Starter Solenoid Test

1. Remove the starter solenoid from the gear housing.

2. Check for continuity between the terminals in each

solenoid plunger position according to the table.

Starter Field Winding Test

1. Check for continuity between the brushes. If there's

no continuity, replace the armature housing.

2. Check for continuity between each brush and the

armature housing (ground).

If continuity exists, replace the armature housing.

4.

Check for mica depth. If necessary, undercut the mica

with a hacksaw blade to achieve proper depth. If the

service limit cannot be maintained, replace the arma-

ture.

5.
Check for continuity between the segments of the

commutator. If an open circuit exists between any

segments, replace the armature.

6.
Place the armature on an armature tester. Hold a

hacksaw blade on the armature core. If the blade is

attracted to the core or vibrates while the core is

turned, the armature is shorted. Replace the arma-

ture.

7. With an ohmmeter, check that no continuity exists

between the commutator and armature coil core,

and between the commutator and armature shaft. If

there is continuity, replace the armature.

Rotor Slip Ring Test

1. Check the resistance between the slip rings.

There should be 2.9 ohms.

If resistance meets the specification, go to step 2.

If resistance does not meet the specification,

replace the alternator.

2. Check that there is no continuity between the slip

rings and the rotor or rotor shaft.

3. If the rotor fails either continuity check, replace the

alternator.
Stator Test

1. Check that there is continuity between each pair of

leads.

COIL CORE

2. Check that there is no continuity between each lead

and the coil core.

3. If the coil fails either continuity check, replace the

4. Remove the bolts, then remove the camshaft hold-

ers from the cylinder head.

5. Lift the camshaft out of the cylinder head, wipe it

clean, then inspect the lift ramps. Replace the

camshaft if any lobes are pitted, scored, or excessively

worn.

6. Clean the camshaft bearing surfaces in the cylinder

head, then set the camshaft back in place.

7. Place a plastigage strip across each journal.

8. Install the camshaft holders, then tighten the bolts

to the specified torque shown on the previous page.

9. Remove the camshaft holders. Measure the widest

portion of plastigage on each journal.

PLASTIGAGE STRIP
If camshaft-to-holder oil clearance is out of toler-

ance:

And the camshaft has already been replaced,

you must replace the cylinder head.

If the camshaft has not been replaced, first check

the total runout with the camshaft supported on

V-blocks.

Rotate camshaft

while measuring.

If the total runout of the camshaft is within toler-

ance, replace the cylinder head.

If the total runout is out of tolerance, replace the

camshaft and recheck. If the oil clearance is still

out of tolerance, replace the cylinder head.

11. Check cam lobe height wear.

Check this area for wear.

Hydraulic Tappets

Bleeding

1. Fill a container with 5W - 30 or 10W - 30 engine oil,

and place the hydraulic tappet in it. Press down on

the check ball with a thin wire. Bleed the tappet of

air by pumping the plunger slowly until no bubbles

come out of the hydraulic tappet.

Cylinder Heads

Installation (cont'd)

4. Install the cylinder heads on the cylinder block.

5. Tighten the cylinder head bolts sequentially in 2 or

3 steps.

Specified Torque:

76 N-m (7.8 kgf-m, 56 Ibf-ft)

NOTE:

We recommend using a beam-type torque wrench.

When using a preset-type torque wrench, be sure

to tighten slowly and not to overtighten.

If a bolt makes any noise while you are torquing

it, loosen the bolt and retighten it.

Apply engine oil to the bolt

threads.
6. Install the head cover gasket in the groove of the

cylinder head cover. Seat the recesses for the cam-

shaft first, then work it into the groove around the

outside edges.

NOTE:

Before installing the cylinder head cover gasket,

thoroughly clean the seal and the groove.

When installing, make sure the head cover gasket

is seated securely in the corners of the recesses

with no gap.

7. Apply liquid gasket to the head cover gasket at the

four corners of the recesses.

NOTE:

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

- 0003.

Check that the mating surfaces are clean and dry

before applying liquid gasket.

Do not install the parts if five minutes or more have

elapsed since applying liquid gasket. Instead, reap-

ply liquid gasket after removing old residue.

After assembly, wait at least 30 minutes before

filling the engine with oil.
