As is the case for the majority of the diesel products sold on Tamerx, 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 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 Turbo Actuator 2025-2027: OEM 6473311 is an electronically controlled component that manages the operation of the turbocharger on compatible Cummins B6.7 diesel engines. Its primary function is to control the position of the turbocharger’s variable geometry mechanism according to changing engine operating conditions.
By making precise adjustments, the actuator helps the turbocharger regulate airflow and exhaust flow across different engine speeds and loads.
What Does the Turbo Actuator Do?
- Controls turbocharger geometry
- The actuator adjusts the turbo mechanism to regulate how exhaust gases interact with the turbine.
- Responds to engine conditions
- It changes position based on commands from the engine control system as speed, load, and operating demands vary.
- Manages intake airflow
- Proper turbo control helps maintain the amount of compressed air required by the engine.
- Supports efficient combustion
- Accurate airflow management helps maintain suitable air-to-fuel conditions inside the cylinders.
- Assists with exhaust management
- Turbo positioning can influence exhaust flow and temperature, which are important for modern diesel aftertreatment systems.
- Supports exhaust braking functions
- On applications using the variable geometry turbo for exhaust braking, actuator movement helps create the necessary exhaust restriction.
Precise Control of the Turbocharger
The Cummins B6.7 Turbo Actuator (OEM 6473311) is important because the variable geometry turbo depends on accurate actuator movement. If the actuator becomes faulty or cannot properly control the turbo mechanism, symptoms may include slow acceleration, inconsistent turbo response, abnormal exhaust behavior, warning lights, or turbo-related fault codes.
Keeping electrical connections secure and addressing turbo or actuator fault codes promptly can help prevent additional stress on the turbocharger system.
A vehicle may still run with a faulty Turbo Actuator, but continuing to drive is generally not recommended. The actuator controls the turbocharger's variable geometry or wastegate position, depending on the system. When it fails, the turbocharger may no longer respond correctly to engine operating conditions.
Driving with a faulty Turbo Actuator can lead to several problems:
- Poor acceleration
- The engine may feel sluggish because the turbocharger is not being controlled correctly.
- Check engine light
- The engine control module may detect incorrect actuator position or movement and store related fault codes.
- Engine derate
- Some diesel engines may limit vehicle operation when a serious turbo control fault is detected.
- Irregular turbo operation
- A stuck or slow-moving actuator can prevent the turbo vanes or wastegate from reaching the commanded position.
- Excessive exhaust smoke
- Incorrect airflow can affect combustion and contribute to unusual black or gray exhaust smoke.
- Higher exhaust temperatures
- Improper turbo control can contribute to abnormal exhaust temperature conditions.
- Additional turbocharger damage
- Continuing to operate the engine with a binding actuator or variable-geometry mechanism can place unnecessary stress on turbo components.
- Unexpected drivability problems
- The condition can worsen and lead to hesitation, inconsistent acceleration, or more severe operating restrictions.
If the actuator is malfunctioning, have the actuator, wiring, connectors, turbo mechanism, and related sensors diagnosed before replacing parts. A turbo actuator fault code does not always mean the actuator itself has failed; electrical problems, carbon buildup, or a sticking turbo mechanism can produce similar symptoms.
Yes, damaged wiring, loose terminals, corrosion, or poor electrical connections can interfere with communication and operation of the 6473311.
Yes, prolonged exposure to abnormal heat around the turbocharger can place thermal stress on the electronics and mechanical components of the 6473311.
No, forcing the 6473311 manually can damage its internal gears, motor, or position-sensing components.
Correct alignment allows the 6473311 to engage the turbocharger mechanism properly without binding or placing unnecessary stress on its internal components.
