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.


Built to meet the original design standards of the Komatsu 4D95 engine, this set of six OEM 6275-11-3100 fuel injectors ensures proper fuel system function across all cylinders. Each injector is precision-made for a reliable fit and consistent operation within the existing engine setup. Ideal for service intervals or replacing worn components, these injectors install easily without requiring modifications. Their matched construction helps support even combustion and steady engine behavior. Rely on OEM quality to maintain alignment with Komatsu’s factory engineering.

The Komatsu 4D95 engine, commonly found in mid-size construction equipment like loaders, dozers, and excavators, depends on accurate fuel injection for reliable operation. The OEM 6275-11-3100 fuel injector set includes six factory-spec units designed to support consistent fuel delivery and combustion.

Over time, injectors can become worn or clogged, leading to rough idle, decreased efficiency, or trouble starting. Replacing all six at once helps restore balanced operation across all cylinders.

Notable features of the OEM 6275-11-3100 injector set:

  • Precision-Machined Nozzles
    • Designed for fine diesel atomization
  • Heat-Treated Steel Bodies
    • Built for durability in rugged conditions
  • Direct Fit for 4D95 Engines
    • Simplifies installation with no modification
  • Tight Seal Design
    • Prevents leakage and maintains internal pressure
  • Engine-Matched Calibration
    • Ensures consistent injection timing and quantity

Before purchase, confirm your engine model and OEM part number (6275-11-3100) to ensure compatibility with your Komatsu 4D95 application.

This injector set is ideal for restoring factory-grade fuel delivery in equipment used across construction, agriculture, and municipal work.

If your fuel injector has failed, it’s important to take the right steps to prevent further engine damage and restore smooth operation. Ignoring the issue can lead to misfires, rough idling, and even engine failure.

Step-by-Step Action Plan:

  • Confirm the Diagnosis
    • Use an OBD-II scanner to verify injector-related error codes. You can also have a mechanic run a diagnostic to rule out other issues like ignition coil problems or spark plug wear.
  • Stop Driving
    • Driving with a bad injector can cause fuel imbalance and harm other engine components. Avoid operating the vehicle until the problem is resolved.
  • Replace the Injector
    • A faulty injector typically needs to be replaced. Always use a high-quality part that matches your vehicle’s make and model.
  • Check Other Injectors
    • If one injector failed due to debris or clogging, others may be at risk. It’s wise to inspect all of them during the repair.
  • Flush the Fuel System
    • Clean the fuel rail and consider adding a fuel system cleaner to help prevent future buildup.

By acting quickly and thoroughly, you can avoid long-term engine issues and keep your vehicle running dependably.

Symptoms include hard starting, uneven idling, black exhaust smoke, and reduced fuel efficiency.

Yes, no ECM programming is required since these are mechanical injectors.

Yes, a malfunctioning injector can cause uneven fuel delivery, resulting in misfires or rough engine operation.

The injector is lubricated by diesel fuel itself as it flows through the internal components during operation.
