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 Cummins ISX15 and X15 engines are known for their durability and power in heavy-duty trucks, and a key component in their performance is the rocker arm. The rocker arm controls the movement of the engine’s valves, allowing the intake of air and exhaust of gases. The Cummins ISX15, X15 Rocker Arm (OEM 4393087) plays a vital role in ensuring smooth engine operation. Proper maintenance of this part can significantly impact the engine's longevity and reliability.

Function of the Cummins ISX15, X15 Rocker Arm

  • Controls Valve Movement
    • The rocker arm transmits motion from the camshaft to the valves, ensuring proper air intake and exhaust gas release during the combustion cycle.
  • Precision and Durability
    • OEM 4393087 is designed to match Cummins’ high standards, ensuring durability and precise control over valve timing and movement.
  • Reduces Wear on Valve Components
    •  A properly functioning rocker arm reduces stress on the valves and other engine components, contributing to overall engine health.
  • Critical for Proper Compression
    • The rocker arm ensures that the engine's valves open and close at the right time, maintaining optimal compression and engine efficiency.
  • Made for Heavy-Duty Use
    •  Built to withstand the rigors of daily use in commercial and industrial vehicles, the OEM 4393087 is perfect for engines that face heavy loads and long distances.

Maintenance Tips for the Cummins Rocker Arm

  • Regular Inspections
    • Check for wear, cracks, or damage on the rocker arm during routine maintenance. Replacing worn parts early can prevent larger engine issues.
  • Lubrication
    •  Ensure that the rocker arm is adequately lubricated to prevent friction, which can cause premature wear and failure.
  • Listen for Unusual Noises
    • A faulty rocker arm may cause tapping or clicking sounds in the engine. If you hear these noises, inspect the rocker arm for issues.
  • Valve Adjustment
    •  Ensure proper valve adjustment according to Cummins specifications. Incorrect adjustment can place extra strain on the rocker arm and valves.
  • Use OEM Parts

The Cummins ISX15, X15 Rocker Arm (OEM 4393087) is a crucial component in ensuring your engine's valves function correctly, supporting overall performance and longevity. Regular maintenance, including inspections and timely replacements, will keep your engine running efficiently and reliably. For top-quality OEM parts and expert advice, trust TamerX Diesel Parts to keep your vehicle performing at its best.

The rocker arm plays a critical role in the engine's valvetrain, transferring motion from the camshaft to the valves, allowing the engine to function smoothly. When a rocker arm goes bad, it can cause significant issues that affect the performance and longevity of your engine. While it may be tempting to keep driving with a bad rocker arm, it’s important to understand the potential risks.

  • Engine Misfires

    •  A bad rocker arm can lead to engine misfires, which can cause your engine to run rough or even stall. This happens because the valve isn’t opening properly, affecting the fuel and air mixture.

  • Loss of Power

    •  If the rocker arm can’t efficiently transfer motion to the valves, your engine will lose power. You may notice sluggish acceleration or difficulty driving under load.

  • Excessive Engine Noise

    •  A failing rocker arm can create a distinct ticking or tapping noise coming from the engine. This is often a sign that the arm is not functioning properly.

  • Increased Wear on Engine Components

    •  Continuing to drive with a bad rocker arm can put extra strain on other engine parts, such as the camshaft and valves, leading to more extensive damage over time.

  • Potential Engine Damage

    • If the rocker arm breaks or becomes dislodged, it could cause severe internal damage to the engine, leading to costly repairs or even engine replacement.

Driving with a bad rocker arm is not advisable, as it can lead to engine misfires, power loss, and potential damage to other engine components. If you suspect an issue with your rocker arm, it’s important to have it inspected and repaired promptly. Addressing the problem early can help prevent major engine damage and ensure your vehicle continues to run efficiently. Regular maintenance and timely repairs are key to avoiding costly issues.
