Killer Dowel Pin
The last thing we had DDP help us out with while we were under the hood of the truck is installing its Killer Dowel Pin mod. In the 12V Cummins engine there is a small dowel pin behind the front cover that has a tendency to work itself loose under the miles and extreme vibration these motors are subjected to. Problem is, if or when this dowel pin works itself completely loose and falls out, it will find itself falling onto one of the front gears of the engine. The gear continues to turn, the pin will bind up between it and the front cover, blowing the side of the cover out. And that's something that can be very expensive and time-consuming to fix. So as a precautionary measure, DDP installed its Killer Dowel Pin, which put a small metal tab in front of the factory pin. This tab will block the pin from being able to come completely out, preventing future issues.
