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.

    •  Designed for durability, the OEM 4311990 rocker lever is built to withstand the demanding conditions of diesel engines.
  • Compatibility
    •  This part is specifically engineered for Cummins ISX engines, providing a perfect fit and reliable performance.

Maintenance Tips for the Cummins ISX Injector Rocker Lever

  • Inspect for Wear and Tear
    • Regularly inspect the rocker lever for signs of wear, such as cracks or deformation. Replacing worn parts prevents major engine damage.
  • Proper Lubrication
    • Ensure the rocker lever is properly lubricated to reduce friction and prevent premature wear.
  • Timely Replacement
    • Replace the rocker lever when needed to maintain the fuel system’s integrity and avoid injector-related problems.

The Cummins ISX Injector Rocker Lever is vital for your engine's precise fuel injection. Regular maintenance and timely replacement using the OEM 4311990 part will keep your engine running efficiently and reduce the risk of costly repairs. At TamerX Diesel Parts, we provide high-quality parts to ensure your Cummins ISX engine performs at its best.

The injector rocker lever is a critical component in your diesel engine’s valve train, responsible for helping control fuel injection timing and ensuring efficient fuel delivery. When the injector rocker lever begins to fail, it can cause several engine performance issues that, if left unchecked, may lead to more severe engine damage. Recognizing the symptoms of a failing injector rocker lever early on can help prevent costly repairs.

  • Engine Misfires

    •  One of the most noticeable signs of a failing injector rocker lever is engine misfires. This occurs when the lever cannot properly control fuel injection, resulting in incomplete combustion.

  • Loss of Power

    •  A faulty injector rocker lever can cause a drop in engine power, particularly when accelerating or under heavy load. This is due to improper fuel delivery to the cylinders.

  • Rough Idling

    • If the injector rocker lever isn’t functioning correctly, the engine may idle roughly or stall. This is because the fuel injection timing becomes inconsistent, disrupting the engine’s balance.

  • Poor Fuel Efficiency

    • A malfunctioning injector rocker lever can lead to inefficient fuel combustion, resulting in poor fuel economy. You may notice an increase in fuel consumption over time.

  • Excessive Engine Noise

    • A failing injector rocker lever can cause unusual tapping or knocking sounds coming from the engine, particularly during acceleration or at idle, due to improper fuel injection timing.

A failing injector rocker lever can cause engine misfires, loss of power, rough idling, poor fuel efficiency, and increased engine noise. If you notice any of these symptoms, it’s crucial to have your engine inspected and the injector rocker lever repaired or replaced promptly. Addressing these issues early can prevent more extensive engine damage and keep your vehicle running smoothly. Regular maintenance and attention to early signs of failure are key to ensuring the longevity and performance of your engine.
