Note: During installation and handling of the sensor, follow the parameters listed below:
Do not expose the sensor to any fluids
Do not contact the sensing element when power is applied to the sensor. Contact with the sensing element may result in injury. The sensing element is heated to a minimum of 100° C (212° F).
Do not use any lubricant on any part of the sensor other than the threads. Do not use unapproved thread lubricant. Do not apply more anti-seize to new parts. If more anti-seize is necessary for pre-installation, use only nickel based anti-seize or non-metallic anti-seize. Apply anti-seize to the threads only and avoid contaminating the sensor head.
Do not use sensors that have been dropped or have been exposed to other forms of mishandling. Damage to the sensor may have occurred that is not visible.
Ensure that the sensor is securely mounted.
Remove cover plate assemblies to access the NOx sensor .
Illustration 1 g06042664
Disconnect harness assembly and disconnect sensor cabling (1).
Use 468-8116 Slotted Socket (22mm) to loosen the sensor.
Remove inlet NOx sensor probe (2).
Illustration 2 g06042676
Install NOx sensor probe. Take precautions to prevent damaging the ceramic sensor element (3) when installing.Note: During installation, inspection, and handling of the sensor, follow the parameters listed below:Note: Turn off power supply before disconnecting or connecting the NOx sensor.
Inspect harness for damaged wiring
Inspect for secure connections at all ends of the harness

Replace the sensor if damaged or faulty.Inspection, Reconditioning, or Exchanging of Components
Inspect the following components according to the instructions that are in Cat reusability publications. Refer to Guidelines for Reusable Parts and Salvage Operations, SEBF8029, "Index of Publications on Reusability or Salvage of Used Parts".Recondition the worn components or exchange the components, if necessary. Your Cat dealer can provide these services and components.In addition to the inspection of components, inspect the alignment of the driven equipment. See the Application and Installation Guide for the engine or see the literature that is provided by the OEM of the driven equipment.Oxidation Catalyst
Take proper safety precautions before inspecting the oxidation catalyst.The oxidation catalyst is NOT serviceable. The oxidation catalyst must be replaced if any of the conditions listed below are met.The oxidation catalyst must be inspected to ensure safe and continuous operation of the engine. Failure to identify the conditions listed below, may result in shortened life of the oxidation catalyst and emissions compliance.Inspect for the following conditions:
External housing seam cracking, separation, or damage.
Inlet and Exhaust flange cracking, separation, or damage.
Mounting feet cracking or damage.
Alterations from original manufacturers design.
