2. Move the following parts.
+TDC sensor harness
+Power steering oil pump
3. Remove the chain cover.
+Remove the holding bolts A to C shown in the figure.
CAUTION:
While the chain cover is removed, be careful not to allow
entry of dust or foreign objects.
4. Set the No. 1 cylinder to the TDC.
1) Turn the crankshaft pulley clockwise, and match the timing
indicator of the gear case to the timing mark of the crankshaft
pulley.
2) Make sure that the cam sprocket match mark is in the posi-
tion shown in the figure.
+If the match mark is not in position, turn the crankshaft pul-
ley once more and position it.
+When removing at No. 1 cylinder TDC, each sprocket and
chain is fitted using the match mark, therefore there is no
need to apply any match marks beforehand.
5. Remove the chain tensioner.
1) Loosen upper and lower holding bolts.
2) Holding the chain tensioner in your hand, remove the upper
holding bolt and release the spring tension.
3) Remove the lower holding bolt, then remove the chain ten-
sioner.
+The chain tensioner does not have a mechanism which pre-
vents the ejection of the plunger. (It does have a mechanism
which prevents the plunger from returning.)
CAUTION:
Be careful not to drop the plunger and spring.

Inspection
+When the camshaft or parts in connection with valves are
removed or replaced, and a fault has occurred (poor starting,
idling, or other faults) due to the misadjustment of the valve
clearance, inspect as follows.
+Inspect and adjust when the engine is cool (at normal tem-
perature).
+Be careful of the intake and exhaust valve arrangement. (The
valve arrangement is different from that in a normal engine.)
(The camshafts have, alternately, either an intake valve or an
exhaust valve.)
1. Remove the following parts.
+Intercooler cover
+Intercooler
+Rocker cover
2. Set the No. 1 cylinder at TDC.
1) Rotate the crankshaft pulley clockwise, and align the TDC
mark of the crankshaft pulley with the timing indicator of the
TDC sensor bracket.
2) Confirm that the cam nose of the No. 1 cylinder and the
knock pin of the cam sprocket is in the position shown in the
figure.
+Rotate the crankshaft pulley again if not in the position shown
in the figure.
3. While referring to the figure, measure the valve clearance in
the circled area of the table below.

sprocket with No.1 cylinder being positioned at TDC. Refer
to the figure.
Refer to ªTIMING CHAINº, EM-1027.
CAUTION:
After removing timing chain, never rotate crankshaft, or the
piston will push the valve up and damage the valve.
+Do not paint the match mark on the timing chain beforehand
as the No. 1 cylinder is set at the TDC during assembly.
5. Remove the TDC sensor.
CAUTION:
+Do not drop or hit the sensor.
+Store in a clean place free of iron filings, etc.
+Do not place near any magnetic equipment.
6. Remove the water pump and its stud bolts.

CAUTION:
Apply the liquid gasket around the bolt holes shown by the
arrows in the figure.
5) Install the gear case.
+Insert the gear case diagonally to prevent it from dragging
over the liquid gasket applied on the timing gear case and the
oil pan (upper).
+Align the dowel pin at the lower position of cylinder block with
the hole on the gear case side.
+Tap the area around the dowel pin with a plastic hammer if
it cannot be inserted easily.
CAUTION:
Do not pop out the O-rings.

Dimension below neck:
A: 25 mm (0.98 in)
B: 30 mm (1.18 in)
C: 50 mm (1.97 in)
D: 80 mm (3.15 in)
E: 20 mm (0.79 in)
7) Install the holding bolts from the rear side of the front plate.
6. Install the crankshaft pulley.
+Insert by aligning the 2 sides of the oil pump with the 2 sides
of the shaft on the rear side of the crankshaft pulley.
CAUTION:
Do not damage the oil seal lip when inserting.
+Refer to EM-1041, ªRemovalº for the crankshaft setting pro-
cedures when tightening the holding nut.
7. Install the water pump.
+Install it before installing the TDC sensor. Refer to ªWater
Pumpº in LC section.
8. Install the TDC sensor.
+Align the bracket knock pin with the hole on the gear case
side and tighten the holding bolt.
+Confirm that the clearance between the end of the sensor
and the signal detection protrusion of the crankshaft pulley is
within the specification.
Standard: 1 0.8 mm (0.039 0.031 in)
+Arrange the TDC sensor harness to the position shown in the
figure.
CAUTION:
Confirm that the harness has no deflection around the

Supplemental Restraint System (SRS) ªAIR
BAGº and ªSEAT BELT PRE-TENSIONERº
The Supplemental Restraint System such as ªAIR BAGº and ªSEAT BELT PRE-TENSIONERº used along
with a seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain
types of collision. The SRS system composition which is available to NISSAN MODEL Y61 is as follows (The
composition varies according to the destination and optional equipment.):
+For a frontal collision
The Supplemental Restraint System consists of driver air bag module (located in the center of the
steering wheel), front passenger air bag module (located on the instrument panel on passenger side),
seat belt pre-tensioners, a diagnosis sensor unit, warning lamp, wiring harness and spiral cable.
+For a side collision
The Supplemental Restraint System consists of front side air bag module (located in the outer side of
front seat), satellite sensor, diagnosis sensor unit (one of components of air bags for a frontal collision),
wiring harness, warning lamp (one of components of air bags for a frontal collision).
Information necessary to service the system safely is included in theRS sectionof this Service Manual.
WARNING:
+To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance should be per-
formed by an authorized NISSAN dealer.
+Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and
Air Bag Module, see the RS section.
+Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. Spiral cable and wiring harnesses covered with yellow insulation tape either just
before the harness connectors or for the complete harness are related to the SRS.
Precautions for Fuel
DIESEL ENGINE*:
Diesel fuel of at least 50 cetane for ZD30DDTi engine
* If two types of diesel fuel are available, use summer or win-
ter fuel properly according to the following temperature con-
ditions.
+Above þ7ÉC (20ÉF) ... Summer type diesel fuel.
+Below þ7ÉC (20ÉF) ... Winter type diesel fuel.
CAUTION:
+Do not use home heating oil, gasoline, or other alternate
fuels in your diesel engine. The use of those can cause
engine damage.
+Do not use summer fuel at temperature below þ7ÉC
(20ÉF). The cold temperature will cause wax to form in
the fuel. As a result, it may prevent the engine from run-
ning smoothly.
+Do not add gasoline or other alternate fuels to diesel
fuel.

+Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. Spiral cable and wiring harnesses covered with yellow insulation tape either just
before the harness connectors or for the complete harness are related to the SRS.
Precautions for Refrigerant Connection
A new type refrigerant connection has been introduced to all refrigerant lines except the following location.
+Expansion valve to cooling unit
FEATURES OF NEW TYPE REFRIGERANT CONNECTION
+The O-ring has been relocated. It has also been provided with a groove for proper installation. This elimi-
nates the chance of the O-ring being caught in, or damaged by, the mating part. The sealing direction of the
O-ring is now set vertically in relation to the contacting surface of the mating part to improve sealing char-
acteristics.
+The reaction force of the O-ring will not occur in the direction that causes the joint to pull out, thereby
facilitating piping connections.
