CYLINDER HEAD DISTORTION
Warpage of surface:
Less than 0.1 mm (0.004 in)
If beyond the speci®ed limit, replace it or resurface it.
Resurfacing limit:
The resurfacing limit of cylinder head is determined by the
cylinder block resurfacing in an engine.
Amount of cylinder head resurfacing is ``A''.
Amount of cylinder block resurfacing is ``B''.
The maximum limit is as follows:
A + B = 0.1 mm (0.004 in)
Nominal cylinder head height:
139.9 - 140.1 mm (5.508 - 5.516 in)
VALVE GUIDE CLEARANCE
1. Insert the valve stem into the valve guide and move it back,
forth and slide it.
If valve stem makes a clatter and moves back and forth exces-
sively out of line, or if it does not slide well, replace valve or
valve guide, or both.
2. Install valve stem into the valve guide.
3. Measure the de¯ection.
Stem to guide de¯ection limit:
0.1 mm (0.004 in)
(Half of dial gauge reading)
4. If it exceeds the limit, check valve to valve guide clearance.
(1) Measure valve stem diameter and guide inner diameter.
(2) Check that clearance is within the speci®cation.
Valve to valve guide clearance limit:
0.1 mm (0.004 in)
(3) If it exceeds the limit, replace valve or valve guide.
VALVE GUIDE REPLACEMENT
1. Heat cylinder head 150 to 160ÉC (302 to 320ÉF) in oil.
2. Remove the guide with suitable tool.

Amount of cylinder block resurfacing is ``B''.
The maximum limit is as follows:
A + B = 0.2 mm (0.008 in)
Nominal cylinder block height

TOE-IN
Measure toe-in using the following procedure.
WARNING:
+Always perform the following procedure on a ¯at surface.
+Make sure that no person is in front of the vehicle before
pushing it.
1. Bounce front of vehicle up and down to stabilize the posture.
2. Push the vehicle straight ahead about 5 m (16 ft).
3. Put a mark on base line of the tread (rear side) of both tires at
the same height of hub center. This mark is a measuring point.
4. Measure distance ``A'' (rear side).
5. Push the vehicle slowly ahead to rotate the wheels 180 degrees
(1/2 turn).
If the wheels have rotated more than 180 degrees (1/2 turn), try
the above procedure again from the beginning. Never push
vehicle backward.
6. Measure distance ``B'' (front side).
Total toe-in:
Refer to SDS (FA-27).
7. Adjust toe-in by varying the length of steering tie-rod.
(1) Loosen lock nuts.
(2) Adjust toe-in by screwing tie-rod in and out.
Make sure both tie-rods are the same length.
(3) Tighten lock nuts to speci®ed torque.
Lock nut tightening torque:
Refer to ST section (``POWER STEERING GEAR
AND LINKAGE'').
FRONT WHEEL TURNING ANGLE
Turning angle is set by stroke length of steering gear rack and
cannot be adjusted.
1. Set wheels in straight-ahead position. Then move vehicle for-
ward until front wheels rest on turning radius gauge properly.
2. Rotate steering wheel all the way right and left; measure turn-
ing angle.
Do not hold the steering wheel on full lock for more than 15
seconds.
Wheel turning angle (Full turn):
Refer to SDS (FA-27).
3. Adjust by stopper bolt if necessary.

IDENTIFICATION INFORMATION
GI-38

Tow Truck Towing
CAUTION:
+All applicable local laws regarding the towing operation
must be obeyed.
+It is necessary to use proper towing equipment to avoid
possible damage to the vehicle during a towing operation.
+Attach safety chains for all towing.
+When towing, make sure that the transmission, steering
system and power train are in good order. If any unit is
damaged, a dolly must be used.
+When towing with the front wheels on the ground:
Turn the ignition key to the ``OFF'' position and secure the
steering wheel in a straight-ahead position with a rope or
similar device. Never place the ignition key in the ``LOCK''
position. This will result in damage to the steering lock
mechanism.
+When towing manual transmission models with the rear
wheels on the ground:
Release the parking brake and move the gearshift lever to
neutral (``N'' position).
+For 4-wheel drive models:
Set the manual-lock free-running hubs to the free position and
2-way lock free-running hubs to the auto position. (See
``
Transfer case shifting procedures for 4-wheel drive
vehicles'' in ``Starting and driving'' section.) Move the transfer
case shift lever into the ``2H'' position and the transmission shift
lever into the neutral (``N'') position.
Do not shift the transfer lever to the ``4L'' position. This will
cause damage to the transmission.
NISSAN recommends that a dolly be used as illustrated.
If you have to tow a manual transmission model with front
wheels raised (with rear wheels on ground)
Observe the following restricted raising heights.
+Do not raise the front end over!.
Wagon
!= 600 mm (23.62 in)
Hardtop
!= 500 mm (19.69 in)

LIFTING POINTS AND TOW TRUCK TOWING

If you have to tow an automatic transmission model
with four wheels on ground or tow an automatic
transmission model with front wheels raised (with rear
wheels on ground)
Observe the following restricted towing speeds, distances and rais-
ing heights.
+Speed: Below 50 km/h (30 MPH)
+Distance: Less than 65 km (40 miles)
+Do not raise the front end over!.
Wagon
!= 600 mm (23.62 in)
Hardtop
!= 500 mm (19.69 in)
If the speed, distance or height must necessarily be greater,
remove the propeller shaft beforehand to prevent damage to the
transmission.
CAUTION:
+Never tow your vehicle from the rear (i.e., backward) with
four wheels on the ground as this may cause serious and
expensive damage to the transmission.
+Be sure to place the transfer case shift lever into the ``2H''
position and the transmission shift lever into the neutral
(``N'') position if the vehicle is to be towed.
TOWING HOOKS
The towing hooks are provided only for emergency.
+Use the towing hooksonly, not other parts of the vehicle.
Otherwise, the vehicle body will be damaged.
+Use the towing hooksonlyto free a vehicle stuck in sand,
snow, mud, etc.Nevertow the vehicle for long distances using
only the towing hooks.
+The towing hook is under tremendous force when used to free
a stuck vehicle. Always pull the cable straight out from the front
or rear of the vehicle.Neverpull on the hook at a sideways
angle.
