We will do everything we can to make sure that you get the service you need. We understand how important it is to receive your order as quickly as possible.
In most cases Tamerx Diesel Products only needs one address, as long as your product is shipping to the same location as your billing information. In order to eliminate credit card fraud, your billing information must match the credit card you provide.

The terms, conditions, and details of our warranty vary from product to product. Specific warranty details can be found below.

Tamerx Diesel Products provides a replacement warranty on all of our parts. The duration and mileage limitations of the warranty vary by product and are specified on the product's detail page/item listing.

Please note that the warranty covers replacement of the part and the cost of shipping the replacement part to you only. It does not cover any shop, labor, towing, or any similar or related costs. This is not a "money back guarantee".

If you experience a problem with your part or it is not functioning properly, the correct warranty procedure is to call us at (510) 257-1777 (8:00 AM - 5:00 PM ET Monday through Friday). Be sure to have your order number and/or other relevant order information ready so we can easily locate your order and resolve your issue as quickly as possible. From that point, we will review with you any troubleshooting steps that may need to be taken and other areas or systems that can be checked to rule out external problems contributing to your part's issue. If a replacement is determined to be necessary, we will then arrange for your replacement part to ship out ASAP and issue any necessary return shipping labels and/or documents.

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.

The Cummins B6.7 SCR 2022–2024, OEM 5418145, is part of the Selective Catalytic Reduction system used in modern B6.7-powered vehicles to manage exhaust emissions. While this OEM number refers to an SCR catalyst module rather than a collection of loose parts, it is made up of several integrated elements that allow it to function effectively within the aftertreatment system.

Below are the primary components and features associated with the Cummins B6.7 SCR OEM 5418145:

  • SCR catalyst substrate
    • The internal honeycomb-style catalyst where nitrogen oxide emissions are chemically treated and converted into nitrogen and water vapor.
  • Catalyst housing
    • A sealed, heat-resistant metal shell that protects the catalyst substrate and directs exhaust flow through the unit.
  • Inlet and outlet connections
    • Flanged or clamped connection points that allow the SCR module to integrate with upstream and downstream exhaust components.
  • Sensor ports
    • Threaded mounting points for emissions and temperature sensors that monitor exhaust conditions and system operation.
  • Mounting brackets and supports
    • Structural elements that secure the SCR module to the vehicle’s exhaust system.

Although OEM 5418145 functions as a single assembled unit, it works in close coordination with other aftertreatment components such as the DEF dosing system, decomposition tube, diesel oxidation catalyst, diesel particulate filter, and emissions sensors. Together, these components ensure proper exhaust treatment and emissions compliance for Cummins B6.7 engines used in 2022–2024 applications.

When your SCR (Selective Catalytic Reduction) system is failing, taking immediate action is essential to avoid engine derates, emissions violations, and costly repairs. SCR issues typically worsen over time, so early diagnosis and correction are critical to protecting the system.

The first step is to check Diesel Exhaust Fluid (DEF) quality. Ensure the DEF meets ISO 22241 standards and has not been contaminated, diluted, or expired. Contaminated DEF is the most common cause of SCR-related fault codes and efficiency failures. If contamination is suspected, the DEF tank and lines should be drained and flushed before further operation.

Next, perform a comprehensive diagnostic scan and inspect upstream engine and emissions components. Midway through troubleshooting, focus on the following key actions:

  • Scan for SCR, NOx sensor, and DEF dosing fault codes
  • Inspect DEF injector and lines for crystallization or blockage
  • Verify NOx sensor accuracy and exhaust temperature readings
  • Check for excessive oil consumption or coolant leaks
  • Confirm proper regeneration events and EGR system operation

After completing these steps, make repairs based on verified root causes rather than repeatedly clearing codes or forcing regens. Many SCR systems are misdiagnosed as failed catalysts when the actual issue lies upstream. Proper diagnostics, correct DEF handling, and timely repairs are the most effective ways to restore SCR performance and prevent repeat failures.

It fits the Cummins B6.7 diesel engine model years 2022 through 2024.

It is the selective catalytic reduction unit used in the exhaust aftertreatment system.
