BD Diesel Killer Dowel Pin (KDP) Kit for Cummins

The BD Diesel Killer Dowel Pin (KDP) Kit is a repair kit for Cummins diesel engines. It secures the timing gear housing dowel pin, often called the "killer dowel pin." On these engines, the factory dowel pin behind the timing cover can work loose over time. If it falls into the timing gears, it can cause extensive and costly engine damage.

Key Features:

• Replaces and secures the factory dowel pin with a more permanent solution
• Helps prevent the pin from backing out and dropping into the timing gears
• Helps protect the timing gears and gear housing from damage
• Includes the components needed to complete the repair, such as a replacement pin, a tab and sealing components
• Backed by BD Diesel, a diesel performance brand with roots going back to 1972

Installing a KDP kit is a preventive repair. It addresses a known weak point before it causes a breakdown, so it gives owners of Cummins-powered trucks peace of mind. Select the correct part number for your engine from the options on this page.
