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.

The Paccar MX11 Turbo Assembly (OEM 5495957) is essential for maintaining optimal airflow and ensuring that the engine runs efficiently. A properly functioning turbocharger compresses the incoming air, allowing for better combustion and improved fuel economy. In this blog, we’ll focus on the role of this turbo assembly and offer maintenance tips to keep it performing at its best.

Key Functions of the Paccar MX11 Turbo Assembly:

  • Air Compression for Efficient Combustion
    • The turbocharger compresses air entering the engine’s combustion chamber, allowing for more efficient fuel combustion and increasing engine output.
  • OEM Quality
    • As an original equipment manufacturer (OEM) part (5495957), this turbo assembly is designed to meet the highest quality standards, ensuring a precise fit and reliable performance for Paccar MX11 engines.
  • Fuel Economy Improvement
    • By increasing the air-to-fuel ratio, the turbo helps the engine run more efficiently, reducing fuel consumption and emissions.

    • Whistling, grinding, or other abnormal noises may indicate problems with the turbo. Address these issues promptly to avoid further damage.
  • Allow Cool-Down Time
    • After long drives, let the engine idle for a few minutes before turning it off. This helps the turbo cool down gradually, preventing heat damage.

The Paccar MX11 Turbo Assembly (OEM 5495957) plays a crucial role in boosting engine efficiency by ensuring proper airflow and fuel combustion. Regular maintenance, such as checking for leaks, cleaning air filters, and allowing proper cool-down time, can prolong the life of your turbo and keep your engine performing optimally. For high-quality OEM parts, trust TamerX Diesel Parts to keep your Paccar engine running smoothly and efficiently.

A turbo assembly is designed to boost your engine’s power and efficiency by forcing additional air into the combustion chamber. However, like any mechanical component, turbo assemblies can fail over time. Understanding what causes turbo assembly failure can help you take preventive measures and maintain the performance of your diesel engine.

Common Causes of Turbo Assembly Failure

  • Oil Contamination

    • One of the leading causes of turbo failure is contaminated oil. Dirt, debris, or sludge in the oil can cause excessive wear on the turbo's internal components, leading to premature failure.

  • Lack of Lubrication

    • Turbos rely on proper lubrication to function smoothly. Insufficient oil supply can cause friction and overheating, which may damage the bearings and other critical parts of the turbo.

  • Excessive Heat

    • Continuous exposure to high exhaust gas temperatures can lead to overheating of the turbo assembly. This may cause warping, cracking, or other forms of damage to the internal components.

  • Foreign Object Damage

    •  Small particles, such as dust or debris, entering the turbo can damage the compressor blades, reducing the efficiency of the turbo and eventually causing it to fail.

  • Overboosting

    • If the turbo is forced to produce more boost pressure than it was designed for, it can cause strain on the turbo’s components, leading to cracks or complete failure.

  • Poor Maintenance

    • Neglecting regular maintenance, such as oil changes and filter replacements, can accelerate turbo wear and increase the risk of failure.

Turbo assembly failure can result from several factors, including oil contamination, insufficient lubrication, excessive heat, and foreign object damage. Regular maintenance, using high-quality oil, and monitoring your engine’s boost pressure are key steps to extending the life of your turbo. If you notice signs of a failing turbo, it’s important to address the issue promptly to avoid more costly engine repairs.

Yes, turbocharger issues can disrupt exhaust flow and interfere with EGR and aftertreatment system function.

Clean engine oil should be added to the oil feed port to lubricate the bearings before first engine start.

Possible causes include leaks at intake or exhaust joints, incorrect actuator calibration, or loose charge air connections.

Yes, extended idling can limit oil flow and cooling, which may accelerate internal wear.
