SHIPPING POLICY

Drive On Diesel 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 Drive On Diesel 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.

Drive On Diesel 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 Drive On Diesel, 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). Drive On Diesel 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 Drive On Diesel, 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. Drive On Diesel 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 Drive On Diesel core charge presented to you online today with your item is representative of the most common core charge.

The Cummins B6.7 Turbo Assembly (OEM 6395642) is a sophisticated airflow component designed to help the engine efficiently manage incoming air and outgoing exhaust gases. Built for 2022–2024 Cummins B6.7 applications, this turbo assembly uses energy from the exhaust stream to support the engine's air intake process. 

Instead of letting exhaust gases leave the system unused, the turbo assembly captures that energy and redirects it to improve airflow throughout the engine. This makes it one of the most important components connecting the intake, combustion, and exhaust systems.

What Does the Cummins 6395642 Turbo Assembly Do?

  • Recycles exhaust energy
    • The turbo harnesses the force of exhaust gases to spin an internal turbine, transforming wasted energy into useful airflow.
  • Compresses incoming air
    • By increasing the density of the air entering the engine, the turbo helps provide the oxygen needed for efficient combustion.
  • Responds to changing engine demands
    • The assembly continuously adjusts airflow levels based on engine speed, load, and operating conditions.
  • Supports emissions-related systems
    • Proper airflow is essential for systems such as EGR, DOC, DPF, and SCR to function as intended.
  • Coordinates intake and exhaust flow
    • The turbo acts as a bridge between the two systems, helping maintain balanced engine operation.
  • Promotes reliable day-to-day operation
    • Consistent airflow contributes to smoother engine response and stable performance across a variety of working environments.

In Simple Terms

Think of the Cummins 6395642 Turbo Assembly as the engine's air circulation specialist. It captures energy from the exhaust, uses it to move and compress fresh air, and helps create the conditions needed for efficient combustion, emissions control, and dependable engine operation. 

Your turbo assembly is one of the hardest-working components in a diesel engine. Its primary job is to compress incoming air and deliver it to the engine, helping maintain efficient combustion and overall engine operation. Because it operates under extreme temperatures and high rotational speeds, proper maintenance is essential for long-term reliability.

Understanding how the turbo assembly functions can help you recognize potential issues before they become major repairs.

Here are a few important things to know about your turbo assembly:

  • It relies on clean engine oil
    • The turbo's internal bearings depend on a constant supply of clean oil for lubrication and cooling. Poor oil quality or missed oil changes can significantly shorten its lifespan.
  • It operates at extremely high speeds
    • Turbochargers can spin at well over 100,000 RPM, making them highly sensitive to contamination, lubrication issues, and excessive heat.
  • Airflow is critical to its performance
    • Restrictions in the air intake system or charge air cooler can force the turbo to work harder than necessary and contribute to premature wear.
  • Heat management matters
    • Allowing the engine to warm up before heavy use and cool down before shutdown can help reduce thermal stress on the turbocharger.
  • Small problems can become expensive repairs
    • Symptoms such as unusual noises, oil leaks, excessive exhaust smoke, or reduced engine response should be investigated promptly to prevent further damage.
  • Regular inspections can extend service life
    • Checking air filters, oil condition, hoses, clamps, and related components can help identify issues before they affect turbo operation.

A properly maintained turbo assembly can provide many years of reliable service. Staying proactive with maintenance and addressing warning signs early are the best ways to maximize its lifespan and protect your engine.

Signs may include unusual turbo noises, excessive exhaust smoke, oil residue around the turbo housing, or airflow-related diagnostic fault codes.
