SHIPPING POLICY

Tamerx Diesel Products ships via UPS Ground. Next day air shipping can be arranged for a reasonable price of anywhere from $50.00 - $100.00 depending on the weight of the product and your location. 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 2018–2024: OEM 5418649 is an essential component within the diesel aftertreatment system designed for modern Cummins B6.7 engines. The Selective Catalytic Reduction (SCR) system helps manage exhaust emissions by converting nitrogen oxide gases into safer compounds before they leave the exhaust system. Designed for direct compatibility with 2018–2024 Cummins B6.7 platforms, this SCR assembly helps maintain proper exhaust treatment operation in many commercial diesel trucks.

  • The Cummins B6.7 SCR OEM 5418649 functions as part of the exhaust aftertreatment system that processes emissions after combustion.

  • It works with Diesel Exhaust Fluid (DEF) to convert nitrogen oxide gases into nitrogen and water vapor through a catalytic chemical reaction.

  • The SCR assembly is engineered to integrate with other emissions components such as the DOC and DPF within the Cummins B6.7 exhaust system.

  • Built for Cummins B6.7 engines from 2018–2024, this OEM-matched unit supports proper system communication with sensors and DEF dosing equipment.

  • The catalyst housing is designed to handle high exhaust temperatures and continuous exposure to exhaust gases within the aftertreatment assembly.

  • Using the correct OEM 5418649 SCR helps maintain consistent exhaust flow and proper operation of the emissions control system.

For vehicles powered by the Cummins B6.7 engine, a properly functioning SCR assembly plays a critical role in completing the exhaust treatment process. The Cummins B6.7 SCR 2018–2024: OEM 5418649 is designed to match OEM specifications, making it a reliable replacement component for maintaining proper aftertreatment system operation. Customers sourcing dependable emissions system parts can find this SCR solution available through Tamerx Diesel Parts.

The Selective Catalytic Reduction (SCR) system is electronically monitored to ensure proper nitrogen oxide (NOx) reduction and emissions compliance. When a fault occurs, accurate diagnosis is essential to determine whether the issue involves the catalyst, DEF system, or related sensors. Several specialized diagnostic tools are commonly used to evaluate SCR performance.

  • An OEM-compatible scan tool is one of the most important tools for diagnosing SCR problems. It retrieves fault codes, monitors live data, and allows technicians to perform system tests.

  • Diagnostic software can display real-time readings from NOx sensors, temperature sensors, and DEF dosing modules to verify proper operation.

  • A DEF refractometer may be used to test Diesel Exhaust Fluid concentration and confirm correct fluid quality.

  • A multimeter helps check wiring integrity, voltage supply, and sensor communication within the SCR system.

  • Exhaust backpressure testing tools can help determine whether restrictions in the aftertreatment system are affecting performance.

  • Smoke testing equipment may be used to identify exhaust leaks near the SCR housing or related components.

Using the proper diagnostic tools allows technicians to pinpoint SCR-related issues accurately rather than replacing components unnecessarily. Thorough testing helps restore emissions control, prevent engine derate, and ensure the aftertreatment system operates reliably.
