CRANKSHAFT INSPECTION

1. Install the main bearing cap. (See Main Bearing Cap Assembly Note.)

2. Measure the crankshaft end play.

• If it exceeds the specification, replace the thrust bearing or crankshaft so that the specified end play is obtained.

0.22-0.45 mm {0.0087-0.0177 in}

0.55 mm {0.022 in}

3. Remove the main bearing cap. (See Camshaft Cap Disassembly Note.)

4. Measure the crankshaft runout.

• If it exceeds the specification, replace the crankshaft.

L3, L3 (with variable valve timing mechanism)

0.05 mm {0.0019 in}

5. Measure the journal diameter in X and Y directions at the two points (A and B) as indicated in the figure.

• If it exceeds the specification, replace the crankshaft or grind the journal and install the undersize bearing.

Maximum out-of-round

0.05 mm {0.0019 in}

6. Install the main bearing caps and crankshaft.

7. Position a plastigauge atop the journals in the axial direction.

8. Install the main bearing caps and cylinder block. (See Main Bearing Cap Assembly Note.)

9. Remove the main bearing caps. (See Camshaft Cap Disassembly Note.)

10. Measure the main journal oil clearance.

• If it exceeds the specification, replace the main bearing using the main bearing selection table or grind the main journal and install the oversize bearings so that the specified oil clearance is obtained.
