2005 NISSAN X-TRAIL torque

EX-4
EXHAUST SYSTEM


Temporarily tighten mounting nuts on the exhaust manifold side and mounting bolts on the vehi-
cle side. Check each part for unusual interference, and then tighten them to the specified torque.

When installing each mounting rubber, avoid twisting or unusual extension in up/down and right/
left directions.

Install seal bearings at exhaust front tube and main muffler as follows.
CAUTION:
Do not mix the bolt and spring for seal bearing as the dimension is different for each seal bearing.
Exhaust Front Tube Side (QR20DE and QR25DE)
Insert seal bearing in the direction shown in the figure.
CAUTION:
Tighten mounting bolt without causing interference with
exhaust front tube flange.
Main Muffler Side (QR20DE, QR25DE and YD22DDTi)
Insert seal bearing in the direction shown in the figure.
CAUTION:
Tighten mounting bolt without causing interference with main
muffler flange.
INSPECTION AFTER INSTALLATION

With the engine running, check exhaust tube joints for gas leakage and unusual noises.

Check to ensure that mounting brackets and mounting rubbers are installed properly and free from undue
stress. Improper installation could result in excessive noise and vibration.

CAUTION:
When replacing or cleaning refrigerant cycle components, observe the following.

When the compressor is removed, store it in the same position as it is when mounted on the car.
Malfunction to do so will cause lubricant to enter the low-pressure chamber.

When connecting tubes, always use a torque wrench and a back-up wrench.

After disconnecting tubes, immediately plug all openings to prevent entry of dirt and moisture.

When installing an air conditioner in the vehicle, connect the pipes as the final stage of the opera-
tion. Do not remove the seal caps of pipes and other components until just before required for
connection.

Allow components stored in cool areas to warm to working area temperature before removing seal
caps. This prevents condensation from forming inside A/C components.

Thoroughly remove moisture from the refrigeration system before charging the refrigerant.

Always replace used O-rings.

When connecting tube, apply lubricant to circle of the O-rings shown in illustration. Be careful not
to apply lubricant to threaded portion.

O-ring must be closely attached to dented portion of tube.

When replacing the O-ring, be careful not to damage O-ring and tube.

Connect tube until you hear it click, then tighten the nut or bolt by hand until snug. Make sure that
the O-ring is installed to tube correctly.

After connecting line, conduct leak test and make sure that there is no leakage from connections.
When the refrigerant leaking point is found, disconnect that line and replace the O-ring. Then
tighten connections of seal seat to the specified torque.With gasoline engine

Press clutch disc down by hand.
5. Using the holder to prevent clutch disc rotation.
After tightening the bolt, check that the pulley rotates smoothly.
6. Check clearance around the entire periphery of clutch disc.
If the specified clearance is not obtained, replace adjusting
spacer and readjust.

1. Install field coil.
Be sure to align the coil’s pin with the hole in the compressor’s
front head.
2. Install field coil harness clip using a screwdriver.

Break-In Operation
When replacing compressor clutch assembly, always carry out the break-in operation. This is done by engag-
ing and disengaging the clutch about thirty times. Break-in operation raises the level of transmitted torque.
