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.

Taking care of your Caterpillar One Box (OEM 470-0246) is all about maintaining the entire aftertreatment system as a whole—not just a single component. Since the “One Box” combines multiple emissions components (like DOC, DPF, and SCR) into one unit, proper care is essential to keep everything working together efficiently.
Because it handles high heat, soot, and chemical reactions, neglect can quickly lead to buildup or system issues.
Here’s how to keep it in good condition:
- Stick to regular maintenance intervals
Following scheduled service is critical. Maintenance schedules are designed to prevent buildup and ensure all emissions components function properly. - Avoid excessive idling
Long idle periods reduce exhaust temperature, which can lead to soot accumulation inside the system. - Use proper fuel and DEF quality
Clean fuel and high-quality Diesel Exhaust Fluid help prevent contamination that can damage internal components. - Monitor for warning lights or fault codes
The system relies on sensors—any alerts should be addressed immediately to avoid bigger issues. - Allow proper regeneration cycles
The system needs to periodically burn off soot. Interrupting regeneration too often can cause clogging. - Inspect for leaks or external damage
Check connections and housing for cracks, leaks, or loose fittings that could affect operation. - Keep supporting systems in check
Engine condition directly affects the One Box. Issues like poor combustion or injector problems can increase soot and strain the system.
In simple terms, taking care of the Caterpillar 470-0246 means maintaining clean inputs, allowing proper system cycles, and staying proactive with inspections—so the entire emissions system continues to operate smoothly and reliably.
A One Box system integrates multiple emissions components—such as the DOC, DPF, and SCR—into a single unit, making it highly efficient but also more sensitive to system imbalances. The most common cause of failure is excessive internal buildup, typically from soot, ash, or DEF-related deposits.
Because all components work together inside one housing, a problem in one area can quickly affect the entire system.
Several factors contribute to One Box failure:
- Soot and ash accumulation
- Over time, particles can build up inside the system, restricting airflow and reducing overall efficiency.
- DEF crystallization and deposits
- Improper DEF decomposition can lead to residue forming within the SCR section, which may impact the entire unit.
- Imbalanced operating conditions
- If the system doesn’t reach proper temperatures, it can prevent regeneration and increase internal buildup.
- Faulty sensors or dosing issues
- Incorrect readings or improper DEF injection can disrupt system performance and lead to uneven deposits.
- Lack of routine maintenance
- Without regular inspection, small issues can develop into larger restrictions affecting multiple components.
Understanding these causes is important because a failure in a One Box system often involves more than one issue. Staying proactive with maintenance and addressing early warning signs can help prevent widespread system problems.
It is engineered for continuous use in high-temperature, high-load environments typical of construction and heavy equipment applications.
By integrating multiple emissions control stages, it helps equipment meet strict environmental standards for exhaust emissions.
Yes, proper operation ensures stable exhaust conditions, which allows sensors to provide accurate data for system monitoring.
Using the correct OEM unit ensures proper fitment, correct emissions processing characteristics, and compatibility with Caterpillar equipment systems.
