Emergency Towing

This is the best way of
transporting the vehicle.

1-12General Information
Towing
A
B D
C
If the vehicle needs to be towed, call a professional
towing service. Never tow the vehicle behind another
vehicle with a rope or chain. It is very dangerous.
There are three popular methods of towing a vehicle.
The operator loads the vehicle
on the back of a truck.
To accommodate flat-bed equipment, the vehicle is
equipped with front towing hooks (A), front tie down
hook slots (B), rear towing hook (C), and rear tie down
hook slots (D).
The rear towing hook can be used with a winch to pull
the vehicle onto the truck, and the tie down hook slots
can be used to secure the vehicle to the truck.

Wheel Lift Equipment
This is an acceptable way of towing the
vehicle.
Sling-type Equipment
This method of towing
the vehicle is unacceptable.
Manual Transmission
Automatic Transmission
1-13
The tow truck uses two
pivoting arms that go under the tires (front or rear) and
lift them off the ground. The other two wheels remain
on the ground.
The tow truck uses metal
cables with hooks on the ends. These hooks go around
parts of the frame or the suspension, and the cables lift
that end of the vehicle off the ground. The vehicle’s
suspension and body can be seriously damaged if this
method of towing is attempted.
If the vehicle cannot be transported by a flat-bed, it
should be towed with the front wheels off the ground. If
the vehicle is damaged, and must be towed with the
front wheels on the ground, or with all four wheels on
the ground, do this:
 Release the parking brake.
 Shift the transmission to neutral.
 Leave the ignition switch in ACCESSORY (I) so the steering wheel does not lock.
 Make sure all accessories are turned off to minimize current battery draw.
 Release the parking brake.
 Start the engine.
 Shift to D, then to N.
 Turn off the engine.
 Leave the ignition switch in ACCESSORY (I) so the steering wheel does not lock.
 Make sure all accessories are turned off to minimize current battery draw.
It is best to tow the vehicle no farther than 80 km
(50 miles), and keep the speed below 55 km/h (35 mph).  Improper towing preparation will damage the
transmission. Follow the above procedure exactly. If
you cannot shift the transmission or start the engine
(automatic transmission), the vehicle must be
transported on a flat-bed.
 Trying to lift or tow the vehicle by the bumpers will cause serious damage. The bumpers are not
designed to support the vehicle’s weight.

Ignition Timing Inspection

1. Connect the Honda Diagnostic System (HDS) to the data link connector (DLC) (see step 2 on page 11-3).
2. Turn the ignition switch to ON (II).
3. Make sure the HDS communicates with the vehicle and the engine control module (ECM)/powertrain
control module (PCM). If it does not communicate,
troubleshoot the DLC circuit (see page 11- 204).
4. Check for DTCs (see page 11-3). If a DTC is present, diagnose and repair the cause before continuing
with this test.
5. Start the engine. Hold the engine speed at 3,000 rpm with no load (in N or P (A/T model) or
neutral (M/T model)) until the radiator fan comes
on, then let it idle.
6. Check the idle speed (see page 11-309).
7. Jump the SCS line with the HDS.
8. Connect the timing light to the service loop (white tape). 9. Aim the light toward the pointer (A) on the cam
chain case. Check the ignition timing under a no
load condition (headlights, blower fan, rear window
defogger, and air conditioner are turned off).
10. If the ignition timing differs from the specification, check the cam timing. If the cam timing is OK,
update the ECM/PCM if it does not have the latest
software (see page 11-227), or substitute a known-
good ECM/PCM (see page 11-7), then recheck. If the
system work properly, and the ECM/PCM was
substituted, replace the original ECM/PCM
(see page 11-228).
11. Disconnect the HDS and the timing light.

1. Inspect the valve stem-to-guide clearance (see page 6-55).
2. As illustrated, use a commercially available air- impact valve guide driver (A) modified to fit the
diameter of the valve guides. In most cases, the
same procedure can be done using the valve guide
driver and a conventional hammer.
3. Select the proper replacement guides, and chill them in the freezer section of a refrigerator for at
least an hour.
4. Use a hot plate or oven to evenly heat the cylinder head to 150 °C (300 °F). Monitor the temperature
with a cooking thermometer. Do not get the head
hotter than 150 °C (300 °F); excessive heat may
loosen the valve seats. 5. Working from the camshaft side, use the driver and
an air hammer to drive the guide about 2 mm
(0.1 in.) towards the combustion chamber. This will
knock off some of the carbon and make removal
easier. Hold the air hammer directly in line with the
valve guide to prevent damaging the driver.
6. Turn the head over, and drive the guide out toward the camshaft side of the head.
7. If a valve guide won’t move, drill it out with a 8 mm (5/16 in.) bit, then try again.
NOTE: Drill guides only in extreme cases, you
could damage the cylinder head if the guide breaks.
8. Remove out the new guide(s) from the freezer, one at a time, as you need them.

5. Install the valve spring and the spring retainer.Place the end of the valve spring with the closely
wound coils toward the cylinder head.
6. Install the valve spring compressor attachment and the valve spring compressor. Compress the valve
spring, and install the valve cotters.
7. Remove the valve spring compressor and the valve spring compressor attachment.
8. Lightly tap the end of each valve stem two or three times with a plastic mallet (A) to ensure proper
seating of the valve and valve keepers. Tap the
valve stem only along its axis so you do not bend
the stem. 1. Reassemble the rocker arm assembly (see page
6-46).
2. Clean and dry the No. 5 rocker shaft holder mating surface.
3. Apply liquid gasket, P/N 08717-0004, 08718-0001, 08718-0003, or 08718-0009, evenly to the cylinder
head mating surface of the No. 5 rocker shaft
holder. Install the component within 5 minutes of
applying the liquid gasket.
NOTE: If you apply liquid gasket P/N 08718-0012, the component must be install within 4 minutes.
 If too much time has passed after applying the liquid gasket, remove the old liquid gasket and
residue, then reapply new liquid gasket.
4. Insert the bolts (A) into the rocker shaft holder, then install the rocker arm assembly (B) on the cylinder
head.
Apply liquid gasket
along the broken line.

Connecting Rod and Crankshaft End Play Inspection
1. Remove the oil pump (see page 8-16).
2. Remove the baffle plates (see step 8 on page 7-13).
3. Measure the connecting rod end play with a feeler
gauge between the connecting rod and the
crankshaft.
4. If the connecting rod end play is beyond the service limit, install a new connecting rod, and recheck. If it
is still beyond the service limit; replace the
crankshaft (see page 7-13). 5. Push the crankshaft firmly away from the dial
indicator, and zero the dial against the end of the
crankshaft. Then pull the crankshaft firmly back
toward the indicator, the dial reading should not
exceed the service limit.
6. If the end play is beyond the service limit, replace the thrust washers and recheck. If it is still beyond
the service limit, replace the crankshaft (see page
7-13).

Crankshaft Main Bearing Replacement
1. To check the main bearing-to-journal oil clearance,
remove the lower block and the bearing halves
(see page 7-13).
2. Clean each main journal and bearing half with a clean shop towel.
3. Place one strip of plastigage across each main journal.
4. Reinstall the bearings and lower block, then tighten the bolts to 29 N·m (3.0 kgf·m, 22 lbf·ft) 56 ° in
thepropersequence(seestep19onpage7-27).
NOTE: Apply new engine oil to the bolt threads and flanges.
 Do not rotate the crankshaft during inspection.
5. Remove the lower block and the bearings again, and measure the widest part of the plastigage. 6. If the plastigage measures too wide or too narrow,
remove the crankshaft, and remove the upper half
of the bearing. Install a new, complete bearing with
the appropriate color code(s), and recheck the
clearance. Do not file, shim, or scrape the bearings
or the caps to adjust clearance.
7. If the plastigage shows the clearance is still incorrect, try the next larger or smaller bearing (the
color listed above or below the current one), and
check again. If the proper clearance cannot be
obtained by using the appropriate larger or smaller
bearings, replace the crankshaft, and start over.
