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.
Supporting proper airflow and combustion within the engine system, the Cummins ISB 6.7L-220 Turbo Assembly (OEM 4352330RX) is designed for compatibility with select Cummins ISB 6.7L-220 diesel engine applications. This turbo assembly uses exhaust-driven turbine energy to compress incoming air, allowing for efficient combustion within the engine. Manufactured to meet original equipment specifications, it is engineered for accurate fitment and dependable integration with existing intake and exhaust components. Turbochargers are a critical part of modern diesel engines, helping regulate airflow and maintain consistent engine operation under varying load conditions. The durable construction is built to withstand high temperatures and demanding operating environments commonly found in heavy-duty diesel applications. Replacing a worn or failing unit with the OEM 4352330RX turbo assembly helps maintain proper airflow and supports reliable engine function.

In modern diesel engines like the Cummins ISB 6.7L-220, airflow management is essential for efficient combustion. The OEM 4352330RX turbo assembly is designed to regulate how air enters the engine by using exhaust energy to drive a continuous cycle of air compression.
Rather than relying on external input, this system harnesses what the engine already produces—exhaust gases—to improve airflow dynamics inside the engine.
Understanding How the Turbo Assembly Operates
- Exhaust energy drives the turbine
- Hot exhaust gases exit the engine and spin a turbine wheel inside the turbo housing.
- Linked compressor pulls in fresh air
- The turbine is connected to a compressor wheel, which draws in outside air as it spins.
- Air is compressed and directed inward
- The incoming air is compressed, increasing its density before entering the intake system.
- Airflow is adjusted based on engine demand
- The system responds to changes in engine speed and load, ensuring proper airflow at all times.
- Compressed air enters the combustion chamber
- The denser air mixes with fuel, allowing for a more controlled combustion process.
Why This System Matters
The Cummins ISB 6.7L-220 Turbo Assembly OEM 4352330RX plays a central role in maintaining balanced airflow throughout engine operation. By converting exhaust energy into usable air compression, it helps ensure the engine receives the right amount of air for combustion across different working conditions.
Turbo assemblies are built to handle extreme conditions, operating under high heat and rapid rotation to support proper airflow into the engine. Over time, however, wear and contamination can affect how well the turbo functions. Determining whether it can be serviced or requires replacement depends on the extent of the issue.
In certain situations, a turbo assembly can be serviced, particularly when the problem is related to external components or minor buildup. Addressing these issues early can help restore proper function without replacing the entire unit.
A turbo may be serviceable when you’re dealing with:
- Carbon deposits restricting internal movement
- Oil residue buildup affecting performance
- Worn external seals or fittings causing minor leaks
- Control or actuator-related issues impacting operation
That said, internal turbo components operate at very high speeds and tolerances. If these parts are damaged, repair is often not a reliable long-term solution.
Replacement is usually the better option when:
- Internal rotating components are damaged
- There is noticeable shaft movement or imbalance
- Bearings have deteriorated from wear or contamination
- The housing shows signs of cracking or heat damage
A detailed inspection is the best way to determine the condition of the turbo assembly. Identifying underlying causes—such as oil supply issues or contamination—can also help prevent future failures and ensure the new or serviced unit lasts longer.
The gases spin the turbine, which drives the compressor to increase intake air pressure.
The turbocharger works with the intake and exhaust systems to manage airflow through the engine.
A worn turbo can lead to improper air delivery and may affect engine operation.
Proper alignment with oil supply and exhaust connections is necessary for correct operation.
