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 John Deere 6068 DOC (OEM DZ102277) is a key aftertreatment component designed for 2021–2025 John Deere 6068 engines. As a Diesel Oxidation Catalyst (DOC), it serves as the first stage of the emissions control system, helping reduce harmful exhaust gases before they reach downstream components such as the DPF and SCR. 

Unlike a filter that traps soot, the DOC uses a catalyst to trigger chemical reactions that clean the exhaust as it passes through.

What Does the John Deere DZ102277 DOC Do?

  • Converts harmful exhaust gases
    • The DOC changes carbon monoxide (CO) and unburned hydrocarbons (HC) into less harmful substances, including carbon dioxide and water vapor.
  • Begins the emissions treatment process
    • Positioned at the front of the aftertreatment system, it prepares exhaust gases before they move to the DPF and SCR.
  • Generates heat for downstream components
    • The catalytic reaction inside the DOC produces heat, helping the DPF reach the temperatures needed for effective regeneration.
  • Supports cleaner exhaust emissions
    • By reducing pollutants early in the exhaust stream, the DOC improves the overall efficiency of the emissions system.
  • Works continuously during engine operation
    • With no moving parts, it performs its function automatically whenever exhaust gases flow through the catalyst.
  • Helps maintain emissions compliance
    • The DOC is an essential part of the aftertreatment system that helps the engine meet modern environmental regulations.

Think of the John Deere DZ102277 DOC as the first line of defense against exhaust pollutants. By treating harmful gases before they reach the rest of the aftertreatment system, it helps the DPF and SCR operate more effectively while supporting cleaner emissions and reliable engine operation.

While your vehicle may still be drivable with a broken Diesel Oxidation Catalyst (DOC), it's not advisable to continue driving for an extended period. A damaged DOC can interfere with the operation of your emissions system and may eventually affect engine efficiency and other aftertreatment components.

The severity of the problem depends on whether the DOC is physically damaged, internally clogged, or no longer functioning as intended. Ignoring the issue can lead to more costly repairs over time.

Here’s what can happen if you continue driving with a broken DOC:

  • Restricted exhaust flow
    • If the DOC is clogged or internally damaged, exhaust gases may not flow efficiently, creating backpressure that places additional strain on the engine.
  • Reduced engine responsiveness
    • Restricted exhaust flow can make the vehicle feel sluggish, especially during acceleration or when operating under heavy loads.
  • Check engine light and emissions fault codes
    • A damaged DOC can trigger diagnostic trouble codes and warning lights related to the emissions system.
  • Higher fuel consumption
    • The engine may consume more fuel as it attempts to compensate for inefficient exhaust flow and changing operating conditions.
  • Increased stress on other aftertreatment components
    • A faulty DOC can affect the operation of the DPF, SCR system, and emissions sensors, potentially leading to additional repairs.
  • Possible engine derate
    • Many modern diesel engines will reduce engine output or limit vehicle speed when emissions-related faults remain unresolved.

Driving a short distance to a repair facility is generally acceptable, but delaying repairs can increase the risk of additional emissions system damage and higher repair costs. Having the DOC inspected and repaired promptly is the best way to protect your engine and maintain reliable vehicle operation.

The DOC is specifically designed to reduce carbon monoxide (CO) and hydrocarbon (HC) emissions while helping prepare exhaust gases for subsequent emissions treatment stages.

The DOC is commonly installed on John Deere industrial engines powering generators, construction equipment, forestry machines, and other heavy-duty applications equipped with compatible 6068 engines.

By increasing exhaust gas temperatures through catalytic oxidation, the DOC helps create the operating conditions required for efficient performance of downstream SCR components.

The assembly features a heavy-duty stainless-steel housing surrounding a ceramic catalyst substrate engineered to withstand high exhaust temperatures and continuous commercial operation.
