• Remove connecting rod cap and bearing, 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 OIL CLEARANCE
Method by Calculation • Install main bearings to cylinder block and main bearing cap, and tighten main bearing cap bolts to the spec- ified torque. Refer to EM-96, " Disassembly and Assembly " .
• Measure the inner diameter of main bearing with a bore gauge.
(Bearing oil clearance) = (Main bearing inner diameter) – (Crank-
shaft main journal diameter)
• If the clearance exceeds the limit, select proper main bearing according to main bearing inner diameter and crankshaft main
journal diameter to obtain the specified bearing oil clearance.
Refer to EM-113, " Main Bearing " .
Method of Using Plastigage • Remove engine oil and dust on crankshaft main 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.
• Install main bearings to cylinder block and main bearing cap, and tighten main bearing cap bolts to the spec- ified torque. Refer to EM-96, " Disassembly and Assembly " .
CAUTION:
Never rotate crankshaft.
• Remove main 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”.
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 bearing
must protrude. Refer to EM-96, " Disassembly and Assembly " .
• If the standard is not met, replace main bearings. Main Bearing " .

• Removal and installation of the door glass.
• Removal and installation of the door glass run.
Initialization After installing each component to the vehicle, follow the steps below.
1. Disconnect the battery negative c able 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 procedure if the
window is already fully opened).
4. Move the power window switch in the up direction (auto close position) and hold. Keep holding the switch
even when window is completely closed, and then release after 4 seconds have passed.
5. Inspection of the ant i-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.
2. Place a wooden piece (wooden hammer handle, etc.) near the fully closed position.
3. Carry out fully closing operation with auto up switch.
• Check that the glass reverses without pinching the w ooden piece, is lowered approx.150 mm (5.91 in) or for
2 seconds and then stops.
• The glass should not be raised with power window main switch while it is reversing or lowering.
CAUTION:
• Use care to avoid being pinched du ring the inspection. Do not use a hand, etc. in place of the
wooden piece durin g the inspection.
• Check that auto up function is normal before inspection, following the system initialization.
FITTING INSPECTION • Make sure the glass is securely fit into the glass run groove.
• Lower the glass slightly [approx. 10 to 20 mm (0.39 to 0.79 in)] and make sure the clearance to the sash is parallel. If the clearance between the glass and sash is not parallel, loosen the regulator bolts, guide rail
bolts, and the glass and guide rail bolts to correct the glass position.
• Make sure the system is normal with raising and lowering the glass.
