Inspect the crankshaft journal for taper and out-of-round.
Standard value |
Crankshaft journal O.D : |
60.002 - 60.020 mm (2.362 - 2.363 in.) |
Crankshaft pin O.D : |
50.008 - 50.026 mm(1.969 - 1.9695 in.) |
Remove the timing belt, front case, flywheel, cylinder head assembly and oil pan. For details, refer to the respective chapters.
Remove the rear plate and the rear oil seal.
Remove the connecting rod caps.
Mark the main bearing caps to be able to reassembl in the original position and direction.
Remove the bedplate and the crankshaft. Keep the bearings in order according to the cap number.

Crankshaft journal O.D : |
60.002 - 60.020 mm (2.362 - 2.363 in.) |
Crankshaft pin O.D : |
50.008 - 50.026 mm(1.969 - 1.9695 in.) |
Standard value |
Oil clearance |
Crankshaft main bearing : |
0.024 - 0.042 mm (0.0009 - 0.0017 in.) |
Connecting rod bearing : |
0.024 - 0.042 mm (0.0009 - 0.0017 in.) |
Limit : 0.1 mm (0.0039 in.) |
Remove oil, grease and any other dirt from the bearings and journals.
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.
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 thecorresponding size should be installed.
: 0.09 - 0.32 mm (0.0035 - 0.026 in.) |
Check the clutch disc contacting surface of the flywheel for damage and wear. Replace the flywheel if excessively damaged or worn.
Check the clutch disc contacting surface of the flywheel for run-out.
Limit |
Flywheel run - out : 0.13 mm (0.0051 in.) |
Check the ring gear for damage, cracks and wear. Replace if necessary.
Install a grooved main bearing (upper bearing) on the cylinder block side.
Install a grooveless main bearing (lower bearing) on the main bearing cap side.
Lower center thrust bearing is grooveless. Upper center thrust bearing is grooveed.
Apply engine oil to journals and pins. Install the crankshaft.
Install the bedplate . (Apply loctite 5205)
Tighten the cap bolts to the specified torque.
Tightening torque |
Main bearing cap bolts : |
15 mm : |
28 - 32 Nm (280 - 320 kg.cm, 20.7 - 23.6 lb.ft) + 120° |
12 mm : |
33.7 - 37.7 Nm (337 - 377 kg.cm, 24.9 - 27.8 lb.ft) |
Cap bolts should be tightened evenly in 4 to 5 increments before they are tightened to the specified torque.
Make sure that the crankshaft turns freely and check the end play of the crankshaft.
Using a special tool (09231 - 27000). Install the oil seal in the oil seal case. A new oil seal should be used.
Install the flywheel assembly and tighten the bolts to the specified torque.
Tightening torque |
Flywheel bolt : |
70 - 80 Nm (700 - 800kg.cm, 52 - 59 lb.ft) |
Install the drive plate and tighten the bolts to the specified torque.
Tightening torque |
Drive plate : 70 - 80 Nm (700 - 800kg.cm, 52 - 59 lb.ft) |
