Disassembly
note

Use fender covers to avoid damaging painted surfaces.

To avoid damaging the cylinder head, wait until the engine coolant temperature drops below normal temperature (20°C [68°F]) before removing it.

When handling a metal gasket, take care not to fold the gasket or damage the contact surface of the gasket.

To avoid damage, unplug the wiring connectors carefully while holding the connector portion.

Keep the main bearing caps with their bearings assembled together.

Inspection
1.

Check the crankshaft main bearing oil clearance.

(1)

To check main bearing-to-journal oil clearance, remove the bearing caps with their lower bearings.

(2)

Clean each main journal and lower bearing with a clean shop towel.

(3)

Place one strip of plastigage across each main journal.

(4)

Reinstall the bearing caps with their lower bearings, then tighten the bolts.

Tightening torque :

49.0 N.m (5.0 kgf.m, 36.2 lb-ft) + 120°

note

Do not turn the crankshaft.

Do not reuse the main bearing cap bolts.

(5)

Remove the bearing caps with their lower bearing again, and measure the widest part of the plastigage.

Bearing oil clearance :

0.026 ~ 0.044 mm (0.0010 ~ 0.0017 in)

(6)

If the plastigage measures too wide or too narrow, remove the upper and lower bearing and then install a new bearings with the same color mark. Recheck the oil clearance.

note

Do not file, shim, or scrape the bearings or the cap to adjust clearance.

(7)

If the plastigage shows the clearance is still incorrect, try the next larger or smaller bearing. Recheck the oil clearance.

note

If the proper clearance cannot be obtained by using the appropriate larger or smaller bearings, replace the crankshaft and start over.

note

If the marks are indecipherable because of an accumulation of dirt and dust, do not scrub them with a wire brush or scraper. Clean them only with solvent or detergent.

(8)

Select the bearing by using selection table.

Letters have been stamped on the side of block as a mark for the size of each of the 5 main journal bores.

Use them, and the numbers or letters stamped on the crank (marks for main journal size), to choose the correct bearings.

Reassembly
note

Thoroughly clean all parts to assembled.

Before installing the parts, apply fresh engine oil to all sliding and rotating surfaces.

caution

Upper bearings have an oil groove of oil holes ; Lower bearings do not.

(1)

Align the bearing claw with the claw groove of the cylinder block, and push in the 5 upper bearings (A).

(2)

Align the bearing claw with the claw groove of the main bearing cap (B), and push in the 5 lower bearings (A).

(3)

Apply a coat of engine oil after assembling the main bearings.

2.

Install the thrust bearings (No.4 journal).

Install the 2 thrust bearings (B) on both sides of the No.4 journal of the cylinder block with the oil groove (A) facing out.

3.

Place the crankshaft (A) on the cylinder block.

Apply a coat of engine oil to the pin and main journals after assembling the crankshaft.

4.

Install the main bearing caps (B) and tighten the cap bolts.

note

Do not reuse the bearing cap bolts.

Be sure to assemble the main bearing caps in correct order.

Install the main bearing cap with the arrow facing the front of the engine.

Tighten all the main bearing cap bolts with the specified torque first, and then retighten all the bolts with the specified angle.

(1)

Apply a light coat of engine oil on the threads of the bolts. Tighten all the bolts with the specified torque in numerical order first, then tighten all the bolts with the specified angle in numerical order.

Tightening torque :

49.0 N.m (5.0 kgf.m, 36.2 lb-ft) + 120°

Using the SST (09221-4A000) (C), tighten the main bearing cap bolts.

(2)

Check that the crankshaft turns smoothly.

5.

Check the crankshaft end play.

6.

Assemble the other parts in the reverse order of disassembly.

caution

In case the crankshaft is replaced with a new one, select the proper connecting rod bearing according to the pin journal mark on the crankshaft.
