2001 NISSAN PICK-UP fuel tank removal

2. Disconnect the fuel hoses from the fuel injection pump.
3. Disconnect the harness connector from the fuel injection
pump.
+Disconnect the connector by pulling the connector stopper
fully.
+When the stopper is fully pulled, the connector will be dis-
connected together. For installation, push the connector half
way first, then press the stopper until it locks, so that the
connector is connected together.
4. Remove the fuel injection pump rear bracket.
5. Remove the front chain case.
+Move the power steering fluid reservoir tank from the bracket.
+Loosen and remove the mounting bolts in the reverse order
of the numbers shown in the figure.
+As for bolts 6, 10, and 11, remove with rubber washer
because there is not enough space for removing only the
bolts.
CAUTION:
To prevent foreign objects from getting in the engine, cover
the opening during the removal of the front chain case.
6. Adjust the No. 1 cylinder to the top dead center position.
+Turn the crankshaft pulley clockwise, then align the align-
ment mark (punched mark) of the camshaft sprocket to the
position shown in the figure.
+There is no indicator on the crankshaft pulley.
+It is not necessary to mark the secondary timing chain for
removal because it can be matched by the link color for
installation. However, the alignment mark on the fuel injec-
tion pump sprocket is difficult to see; mark it if necessary.
7. Remove the chain tensioner.
a. Push the plunger of the chain tensioner, then fix it with a tool
such as a push pin.
b. Using the hexagon wrench (face to face: 5 mm) (SST),
remove the mounting bolts, then remove the chain tensioner.
+A multi-purpose tool may also be used.

Bulb Replacement
The headlamp is a semi-sealed beam type which uses a replace-
able halogen bulb. The bulb can be replaced from the engine
compartment side without removing the headlamp body.
+Grasp only the plastic base when handling the bulb.
Never touch the glass envelope.
1. Disconnect the battery cable.
2. Disconnect the harness connector from the back side of the
bulb.
3. Pull off the rubber cap.
4. Push and raise retaining pin to loosen it.
5. Remove the headlamp bulb carefully. Do not shake or rotate
the bulb when removing it.
6. Install in the reverse order of removal.
CAUTION:
Do not leave headlamp reflector without bulb for a long
period of time. Dust, moisture, smoke, etc. entering head-
lamp body may affect the performance of the headlamp.
Remove headlamp bulb from the headlamp reflector just
before a replacement bulb is installed.
Aiming Adjustment
When performing headlamp aiming adjustment, use an aiming
machine, aiming wall screen or headlamp tester. Aimers should
be in good repair, calibrated and operated in accordance with
respective operation manuals.
If any aimer is not available, aiming adjustment can be done as
follows:
For details, refer to the regulations in your own country.
a. Keep all tires inflated to correct pressures.
b. Place vehicle and tester on one and same flat surface.
c. See that there is no-load in vehicle (coolant, engine oil
filled up to correct level and full fuel tank) other than the
driver (or equivalent weight placed in driver's position).
CAUTION:
Be sure aiming switch is set to ª0º when performing aiming
adjustment on vehicles equipped with headlamp aiming
control.

6. Remove front chain case.
+Move power steering fluid reservoir tank from the bracket.
+Loosen fixing bolts in the reverse order of that shown in the
figure and remove them.
+Remove all bolts with the rubber washer as space is limited
for pulling them out.
CAUTION:
+While front chain case is removed, cover openings to
prevent entry of foreign material into engine.
+Do not remove two mass dampers on the back of cover.
7. Set the No. 1 piston to TDC on its compression stroke.
+Turn crankshaft pulley clockwise so that the alignment mark
(punched mark) on each camshaft sprocket is positioned as
shown in the figure.
+No position indicator is provided on the crankshaft pul-
ley.
+When installing, color coded links on the secondary tim-
ing chain can be used as alignment marks. Marking may
not be necessary for removal; however, make alignment
marks as required because the alignment mark on fuel
injection pump sprocket may not be easy to see.
8. Remove chain tensioner.
a. Push the plunger of chain tensioner and keep it pressed with
a push pin.
b. Using a hexagon-head wrench [face to face: 5 mm (0.20 in),
SST], remove bolts to remove chain tensioner.
