DISASSEMBLY
1.

Remove the timing belt, front case, flywheel, cylinder head assembly and oil pan. For details, refer to the respective chapters.

2.

Remove the rear plate and the rear oil seal.

3.

Remove the connecting rod caps.

note

Mark the main bearing caps to be able to reassembl in the original position and direction.

4.

Remove the main bearing caps and the crankshaft. Keep the bearings in order according to the cap number.

INSPECTION
Crankshaft
1.

Check the crankshaft journals and pins for damage, uneven wear and cracks. Also check the oil holes for restrictions. Repair or replace any defectivepart.

2.

Inspect the crankshaft journal for taper and out-of-round.

Standard value

Crankshaft journal O.D :

56.982 - 57.000 mm (2.2434 - 2.2441 in.)

Crankshaft pin O.D :

44.980 - 45.000 mm (1.7709 - 1.7717 in.)

MAIN BEARINGS AND CONNECTING ROD BEARINGS
MEASURING OIL CLEARANCE

Standard value

Oil clearance

Crankshaft main bearing

No.1,2,4,5 : 0.018 - 0.036 mm (0.0007 - 0.0014 in.)

No.3 : 0.024 - 0.042 mm (0.0009 - 0.0017 in.)

Connecting rod bearing :

0.015 - 0.048 mm (0.0006 - 0.0019 in.)

Limit : 0.1 mm (0.0039 in.)

HOW TO USE PLASTIC GAUGE
1.

Remove oil, grease and any other dirt from the bearings and journals.

2.

Cut the plasticgauge to the same length as the width of the bearing and place it in parallel with the journal, avoiding the oil holes.

3.

Install the crankshaft, bearings and caps and tighten them to the specified torques. During this operation, do not turn the crankshaft. Remove the caps. Measure the width of the plasticgauge at the widest part by using the scale printed on the gauge package. If the clearance exceeds the service limit, the bearing should be replaced or an undersize bearing should be used. When installing a new crankshaft, be sure to use standard size bearings. If the standard clearance can not be obtained even after replacing the bearing, the journal and pin should be ground to thr undersize and a bearing of the correspondingsize should be installed.

OIL SEAL
BEARING CAPS

Standard value : 0.05 - 0.25 mm (0.0020 - 0.0098 in.)

DRIVE PLATE (A/T)
FLYWHEEL (M/T)
1.

Check the clutch disc contacting surface of the flywheel for damage and wear. Replace the flywheel if excessively damaged or worn.

2.

Check the clutch disc contacting surface of the flywheel for run-out.

Limit

Flywheel run - out : 0.13 mm(0.0051 in.)

3.

Check the ring gear for damage, cracks and wear. Replace if necessary.

REASSEMBLY
1.

Install a grooved main bearing (upper bearing) on the cylinder block side.

2.

Install a grooveless main bearing (lower bearing) on the main bearing cap side.

3.

Both upper and lower center thrust bearings are grooveless.

4.

Apply engine oil to journals and pins. Install the crankshaft.

5.

Install the bearing caps with the arrow mark directed toward the front of the engine. The cap number must be correct.

6.

Tighten the cap bolts to the specified torque.

Tightening torque

Main bearing cap bolts : 25 Nm (250, 18lb.ft) + (90°)

7.

Cap bolts should be tightened evenly in 4 to 5 increments before they are tightened to the specified torque.

8.

Make sure that the crankshaft turns freely and check the end play of the crankshaft.

9.

Using a special tool (09231 - 21000). Install the oil seal in the oil seal case. A new oil seal should be used.

10.

Install the oil seal into the oil seal case so that the oil hole in the separator may be directed downward (arrow in illustration)

11.

Install the new oil seal case gasket and oil seal case assembly.

Tightening torque

Oil seal case : 10 - 12 Nm (100 - 120 kg.cm, 7 - 9 lb.ft)

12.

Install the rear plate to the cylinder block.

13.

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

Tightening torque

Flywheel bolt :

130 - 140 Nm (1300 - 1400 kg.cm, 94 - 101l b.ft)

14.

Install the adapter plate to the cylinder block.

15.

Install the drive plate and tighten the bolts to the specified torque.

Tightening torque

Drive plate :

130 - 140 Nm (1300 - 1400 kg.cm,94 - 101 lb.ft)
