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 Bobcat / Doosan D34 DOC (Diesel Oxidation Catalyst) (OEM 7313995) is a key aftertreatment component designed for 2014–2020 Bobcat and Doosan D34 engines. Installed at the beginning of the exhaust aftertreatment system, the DOC uses a catalytic coating to convert harmful exhaust gases into less harmful compounds before they reach downstream emissions components. This OEM part helps compatible equipment meet Tier 4 and Stage IV emissions requirements.

Unlike a Diesel Particulate Filter (DPF), the DOC does not trap soot. Instead, it chemically treats exhaust gases as they pass through the catalyst, improving the efficiency of the entire emissions system.

What are the functions of the Bobcat / Doosan D34 DOC?

  • Converts harmful exhaust gases
    • The DOC transforms carbon monoxide (CO) and unburned hydrocarbons (HC) into carbon dioxide and water vapor through a catalytic reaction.
  • Begins the emissions treatment process
    • Positioned at the front of the aftertreatment system, it serves as the first stage of exhaust treatment before gases move to downstream emissions components.
  • Generates heat for downstream components
    • The oxidation process creates heat that helps support the regeneration of the Diesel Particulate Filter (DPF), allowing it to remove accumulated soot more effectively.
  • Supports cleaner exhaust emissions
    • By reducing pollutants early in the exhaust stream, the DOC improves the overall efficiency of the emissions control system.
  • Operates continuously during engine operation
    • With no moving parts, the catalyst performs its function automatically whenever exhaust gases pass through it.
  • Helps maintain emissions compliance
    • A properly functioning DOC helps compatible Bobcat and Doosan equipment meet Tier 4 and Stage IV emissions standards while supporting the performance of the complete aftertreatment system.

The Bobcat / Doosan D34 DOC (OEM 7313995) serves as the first stage of the engine's emissions control system. By reducing harmful exhaust gases and preparing the exhaust for downstream components like the DPF and SCR system, it helps the entire aftertreatment system operate efficiently while contributing to cleaner emissions and dependable engine operation.

A Diesel Oxidation Catalyst (DOC) is an important part of your vehicle's emissions system, helping reduce harmful exhaust emissions before they reach the atmosphere. Over time, contamination, excessive soot, or internal damage can reduce the DOC's effectiveness. Recognizing the warning signs early can help prevent more extensive aftertreatment system repairs.

Here are the most common signs that your DOC may be failing:

  • Check engine light
    • An illuminated check engine light accompanied by emissions-related diagnostic trouble codes is often one of the first indicators of a DOC problem.
  • Frequent regeneration cycles
    • If the vehicle is regenerating more often than usual, the DOC may not be generating enough heat to properly support the regeneration process.
  • Loss of engine responsiveness
    • A restricted or damaged DOC can increase exhaust backpressure, causing sluggish acceleration and reduced engine efficiency.
  • Excessive exhaust smoke
    • Changes in exhaust smoke, particularly if combined with other symptoms, may indicate the emissions system is not operating correctly.
  • Higher fuel consumption
    • An inefficient DOC can cause the engine to work harder, resulting in increased fuel usage over time.
  • Engine derate or reduced-power mode
    • Many diesel engines will limit engine output when serious aftertreatment system faults are detected to protect the emissions system.
  • Unusual exhaust odors or excessive heat
    • A damaged or contaminated DOC may produce abnormal exhaust odors or excessive heat around the aftertreatment system.

If you notice any of these symptoms, have the DOC and the rest of the emissions system inspected as soon as possible. Addressing the issue early can help prevent damage to related components, reduce repair costs, and keep your diesel engine operating reliably.

The DOC is engineered for continuous operation under high exhaust temperatures, vibration, heavy workloads, and repeated thermal cycling commonly encountered in construction and industrial equipment.

Technicians should inspect the exhaust clamps, mounting hardware, sealing gaskets, temperature sensors, adjoining exhaust pipes, and surrounding aftertreatment components to ensure a proper installation and leak-free operation.

No. The OEM 7313995 DOC is manufactured without a temperature sensor mounting hole, making it important to confirm the correct part number for the specific machine configuration before installation.

Technicians typically inspect the DOC when diagnosing exhaust restriction, catalyst damage, emissions-related fault codes, abnormal exhaust temperatures, or visible damage to the aftertreatment system.
