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.

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.

Designed for Volvo and Mack engines from 1996 to 2004, this air brake compressor ensures that your air brake system operates safely and efficiently. In this blog, we’ll discuss the key functions of the air brake compressor and offer tips for maintaining it to ensure long-term reliability.

Key Functions of the Volvo Mack Air Brake Compressor:

  • Air Pressure Generation
    •  The air brake compressor generates the necessary air pressure to engage the braking system, ensuring that the brakes respond quickly and effectively.
  • OEM Quality
    •  Manufactured to meet the high standards of Volvo and Mack, OEM 3946077 ensures a precise fit and durable performance for air brake systems in trucks from 1996-2004.
  • Consistent Air Supply
    • This compressor maintains a consistent supply of pressurized air, ensuring the brake system functions smoothly and reducing the risk of brake failure.

Maintenance Tips for Air Brake Compressors:

  • Inspect for Air Leaks
    •  Regularly check the compressor and air lines for leaks, as air pressure loss can lead to reduced brake efficiency and longer stopping distances.
  • Clean or Replace Air Filters
    • Ensure the air filters are clean to prevent dirt and debris from entering the compressor, which could cause damage and reduce performance.
  • Monitor Air Pressure Levels
    • Pay attention to the air pressure gauge on your vehicle. If the pressure is too low or fluctuating, it may indicate an issue with the compressor.
  • Lubricate as Needed
    •  Ensure that the compressor is properly lubricated to reduce wear and tear on moving parts, helping to prolong the life of the component.:

The Volvo Mack Air Brake Compressor (OEM 3946077) is a critical component for ensuring the safe operation of your air brake system. By following regular maintenance practices such as checking for air leaks, cleaning filters, and monitoring air pressure, you can extend the life of your compressor and keep your brakes functioning efficiently. Trust TamerX Diesel Parts to provide high-quality OEM components that keep your air brake system in top condition.

The air brake compressor is a vital component in commercial vehicles, providing the necessary air pressure to operate the braking system. When the air brake compressor fails, it can lead to unsafe driving conditions and costly repairs. Understanding the common causes of air brake compressor failure can help you maintain your braking system and avoid unexpected breakdowns.

Common Causes of Air Brake Compressor Failure:

  • Lack of Lubrication

    •  Air brake compressors rely on proper lubrication to function smoothly. Inadequate oil levels or contaminated oil can lead to increased friction and wear, eventually causing the compressor to fail.

  • Overheating

    • Continuous use or malfunctioning cooling systems can cause the compressor to overheat. Excessive heat can damage internal components, such as seals and valves, leading to reduced efficiency or complete failure.

  • Air Leaks

    •  Leaks in the air system put additional strain on the compressor as it works harder to maintain the necessary pressure. This extra load can cause premature failure of the compressor.

  • Contaminants in the System

    •  Dirt, debris, or moisture can enter the air brake system and cause damage to the compressor. Water in the air system, especially, can corrode components, leading to breakdowns.

  • Normal Wear and Tear

    • Like any mechanical component, air brake compressors experience wear over time. Aging parts such as pistons, rings, or gaskets can degrade, leading to a drop in performance or compressor failure.

  • Faulty Pressure Regulator

    • A malfunctioning pressure regulator can cause the compressor to operate under excessive strain by either over-pressurizing or under-pressurizing the system, which can lead to failure.

Air brake compressor failure can result from factors such as lack of lubrication, overheating, air leaks, and contamination. Regular maintenance, including checking oil levels, inspecting for leaks, and ensuring the system is free of contaminants, is essential for prolonging the life of the compressor. Addressing potential issues early will help maintain the reliability of your braking system and ensure safe operation of your vehicle.

No, it cycles on and off based on air system demand controlled by the governor.

If its valves or fittings are damaged, it may introduce leaks or fail to pressurize the system properly.

With proper maintenance and clean oil, it can last hundreds of thousands of miles.

Use pressure build-up time tests, check for excessive oil in the tanks, and listen for abnormal noises.
