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 Hino J08E 7.7L DOC (Diesel Oxidation Catalyst) (OEM S1805E069) is an essential component of the exhaust aftertreatment system for 2014–2017 Hino J08E 7.7L engines. Installed near the beginning of the exhaust system, the DOC initiates the emissions treatment process by converting harmful pollutants into less harmful gases before they move through the remaining aftertreatment components. It works alongside the Diesel Particulate Filter (DPF) and Selective Catalytic Reduction (SCR) system to help the engine meet modern diesel emissions standards. 

Although it operates automatically, the DOC is one of the most important components for maintaining an efficient and reliable emissions control system.

Why is the Hino J08E 7.7L DOC important?

  • Reduces harmful exhaust pollutants
    The DOC converts carbon monoxide (CO) and unburned hydrocarbons (HC) into less harmful carbon dioxide and water vapor before they leave the exhaust system.

  • Starts the emissions treatment process
    As the first catalyst in the aftertreatment system, it prepares exhaust gases for the DPF and SCR, allowing those components to operate more effectively.

  • Generates heat for DPF regeneration
    The catalytic reaction inside the DOC increases exhaust temperature, helping the Diesel Particulate Filter remove accumulated soot during regeneration.

  • Supports the efficiency of the aftertreatment system
    Proper DOC operation helps the DPF and SCR function as designed, contributing to cleaner exhaust emissions.

  • Operates continuously without moving parts
    The catalyst performs its job automatically whenever the engine is running, requiring no mechanical movement to treat exhaust gases.

  • Helps maintain emissions compliance
    A properly functioning DOC is critical for meeting emissions regulations and minimizing the risk of aftertreatment-related fault codes or reduced engine operation. 

The Hino J08E 7.7L DOC (OEM S1805E069) serves as the foundation of the engine's emissions control system. By treating harmful exhaust gases before they reach the DPF and SCR, it helps the complete aftertreatment system operate efficiently, supports cleaner emissions, and contributes to the dependable operation of compatible Hino J08E 7.7L engines. 

A Diesel Oxidation Catalyst (DOC) does not have a fixed replacement interval. Instead, it should be replaced when it no longer functions effectively, becomes physically damaged, or reaches the end of its service life. Under normal operating conditions and with proper engine maintenance, a DOC can often last 200,000 to 500,000 miles or more.

Rather than replacing the DOC based on mileage alone, it's important to monitor its condition and address any warning signs as they appear.

Here are the most common indicators that it's time to replace your DOC:

  • Recurring emissions-related fault codes
    • Frequent diagnostic trouble codes related to the aftertreatment system may indicate the DOC is no longer functioning properly.
  • Frequent regeneration cycles
    • If the engine is regenerating more often than normal, the DOC may not be producing enough heat to support efficient regeneration.
  • Excessive exhaust restriction
    • A clogged or contaminated DOC can increase backpressure, affecting engine operation and fuel efficiency.
  • Physical damage
    • Cracked housings, impact damage, or internal catalyst deterioration are clear signs that replacement is necessary.
  • Reduced emissions system efficiency
    • If diagnostic testing confirms the DOC is no longer effectively treating exhaust gases, replacing it is the most reliable solution.
  • Engine derate or reduced-power mode
    • Serious aftertreatment issues involving the DOC can cause the engine to limit output until the problem is corrected.

Replacing a worn or damaged DOC at the appropriate time helps protect other aftertreatment components, maintain proper emissions system operation, and reduce the likelihood of more expensive repairs. Regular engine maintenance and routine inspections are the best ways to maximize the lifespan of your DOC.

Technicians should inspect the exhaust clamps, mounting hardware, sealing gaskets, temperature sensors, DPF, adjoining exhaust pipes, and related aftertreatment components to ensure proper installation and system operation.

Yes. As part of the complete aftertreatment system, the DOC helps reduce exhaust emissions and supports compliance with applicable emissions standards for compatible Hino J08E-powered vehicles.

A properly functioning DOC helps maintain the correct exhaust chemistry and temperature for downstream components, contributing to efficient DPF regeneration and overall emissions system performance.

Using the correct OEM S1805E069 helps ensure proper fitment, compatibility with the original Hino aftertreatment system, factory-designed exhaust flow characteristics, and reliable long-term emissions performance for compatible J08E 7.7L engines.
