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.

Proper maintenance of this turbo assembly is essential for extending engine life and preventing costly repairs.

Key Functions of the Caterpillar 3406B Turbo Assembly

  • Boosts Airflow
    • The turbocharger increases the amount of air that enters the engine, improving combustion efficiency and power output.
  • Improves Fuel Efficiency
    • By enhancing combustion, the turbo assembly allows the engine to burn fuel more efficiently, reducing fuel consumption.
  • Reduces Emissions
    •  Proper air-fuel mixture from the turbo assembly leads to cleaner combustion, lowering harmful emissions.
  • Durable Design
    • The OEM 0R6957 turbo is built to handle high temperatures and pressures, providing long-lasting performance.

Maintenance Tips for the Caterpillar 3406B Turbo Assembly

  • Regular Inspections
    •  Check the turbo assembly for signs of wear, such as oil leaks or damage to the turbine blades, which could affect performance.
  • Clean Air Filters
    •  Ensure that the air filters are clean and functioning properly to prevent debris from entering the turbo and causing damage.
  • Monitor Oil Levels
    • Turbos rely on a constant supply of clean oil for lubrication. Regularly check oil levels and change the oil as needed to avoid overheating and excessive wear.
  • Replace When Necessary
    •  If you experience a loss of power, unusual noises, or excessive smoke from the exhaust, it may be time to replace the turbo assembly with OEM 0R6957.

The Caterpillar 3406B Turbo Assembly (OEM 0R6957) is essential for maintaining the efficiency and reliability of your engine. By ensuring regular maintenance and timely replacement, you can optimize fuel efficiency, reduce emissions, and extend the life of your engine. TamerX Diesel Parts offers high-quality turbo assemblies and other critical components to keep your Caterpillar 3406B engine running at its best.

A turbo assembly is designed to boost engine performance by increasing the amount of air entering the combustion chamber, allowing your engine to produce more power. When the turbo assembly begins to fail, it can lead to noticeable performance issues and even long-term damage to your engine if not addressed promptly. Understanding the symptoms of a failing turbo assembly can help you take early action and prevent costly repairs.

Common Symptoms of a Failing Turbo Assembly

If your turbo assembly is starting to fail, here are some common symptoms to watch out for:

  • Loss of Power
    •  One of the first signs of turbo failure is a noticeable loss of engine power, especially during acceleration. Your vehicle may struggle to gain speed as it normally would.
  • Excessive Exhaust Smoke
    • A failing turbo can cause oil to leak into the exhaust system, producing thick, dark smoke from the exhaust pipe.
  • Whining or Whistling Noise: A high-pitched whining or whistling sound, particularly when accelerating, can indicate a problem with the turbo, such as damaged or worn components.
  • Check Engine Light
    • The engine control unit (ECU) may detect issues with the turbo and trigger the check engine light to warn of a potential malfunction.
  • Poor Fuel Efficiency: As the turbo struggles to function properly, it can lead to decreased fuel efficiency, as the engine has to work harder to produce the same level of power.
  • Oil Leaks
    • Leaks around the turbocharger or in the intercooler can indicate a failing turbo, often leading to oil loss and potential engine damage.
  • Engine Overheating
    •  A malfunctioning turbo can cause your engine to overheat, as it is no longer able to effectively manage the increased airflow and combustion pressure.

A failing turbo assembly can lead to reduced engine performance, excessive exhaust smoke, and increased fuel consumption. Recognizing the early warning signs—such as loss of power, strange noises, or oil leaks—can help you address the issue before it leads to more serious engine damage. Regular maintenance and careful driving habits will help extend the life of your turbo assembly and keep your vehicle running at peak performance.

Yes, overfueling or prolonged high-load operation without cooling time can lead to heat stress on turbo components.

Unusual whistling, scraping, or grinding sounds can point to foreign object damage, alignment issues, or bearing wear.

Poor oil quality, dirty intake air, lack of cooldown time, and overfueling are key contributors to turbo wear.

Not always—air leaks at charge pipes, loose clamps, or cracked hoses can also create similar sounds.
