Revision: March 20122013 Infiniti JX
- Be careful not to cut your hand on the insulator edge.

CAUTION:
Use genuine NISSAN exhaust system parts or equivalent, which are specifically designed for heat resistance, corrosion resistance, and shape.

REMOVAL

Remove exhaust system components using power tool.

INSTALLATION

Installation is in the reverse order of removal.
Exhaust Manifold to Exhaust Front Tube





- Install the seal bearing (2) into the front exhaust tube (1).
- When installing the spring (3) and nut (4), ensure the following:
- Make sure the spring (3) sits properly on the flange surface by aligning it to the locator dimples (A).
- Make sure the stud (5) does not contact the inside of the flange bolt hole.

CAUTION:
Be careful not to damage seal bearing surface when installing.
- Compact spring by tightening nut.

CAUTION:
- Ensure springs are seated correctly on the flange and not sitting on locator dimples (A).
- Assemble the seal bearing so that the nut is located in the center of the flare flange hole without contact with the flange.

CAUTION:
- Always replace exhaust gaskets with new ones when reassembling.
- If any insulator is badly deformed, repair or replace it. If deposits such as mud pile up on the insulator, clean and inspect them.
- Temporarily tighten the nuts on the exhaust manifold side and the bolts on the vehicle side. Check each part for interference with other components, and then tighten the nuts and bolts to specification.

INSPECTION AFTER INSTALLATION

- With the engine running, check the exhaust tube joints for exhaust gas leaks and unusual noises.
- Check that the mounting brackets and mounting insulators are installed properly and free from excessive stress. Improper installation could result in excessive noise, leaks, and vibration.
