Quick Ship SKU #: DD-GOS-FANHUB-Main Driven Diesel Mechanical Fan Clutch Adapter 03-18 Dodge 5.9L / 6.7L Cummins

The factory electronically controlled fan clutch on the Common Rail Cummins is known to have its issues. If you're ready to convert yours over to a good, reliable mechanical fan clutch, its really not that difficult, you just need the right parts, including this specialty adapter and the right fan clutch, in this case, one from an "OBS" Ford, or a 1994-1997 model year Ford, and you're good to go!

This adapter and the associated parts will deliver the reliable cooling solution you are looking for. Check the list below for the necessary parts combinations. In order to use your existing engine fan blade, you must have the 6-Bolt blade assembly (typically found on 03-08 trucks only). If you have the 4-Bolt blade assembly, you will need to purchase the fan blade, as well.

OPTIONS:

• Fan Clutch Adapter: The adapter is the only necessary part of this conversion outside of the OBS Fan Clutch and your stock fan. That said, when replacing the adapter, it is highly recommended to also replace the bearing while you are in there.
• Fan Clutch Adapter with Bearing: As stated above, its highly recommended to also replace the bearing when installing the new fan clutch adapter. This option includes a bearing you will need to replace with your existing bearing. In many cases, the factory bearing will be seized into the housing, requiring some diligence to replace.
• Fan Clutch Complete Assembly: This is the ideal option, delivering you a complete adapter pre-installed onto a new Cummins Fan Hub Assebly with a pre-installed bearing. See Related Products section below for this option.

• Removing the Electronic Fan Clutch from your truck WILL leave an error code in the computer. In our experience, this does not typically trigger the "Check Engine Light", but the soft code will always be present. At this time, we are not aware of any way to disable this code. On some rare occasions on the 6.7 Cummins we have had issues where the A/C will blow warmer due to air flow at idle. 
• CUMMINS CONVERSION (COMMON RAIL) CUSTOMERS - Using the stock Dodge Common Rail electronic engine fan in a Cummins conversion project can be a real hassle. Many conversion owners have found that keeping the engine cool with the Dodge electronic fan can be quite challenging. This adapter hub will allow the use of a standard mechanical fan clutch (Ford) and fan on your Common Rail Cummins engine. This eliminates messing around with electronic controls and provides a much more reliable "mechanical" solution to cooling your conversion engine.
• Driven Diesel recommends using the Ford "OBS" Fan Clutch and the Ford 6.0L Fan (23.25" Diameter). While it may be possible to fit the larger Dodge fan (26" Diameter) into some conversions, we CANNOT provide you with information about doing so. It is YOUR RESPONSIBILITY to measure your clearances and order the fan that will best fit your application.
