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 John Deere 4045 Turbo Assembly (OEM RM100402) is a key engine component designed for 2011–2022 John Deere 4045 engines. It uses energy from the engine's exhaust gases to compress incoming air, supplying the engine with the airflow needed for efficient combustion and dependable operation. This remanufactured 24-volt turbocharger is engineered to meet OEM performance standards for compatible John Deere applications.
Rather than allowing exhaust energy to go unused, the turbo assembly recovers that energy and uses it to improve airflow throughout the engine, making it an essential part of the intake and exhaust system.
What Does the John Deere RM100402 Turbo Assembly Do?
- Converts exhaust energy into compressed air
- The turbo captures exhaust gas energy to spin an internal turbine, which compresses fresh air entering the engine.
- Supplies oxygen for efficient combustion
- By increasing the amount of air delivered to the cylinders, it helps create the proper conditions for clean and consistent fuel combustion.
- Adjusts to changing engine demands
- The turbo responds automatically to variations in engine speed and workload, providing the airflow required for different operating conditions.
- Supports the intake and exhaust systems
- It serves as the connection between the intake and exhaust sides of the engine, helping maintain balanced airflow.
- Promotes smooth engine operation
- Consistent airflow contributes to stable combustion, reliable engine response, and efficient day-to-day operation.
- Works with the engine management system
- The turbo operates alongside the engine control module (ECM) to help regulate airflow based on real-time engine conditions.
The John Deere RM100402 Turbo Assembly functions as the engine's airflow management center. By transforming exhaust energy into compressed intake air, it helps maintain efficient combustion, supports the engine's intake and exhaust systems, and contributes to reliable operation across a wide range of applications.
A turbo assembly is designed to provide a steady supply of compressed air to your engine, but as it begins to wear, you'll often notice changes in how your vehicle performs. Recognizing the warning signs early can help you avoid more extensive engine damage and costly repairs.
Because the turbocharger operates under extreme heat and high rotational speeds, even minor problems can quickly become major failures if left unattended.
Here are the most common signs of a bad turbo assembly:
- Noticeable loss of acceleration
- If your vehicle struggles to accelerate or feels less responsive than usual, the turbo may not be producing the boost pressure the engine requires.
- Excessive exhaust smoke
- Blue smoke may indicate oil leaking through worn turbo seals, while black smoke can suggest the engine isn't receiving enough air for efficient combustion.
- Whining, grinding, or rattling noises
- Unusual sounds coming from the turbocharger often indicate worn bearings, damaged compressor blades, or internal component failure.
- Higher-than-normal oil consumption
- A damaged turbo can allow engine oil to leak into the intake or exhaust system, causing oil levels to decrease more quickly.
- Check engine light
- Faulty boost pressure or airflow readings can trigger diagnostic trouble codes and illuminate the check engine light.
- Oil leaks around the turbocharger
- Oil residue around the turbo housing, oil lines, or charge air piping may indicate worn seals or internal damage.
- Inconsistent boost pressure
- Fluctuating turbo boost can cause hesitation, uneven acceleration, and inconsistent engine operation.
- Reduced fuel economy
- When the turbo isn't supplying enough compressed air, the engine may burn more fuel to maintain normal operation.
If you notice one or more of these symptoms, it's important to inspect the turbo assembly as soon as possible. Early diagnosis can help prevent complete turbo failure, protect your engine from secondary damage, and reduce overall repair costs.
Common indicators include excessive exhaust smoke, abnormal turbocharger noise, oil leakage around the turbocharger, reduced engine response, or turbocharger-related diagnostic fault codes.
The assembly includes the compressor housing, turbine housing, center housing rotating assembly (CHRA), bearings, seals, shaft, and integrated electronic actuator, forming a complete replacement turbocharger.
The turbocharger is built with heavy-duty cast housings, precision-balanced rotating components, heat-resistant materials, and durable bearings designed for continuous commercial and industrial service.
Each RM100402 undergoes a comprehensive remanufacturing process, including replacement of wear components, inspection of critical parts, machining where required, and rigorous testing to verify it meets original performance standards.
