As is the case for the majority of the diesel products sold on Tamerx Diesel Products, your part's warranty is active as soon as you install it. In some other cases, warranty activation is contingent upon you sending us your core (i.e., your old part). Tamerx Diesel Products will provide you a return shipping label for parts that have a warranty with a core return condition. When we have received your core return, the part's warranty coverage begins. We reserve the right to void the product warranty if your core is not received within the allotted time, or if it isn't received at all. If the warranty for the diesel part you are purchasing has a core return requirement, it will be clearly noted on the product detail page/item listing.
What is a Core Charge?
A core charge (also called "core deposit") is similar to the deposit you might pay for a can or bottle of soda and is a standard requirement in the auto parts industry. For example, in many states, to promote recycling, you pay a deposit when you purchase a can of soda and receive your deposit back when you return the empty can. Many automotive parts have a core charge, or core price, that works in essentially the same way as a soda can deposit.
30 Day Core Charge Hold
You authorize Tamerx Diesel Products, to hold your credit card for the specified core charge amount and that you agree to return your core with 30 days of receiving the purchased part. When we have received your core return, the hold is released and the core charge payment is canceled.
The customer, or parts buyer, is responsible for any shipping costs associated with core returns unless otherwise specified in the product listing/detail page. Tamerx Diesel Products offers prepaid UPS shipping labels (SKU numbers UPS-CR1 and UPS-CR2) for use in returning your core that are available for purchase on our website during your shopping/order process.
The shipping label you will need to use for the core return is dependent upon what part you are purchasing. UPS-CR1 is good for cores weighing up to 20 pounds. UPS-CR2 is appropriate for shipping cores weighing 21 pounds or more. You must include enough information with the core return that clearly identifies it as a.) a Core Return, and b.) contains enough information we can use to clearly associate the core return with your order. Including a copy of the invoice or packing slip that came with the original shipment, clearly marked "Core Return", is ideal. Alternately, you can include a note marked as "Core Return" that includes your order number, full name and address, and phone number or other contact information. Failure to include this information with your returned core will most likely delay any due core credit being issued and/or delay any applicable warranty activation. Core returns need to be for the exact part purchased and cannot be damaged. Substituting another part in place of the part you have purchased is not acceptable.
All fluids must be drained.
If you have purchased a set or a parts package, you will need to return cores for all components of the set. For example, if you have purchaed a high pressure oil pump with an IPR valve, you will need to return both HPOP and IPR valve cores to receive proper credit. If you have purchased an EGR cooler/EGR valve package, your core return must consist of an EGR cooler core and an EGR valve core, or core credit will not be given.
Core Charges are often mandated by state legislature, and, as such, the actual core charge and taxes on the charge may vary depending on the state in which you buy your part. The Tamerx Diesel Products core charge presented to you online today with your item is representative of the most common core charge.

Here’s a clear breakdown of the components of the Cummins X15 SCR 2018–2024: OEM 5417986 (a Selective Catalytic Reduction unit used in the aftertreatment system of Cummins X15 engines):
The OEM 5417986 unit itself is typically referred to as an outlet catalyst module in Cummins documentation, which means it’s one of the main catalyst housings that treats exhaust gases as part of the SCR process.
Core Components Inside an SCR Assembly
While the exact internal sub-parts for this specific OEM don’t appear in public parts listings, SCR systems like 5417986 generally include the following functional elements:
- SCR Catalyst Brick/Monolith
- The core ceramic or metallic honeycomb structure coated with catalyst materials that facilitate the chemical reduction of nitrogen oxides (NOx) into harmless compounds. (
- Housing/Canister
- A robust metal casing that contains the catalyst substrate and protects it from the exhaust environment while directing flow correctly.
- Sensor Bungs / Ports
- Mounting locations for emissions sensors (e.g., NOx sensors, temperature probes) that provide feedback to the aftertreatment control system; some units shift between 2- and 3-bung configurations depending on the design.
- Inlet and Outlet Flanges
- Connection points for the exhaust flow into and out of the SCR unit, sealing gaskets, and fasteners.
Related Aftertreatment Components (System-Level)
Although not inside the 5417986 module itself, the SCR system depends on other major parts upstream/downstream such as:
- DEF (Diesel Exhaust Fluid) dosing system
- injects urea solution into exhaust before entering the catalyst
- Control module / ECM communication harness
- manages dosing based on sensor feedback
- Temperature and NOx sensors
- monitor conditions for proper catalytic reaction
In summary, OEM 5417986 is a key SCR catalyst housing that includes the catalyst substrate and necessary mounting features for sensors and exhaust connections. It works with the broader SCR aftertreatment system to help manage NOx in Cummins X15 engines.
Prolonging the lifespan of your SCR (Selective Catalytic Reduction) system depends on consistent maintenance, proper operating habits, and early problem detection. SCR components are designed to last for many years, but neglect and contamination can significantly shorten their service life.
The most important step is maintaining high-quality Diesel Exhaust Fluid (DEF). Always use DEF that meets ISO 22241 standards, store it in sealed containers away from heat and sunlight, and avoid topping off with questionable fluid. Contaminated or degraded DEF is the leading cause of SCR damage and efficiency faults.
Equally important is monitoring engine and emissions health. Addressing minor issues early prevents long-term catalyst damage. Focus on the following best practices during regular service intervals:
- Use only clean, certified DEF and dedicated filling equipment
- Keep the DEF tank, lines, and injector free from crystallization
- Repair EGR, turbo, or fuel system issues promptly
- Monitor oil consumption and coolant levels
- Avoid excessive idling and frequent short trips
- Respond quickly to emissions-related warning lights
Lastly, perform routine diagnostics even when no warning lights are present. Tracking NOx sensor data, exhaust temperatures, and regeneration performance helps identify trends before failure occurs. When SCR efficiency codes appear, avoid repeated resets and forced regens without diagnosis. Preventive maintenance and correct operating habits are the most effective ways to maximize SCR lifespan and reduce the risk of expensive emissions repairs.
It works with the DEF dosing system to chemically reduce nitrogen oxides in the exhaust stream.
Yes, it’s built to meet the durability expectations of the original exhaust aftertreatment system.
Yes, scanning and calibration may be required to ensure proper communication with the engine control module.
Yes, it is designed to integrate with the factory sensors and wiring harnesses on supported X15 engines.
