- Ensure the oil holes on cylinder block and those on the corresponding bearing are aligned.
- Install crankshaft to cylinder block.
- While turning crankshaft by hand, check that it turns smoothly.
- Install main bearing caps.
- Main bearing caps are identified by identification mark cast on them. For installation, face front mark (E) to front side.
NOTE: Main bearing cap cannot be replaced as a single part, because it is machined together with cylinder block.
- Main bearing caps are identified by identification mark cast on them. For installation, face front mark (E) to front side.
- Install main bearing beam.
- Install main bearing beam with front mark facing downward (oil pan side).
- Install main bearing beam with front mark facing front of the engine.
- Install main bearing cap bolts in numerical order as shown in the illustration as follows:

- Inspect the outer diameter of main bearing cap bolt. Refer to "INSPECTION ".
- Apply new engine oil to threads and seat surfaces of main bearing cap bolts.
- Tighten main bearing cap bolts in several different steps.
Torque Specifications: 35.3 N.m (3.6 kg-m, 26 ft-lb)
- Turn all main bearing cap bolts 90 degrees clockwise (angle tightening).CAUTION: Use the angle wrench [SST: KV10112100 (BT8653-A)] to check tightening angle. Never make judgment by visual inspection.
- After installing main bearing cap bolts, check that crankshaft can be rotated smoothly by hand.
- Check the crankshaft end play. Refer to "INSPECTION ".
- Install piston to connecting rod as follows:
- Using snap ring pliers, install new snap ring to the groove of piston rear side.
- Insert it fully into groove to install.
- Install piston to connecting rod.
- Using an industrial drier or similar tool, heat piston until piston pin can be pushed in by hand without excess force [approximately 60 to 70°C (140 to 158°F)]. From the front to the rear, insert piston pin into piston and connecting rod.
- Assemble so that the front mark on the piston crown and the cylinder number on connecting rod are positioned as shown in the illustration.
- Install new snap ring to the groove of the piston front side.
- Insert it fully into groove to install.
- After installing, check that connecting rod moves smoothly.
- Using snap ring pliers, install new snap ring to the groove of piston rear side.
- Using a piston ring expander (commercial service tool) (A), install piston rings.CAUTION:
- When installing piston rings, be careful not to damage piston.
- Never damage piston rings by expending them excessively.
- If there is stamped mark on ring, mount it with marked side up.NOTE: If there is no stamp on ring, no specific orientation is required for installation.
Stamped mark:
Top ring (A) : -
Second ring (B) : 2 R
- Position each ring with the gap as shown in the illustration referring to the piston front mark (D).
- Check the piston rings side clearance. Refer to "INSPECTION ".
- Install connecting rod bearings to connecting rod and connecting rod bearing cap.CAUTION: Never drop connecting rod bearing, and to scratch the surface.
- Before installing connecting rod bearings, apply engine oil to the bearing surface (inside). Do not apply engine oil to the back surface, but thoroughly clean it.
- When installing, align connecting rod bearing stopper protrusion (B) with cutout (C) of connecting rod and connecting rod bearing cap to install.
- Ensure the oil hole (A) on connecting rod and that on the corresponding bearing are aligned.
- Install piston and connecting rod assembly to crankshaft.
- Position crankshaft pin corresponding to connecting rod to be installed onto the bottom dead center.
- Apply engine oil sufficiently to the cylinder bore, piston and crankshaft pin journal.
- Match the cylinder position with the cylinder number on connecting rod to install.
- Be sure that front mark on piston crown is facing front of engine.
- Using a piston ring compressor [SST: EM03470000 (J-8037)] (A) or suitable tool, install piston with the front mark on the piston crown facing the front of the engine.CAUTION: Never damage the cylinder wall and crankshaft pin, resulting from an interference of the connecting rod big end.
- Install connecting rod bearing cap.
- Match the stamped cylinder number marks on connecting rod with those on connecting rod bearing cap to install.
- Be sure that front mark (H) on connecting rod bearing cap is facing front of the engine.
- Tighten connecting rod bolt as follows:
- Inspect the outer diameter of connecting rod bolt. Refer to "INSPECTION ".
- Apply engine oil to the threads and seats of connecting rod bolts.
- Tighten connecting rod bolts.
Torque Specifications: 19.6 N.m (2.0 kg-m, 14 ft-lb)
- Then tighten all connecting rod bolts 90 degrees clockwise (angle tightening).CAUTION: Always use the angle wrench [SST: KV10112100 (BT8653-A)]. Avoid tightening based on visual check alone.
- After tightening connecting rod bolts, check that crankshaft rotates smoothly.
- Check the connecting rod side clearance. Refer to "INSPECTION ".
- Install baffle plate to main bearing beam.
- Install new rear oil seal retainer to cylinder block. Refer to "REAR OIL SEAL : REMOVAL AND INSTALLATION ".
- Install pilot converter.
- With drift [outer diameter: approximately 33 mm (1.30 in)], press-fit as far as it will go.
- Press-fit pilot converter with its chamfer facing crankshaft as shown in the illustration.
- Install knock sensors.
- Install knock sensor so that connector faces the rear of the engine.
- After installing knock sensor, connect harness connector, and lay it out to rear of engine.CAUTION:
- Never tighten mounting bolts while holding connector.
- If any impact by dropping is applied to knock sensor, replace it with new one.
NOTE:- Check that there is no foreign material on the cylinder block mating surface and the back surface of knock sensor.
- Check that knock sensor does not interfere with other parts.
- Note the following, assemble in the reverse order of disassembly after this step.
Drive plate
- When installing drive plate to crankshaft, be sure to correctly align crankshaft side dowel pin and drive plate side dowel pin hole.
- If these are not aligned correctly, engine runs roughly and "MIL" turns on.
- Install drive plate (2) and reinforcement plate (3) as shown in the illustration.
- Holding ring gear with the pulley holder (commercial service tool).
- Tighten mounting bolts crosswise over several times.
- When installing drive plate to crankshaft, be sure to correctly align crankshaft side dowel pin and drive plate side dowel pin hole.
