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.
"This Product Doesn't Have a Core"
Installed on Detroit DD8 engines produced between 2017 and 2021, OEM A9360781645 is a driving flange engineered to provide a secure connection between rotating components within the engine or accessory drive system. This component is manufactured to OEM specifications to ensure accurate fitment and compatibility with factory assemblies. Constructed from durable materials, it is built to handle the operating stresses and conditions common in modern diesel applications. The driving flange supports consistent torque transfer to help maintain stable system operation. It is a dependable option for fleet maintenance and targeted repair needs requiring reliable mechanical connection integrity.

The Detroit DD8 Driving Flange 2017–2021: OEM DDE A9360781645 is important because it serves as a critical mechanical link within the engine’s rotating assembly. This component helps transfer rotational force between connected drivetrain or accessory components, ensuring smooth and consistent power transmission.
In Detroit DD8 engines, the driving flange is typically mounted at a connection point where torque must be reliably transferred without slippage or misalignment. Because it operates under continuous rotational load, it must be manufactured to precise tolerances to maintain balance and alignment. Even minor wear or distortion can affect connected components and lead to vibration or premature part failure.
OEM DDE A9360781645 is engineered specifically for 2017–2021 Detroit DD8 applications, ensuring proper fitment and compatibility with surrounding assemblies. Its correct installation and condition are essential for maintaining mechanical integrity within the system.
Key reasons the Detroit DD8 Driving Flange is important include:
- Transfers rotational force between connected components
- Maintains proper alignment within the rotating assembly
- Supports smooth and balanced engine operation
- Reduces the risk of vibration-related wear
For fleets and operators, maintaining this component helps protect drivetrain reliability and prevent unexpected mechanical downtime. Though it may appear simple, the driving flange plays a vital role in keeping the engine’s rotational systems operating correctly and efficiently.
The main cause of driving flange failure is excessive vibration and misalignment, which leads to fatigue cracking and eventual structural failure. A driving flange is designed to transmit torque between connected components, and when alignment is compromised or loads exceed design limits, stress concentrates at bolt holes and mounting surfaces.
Improper installation is one of the most common contributors. Uneven torque, incorrect bolt patterns, or failure to follow manufacturer specifications can create imbalance and uneven load distribution. Over time, this causes the flange to loosen, crack, or deform under rotational stress.
Other common factors that accelerate driving flange failure include:
- Shaft misalignment between connected components
- Excessive torsional shock or sudden load changes
- Worn or damaged bearings creating imbalance
- Loose or improperly torqued mounting hardware
- Corrosion weakening the flange material
- Overloading beyond rated torque capacity
In many cases, the flange itself is not the root cause. Underlying drivetrain issues such as worn bearings, improper shaft alignment, or vibration from other components often lead to premature flange failure. Regular inspection, proper torque procedures, and correcting alignment issues are essential to preventing driving flange damage and maintaining reliable torque transfer.
Yes, professional installation is recommended to ensure correct fitment and integration with the engine drive system.
It’s the factory driving flange that couples the turbocharger or accessory drive component to the DD8 engine’s drive system.
It transfers rotational motion from the engine to a driven assembly in the correct orientation.
Yes, it is an OEM-specified flange intended for direct replacement on compatible DD8 applications.
