Crankshaft - Assembly

1. Install the upper main bearing inserts into the crankshaft bearing bores in the cylinder block.

Be careful when installing the main bearing inserts removed during disassembly. Position them according to the alignment marks made before removal.

2. Install the crankshaft. Apply engine oil to the crankshaft main journals.

3. Install the lower bearing inserts and main bearing caps. Tighten the main bearing cap bolts to the specified torque in the following sequence: center bearing cap, No. 2 bearing cap, No. 4 bearing cap, front bearing cap and rear bearing cap.

Tighten the bolts gradually in two or three steps, then tighten to the specified torque.

When installing the caps, position them so that the arrows on the caps point toward the crankshaft pulley and the cap numbers match the cylinder numbers.

Tightening torque, main bearing cap bolts:

55 - 60 N·m Connecting rod cap bolts:

32 - 35 N·m

4. Check again that the crankshaft rotates smoothly and that the crankshaft end play (clearance between the thrust flange of the center main bearing and the corresponding crankshaft web) is within the specified value.

Standard value:

Crankshaft end play: 0.050 - 0.175 mm

5. Using the special service tool (rear crankshaft oil seal installer 092312100), install the rear crankshaft oil seal into the seal housing as shown in the illustration. Be careful to position the installer correctly so as not to damage or deform the seal during installation.

6. Install the cylinder block rear plate and tighten its mounting bolts.

7. Install the connecting rod caps.

8. Install the flywheel, oil pump housing, oil pan, and timing belt. Refer to the relevant sections for installation procedures.
