Crankshaft

Inspection

• Clean the crankshaft oil passages with pipe cleaners

or a suitable brush.

• Check the keyway and threads.

Alignment

• Measure runout on all main journals to make sure the

crankshaft is not bent.

• The difference between measurements on each journal

must not be more than the service limit.

Crankshaft Total Runout:

Standard (New): 0.020 mm (0.0008 in) max.

Service Limit: 0.030 mm (0.0012 in)

DIAL INDICATOR

Rotate two complete

revolutions.

Support with lathe-

type tool or V-blocks.
Out-of-Round and Taper

• Measure out-of-round at the middle of each rod and

main journal in two places.

• The difference between measurements on each journal

must not be more than the service limit.

Journal Out-of-Round:

Standard (New): 0.004 mm (0.0002 in) max.

Service Limit: 0.010 mm (0.0004 in)

Measure taper

at edges.

Measure out-of-

round at middle.

• Measure taper at the edges of each rod and main

journal.

• The difference between measurements on each journal

must not be more than the service limit.

Journal Taper:

Standard (New): 0.005 mm (0.0002 in) max.

Service Limit: 0.010 mm (0.0004 in)ProCarManuals.com

3. Stop after the ring compressor pops free, and check

the connecting rod-to-crank journal alignment

before pushing the piston into place.

4. Install the rod caps with bearings, and torque the

nuts to 44 N-m (4.5 kgf-m, 33 Ibf-ft).
RUBBER HOSES
CORRECT
Pistons

Installation

Before installing the piston, apply a coat of engine

oil to the ring grooves and cylinder bores.

1. Install the ring compressor, check that the bearing

is securely in place; then position the piston in the

cylinder and tap it in using the wooden handle of a

hammer.

2. Install the piston/connecting rod assemblies in the

cylinder block.

• Guide the piston carefully to prevent damage.

• Fit long rubber hoses (about 30 cm (12 in) long)

to the connecting rod bolts to protect the crank-

shaft.

• Install the pistons after setting the crankshaft to

BDC for each cylinder.

INCORRECT
The arrow must face

the timing belt side

of the engine and the

connecting rod oil hole

must face the right side

of the engine.

10. Apply liquid gasket to the cylinder block mating sur-

face of the rear cover, then install the cover on the

cylinder block.

Apply liquid gasket

along the broken line.

Do not apply liquid gasket

to O-ring groove.

NOTE:

• Use liquid gasket, Part No. 08718 - 0001 or 08718

- 0003.

• Check that the mating surfaces are clean and dry

before applying liquid gasket.

• Apply liquid gasket evenly, being careful to cover

all the mating surface.

• To prevent oil leakage, apply liquid gasket to the

inner threads of the bolt holes.

• Do not apply liquid gasket to O-ring grooves.

• Do not install the parts if five minutes or more

have elapsed since applying liquid gasket.

Instead reapply liquid gasket after removing old

residue.

• After assembly, wait at least 30 minutes before

filling the engine with oil.

Apply liquid gasket

O-RING GROOVE
NOTE:

• Apply a light coat of oil to the crankshaft and to the

lip of the oil seal.

• Use a new O-ring and apply oil when installing it.

The numbers in the middle of the API Service label tell

you the oil's SAE viscosity or weight. Select the oil for

your vehicle according to this chart:

Ambient Temperature

An oil with a viscosity of 5W - 30 is preferred for

improved fuel economy and year-round protection in

the vehicle. You may use a 10W - 30 oil if the climate in

your area is limited to the temperature range shown on

the chart.

Cap Testing
Testing

1. Remove the radiator cap, wet its seal with engine

coolant, then install it on the pressure tester.

RADIATOR

CAP

2. Apply a pressure of 93- 123 kPa (0.95- 1.25 kgf/cm2,

14-18 psi).

3. Check for a drop in pressure.

4. If the pressure drops, replace the cap.
1. Wait until the engine is cool, then carefully remove

the radiator cap and fill the radiator with engine

coolant to the top of the filler neck.

2. Attach the pressure tester to the radiator and apply

a pressure of 93-123 kPa (0.95 - 1.25 kgf/cm2, 14 -

18
psi).
