0.01 mm (0.0004 in.) or less

MAIN BEARINGS AND CONNECTING ROD BEARINGS
OIL CLEARANCE MEASUREMENT

1.3 L

Standard value

Journal oil clearance No. 1, 2, 4, 5 :

0.028 ~ 0.046 mm (0.0011 ~ 0.0018 in.)

Journal oil clearance No. 3 (center) :

0.034 ~ 0.52 mm (0.0013 ~ 0.002 in.)

Pin oil clearance :

0.024 ~ 0.042 mm (0.0009 ~ 0.0017 in.)

1.1 L

Standard value

Journal oil clearance No. 1, 2, 3, 4, 5 :

0.020 ~ 0.038 mm (0.0007 ~ 0.0014 in.)

Pin oil. clearance :

0.012 ~ 0.041 mm (0.0005 ~ 0.0016 in.)

PLASTIC GAUGE METHOD
1.

Remove oil, greass and any other dirt from bearings and journals.

2.

Cut plastic gauge to the same length as the width of the bearing and place ot parallel with the journal, off from the oil holes.

3.

Install the crankshaft , bearings, and caps. Tighten them to the specified torques. During this operation, do not turn the crankshaft. Remove the caps.

Measure the width of the plastic gauge at the widest point using the scale printed on the gauge package.

If the clearance exceeds the repair limit, replace the bearing.

Should the standard clearance not be obtained even after bearing replacement, the journal should be fround to a recommended undersize, and a bearing of the same size should be installed.

OIL SEAL
CRANKSHAFT POSITION SENSOR WHEEL
1.

Remove the crankshaft position sensor wheel.

2.

Check the crankshaft position sensor wheel for damage, cracks and wear, and replace if necessary.

3.

Check the clearance between the crankshaft position sensor wheel and the crankshaft position sensor with a depth gage.

Standard value

Clearance between the crankshaft position sensor wheel and crankshaft position sensor :

0.5 ~ 1.5 mm (0.0020 ~ 0.059 in.)

note
1.

Measure the depth of the top of the crankshaft position sensor wheel teeth and the outside of transaxle housing.

2.

Measure the difference between the crankshaft position sensor length and depth.

3.

The crankshaft position sensor length is the distance between the end of crankshaft position sensor and inner point of contacting face.

REASSEMBLY

Install the flywheel assembly and tighten the bolts to the specified forque.

Tightening torque

Flywheel bolt

1.3L : 130~140Nm (1300~1400 kg.cm, 96~103 lb.ft)

1.1L : 80~80Nm (700~800 kg.cm, 52~59 lb.ft)

REASSEMBLY
1.

Install the upper main bearing inserts in the cylinder block.

2.

Install the crankshaft. Apply engine oil to the journals.

3.

Install bearing caps and tighten cap bolts to the specified torque in the sequence of the center, No.2, 4, front and rear caps.

Cap bolts should should be tightened evenly in 2 to 3 stages before they are tightened to the specified torque.

The caps should be installed with the arrow mark directed toward the crank pulley side of engine. Cap numbers must be correct.

Tightening torque

Main bearing cap bolt

1.3 L : 55 ~ 60 Nm (550 ~ 600 kg.cm, 41 ~ 44 lb.ft)

1.1 L : 50 ~ 55 Nm ( 500 ~ 550 kg.cm, 37 ~ 41 lb.ft)

Connecting rod cap bolt

1.3 L : 32 ~ 35 Nm (320 ~ 350 kg.cm, 24 ~ 26 lb.ft)

1.1 L : 20 ~ 23 Nm (200 ~ 230 kg.cm, 15 ~ 17 lb.ft)

4.

Make certain that the crankshaft turns freely and has the proper clearance between the center main bearing thrust flange and the connecting rod big end bearing.

Standard value

Crankshaft end play

1.3 L : 0.05 ~ 0.175 mm (0.002 ~ 0.005 in.)

1.1 L : 0.05 ~ 0.25 mm (0.002 ~ 0.010 in.)

5.

Install the oil seal in the crankshaft rear oil seal case.

Use the Special Tool, Crankshaft Rear Oil Seal installer (09231 - 21000) as shown. Press and fit the oil seal in all the way, being careful not to misalign it.

6.

Install the rear oil seal case and gasket. Tighten the five bolts.

Apply engine oil to the oil seal lips and crankshaft of the time of installation.

7.

Install the rear plate and tighten the bolts.

8.

Install the connecting rod caps. Refer to the "Piston and Connecting Rods" section.
