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
towing operation. Towing is in accordance with Towing Procedure Manual at dealer.
●Always attach safety chains before towing.
●When towing, make sure that the transmission, steering system and power train are in good order.
If any unit is damaged, dollies must be used.
●Never tow an automatic transmission model from the rear (that is backward) with four wheels on
the ground. This may cause serious and expensive damage to the transmission.
NISSAN recommends that towing dollies be used when towing your
vehicle beplaced on a flat bed truck as illustrated.
TOWING AN AUTOMATIC TRANSAXLE MODEL WITH FOUR WHEELS ON GROUND
Observe the following restricted towing speeds and distances.
CAUTION:
Never tow an automatic transaxle model from the rear (i.e., backward) with four wheels on the ground
as this may cause serious and expensive damage to the transaxle.

TOWING THE VEHICLE WITH REAR WHEELS RAISED (WITH FRONT WHEELS ON GROUND)
OR FRONT WHEELS RAISED
Never tow the vehicle with rear wheels raised (with front wheels on
ground) or front wheels raised as this may cause serious and expen-
sive damage to the transaxle. If it is necessary to tow it with rear
wheels raised or front wheels raised, always use a towing dolly
under the front wheels.
If the speed or distance must necessarily be greater, remove the
front and rear propeller shafts beforehand to prevent damage to the
transaxle.
Vehicle Recovery (Freeing a stuck vehicle) EAS000FM
●Use the towing hook only, not other parts of the vehicle. Other-
wise, the vehicle body will be damaged.
●Use the towing hook only to free a vehicle stuck in sand, snow,
mud, etc. Never tow the vehicle for a long distance using only
the towing hook.
●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. Never pull on the hook at an angle.
●Stand clear of a stuck vehicle.
WARNING:
●Do not spin the tires at high speed. This could cause them
to explode and result in serious injury. Parts of the vehicle
could also overheat and be damaged.

VALVE GUIDE CLEARANCE
Perform this inspection before removing valve guide.
1. Make sure that the valve stem diameter is within the specification.
2. Push the valve out by approx. 15 mm (0.59 in) toward the combustion chamber side to measure the
valve's run-out volume (in the direction of dial gauge) with dial gauge.
3. The half of the run-out volume accounts for the valve guide
clearance.
VALVE GUIDE REPLACEMENT
When valve guide is removed, replace with oversized [0.2 mm (0.008 in)] valve guide.
1. To remove valve guide, heat cylinder head to 110 to 130°C (230
to 266°F) by soaking in heated oil.
2. Drive out valve guide with a press [under a 20 kN (2 ton, 2.2 US
ton, 2.0 lmp ton) pressure] or hammer and suitable tool.
CAUTION:
Cylinder head contains heat, when working, wear protective
equipment to avoid getting burned.
3. Ream cylinder head valve guide hole.
4. Heat cylinder head to 110 to 130°C (230 to 266°F) by soaking in
heated oil.Standard
Intake : 0.020 - 0.053 mm (0.0008 - 0.0021 in)

21. Using the extension bar [SST: whole length 43 mm (1.69 in)] and
the TORX socket (Q6-E12: commercially available), remove the
mounting bolts, them remove the fuel supply pump toward the
rear of the engine
CAUTION:
Do not disassemble or adjust the fuel supply pump.
22. Remove the fuel supply pump mounting bolts.
NOTE:
The seal washer of the mounting bolts cannot be reused.
CAUTION:
For removal, be careful not to drop the seal washer into the
engine.
23. Remove adjusting shim.
24. Attach a suitable tool in the M8 bolt hole on coupling.
25. Loosen sprocket nut with the TORX wrench (SST).
26. Remove coupling with a suitable puller.
27. Remove fuel supply pump housing.
●Using a hexagon-head wrench [face to face 5mm (0.20in)
SST], remove bolt to remove fuel supply pump housing.
28. Remove O-rings from fuel supply pump housing.

Disassembly and AssemblyEBS00LRX
CAUTION:
Apply new engine oil to parts marked in illustration before installation.
DISASSEMBLY
1. Remove adjusting shims and valve lifters.
●Check the installation positions, and keep them to avoid being
confused.
2. Remove valve.
●Using valve spring compressor, compress valve spring. Using
magnetic hand, remove valve collets.
3. Remove valve spring retainers and valve springs.
4. Remove valves as pressing valve stems toward combustion
chamber.
●Before removing the valve, check the valve guide clearance.
Refer to EM-189, "
Valve Guide Clearance" .
●Check installation positions, and keep them to avoid being
confused.
NOTE:
Refer to the figure for intake and exhaust valve positions.
Intake and exhaust valve driving cams are provided alter-
nately for each camshaft.

Valve Dimension
Check dimensions of each valve. For dimensions, refer to SDS, EM-
221, "Va l v e" .
When valve head has been worn down to 1 mm (0.039 in) in margin
thickness, replace valve.
Grinding allowance for valve stem tip is 0.2 mm (0.008 in) or
less.
Valve Guide Clearance
●Perform the inspection before removing valve guides.
●Check that the valve stem diameter is within specifications.
●Push valve approximately 25 mm (0.98 in) toward combustion
chamber, move valve toward dial indicator to measure valve
movement.
●Valve guide clearance is 1/2 of movement on dial indicator.
●If the measured value exceeds the limit, replace valve guide.
Valve Guide Replacement
When removing valve guide, replace it with oversized [0.2 mm
(0.0008 in)] valve guide.
1. Heat cylinder head to 110 to 130°C (230 to 266°F) in oil bath.
2. Using valve guide drift, tap valve guides out from the combus-
tion chamber side.
CAUTION:
Cylinder head contains heat, when working, wear protective
equipment to avoid getting burned.

8. Tighten the main bearing cap bolts according to the following
procedure:
a. Apply engine oil to the threaded part and seat surface of each
bolt.
b. Tighten to 25 to 30 N·m (2.5 to 3.1 kg-m, 18 to 22 ft-lb) in the
numerical order shown in the figure.
c. Put alignment marks (with paint) on each bolt and the main
bearing cap, all in the same direction. (When using a protractor)
d. Then, tighten 90° to 95° [target: 90°].
●Always use either an angle wrench (SST) or protractor
during angular tightening. Avoid tightening based on
visual checks alone.
●After tightening bolts to specified torque, make sure that
crankshaft rotates smoothly.
●Check crankshaft end side clearance. Refer to EM-210,
"CRANKSHAFT END PLAY" .
9. Check the outer diameter of connecting rod bolts. Refer to EM-
217, "CONNECTING ROD BOLT DEFORMATION" .
10. Install pistons to connecting rod.
a. Using long nose pliers, install snap rings to grooves on piston rear side.
●Fit snap rings correctly into grooves.
b. Install pistons to connecting rods.
●Using industrial dryer, heat pistons up to approx. 60 to 70°C (140 to 158°F) until piston pin can be
pressed down by finger touch. Then insert piston pins into piston and connecting rod from front side of
piston toward rear.
●Assemble piston and connecting rod with front mark of piston
crown and cylinder No. stamped on connecting rod being
positioned as shown in the figure.
c. Install snap rings to front side of pistons.
●Refer to above step a for precaution on snap ring installation.
●After installation, check connecting rods for smooth move-
ment.
11. Use piston ring expander to install piston rings.
CAUTION:
When installing, prevent piston from being damaged.
●Install top ring and second ring with stamped surfaces facing
upward.
●Install rings so that three closed gap position 120° apart one
another.
●Closed gaps do not need to face in a specific directions, as long as each are positioned 120° apart.
