.
If reduction appears in “A” range, regard it as “d2 ”.
If it exceeds the limit (large difference in dimensions), replace
main bearing cap bolt with new one.

CONNECTING ROD BEARING OIL CLEARANCE
Method by Calculation
Install connecting rod bearings to connecting rod and cap, and
tighten connecting rod bolts to the specified torque. Refer to
EM-254, "
ASSEMBLY" for the tightening procedure.
Measure the inner diameter of connecting rod bearing with
inside micrometer.
(Bearing oil clearance) = (Connecting rod bearing inner diameter) –
(Crankshaft pin journal diameter)
If the calculated value exceeds the limit, select proper connecting rod bearing according to connecting rod
big end diameter and crankshaft pin journal diameter to obtain the specified bearing oil clearance. Refer
to EM-261, "
HOW TO SELECT CONNECTING ROD BEARING" .
Method of Using Plastigage
Remove oil and dust on crankshaft pin journal and the surfaces of each bearing completely.
Cut plastigage slightly shorter than the bearing width, and place it in crankshaft axial direction, avoiding oil
holes.
Install connecting rod bearings to connecting rod and cap, and tighten connecting rod bolts to the speci-
fied torque. Refer to EM-254, "
ASSEMBLY" for the tightening procedure.
CAUTION:
Do not rotate crankshaft.
Remove connecting rod bearing cap and bearing, 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”.Standard : 0.020 - 0.045 mm (0.0008 - 0.0018 in)

Initialization
After installing each component to the vehicle, follow the steps below.
1. Disconnect the minus terminal of battery or disconnect power window switch's harness connector tempo-
rarily, then reconnect after at least 1 minute.
2. Turn ignition switch ON.
3. Open the window to its full width by operating the power window switch. (Exclude this pocedure if the win-
dow is already fully opened)
4. Fully draw the power window switch in up direction (auto close position) and hold, keep holding the switch
even when window is completely closed and then release afeter 3 second has passed.
5. Inspection of the anti-pinch system function.
NOTE:
Initialization may be cancelled with continuous opening and closing operation.In this case, initialize the
system.
INSPECT THE FUNCTION OF THE ANTI-PINCH SYSTEM.
1. Fully open the door glass.
