Bolt On Fuel Pump Drive Hub for Flat Face Gear fits Cummins 5.9L

Bolt on fuel pump drive hub to drive Waterman or similar pump off the auxiliary/power steering pump gear. Fits 1994 to 2002 Cummins 5.9L engines. 3/8″ hex. Used on flat face gears only. Two of the pictures show the gear that this drive is designed for. Gear not included. Gears have a different shaft diameter so the gears can’t be swapped on the pumps. If your gear has a recess in the face see our other drive. Normally we cut the shaft of the pump off leaving a small amount sticking out to use as a pilot to locate this drive hub.  There are two different drives available. Our timing covers are designed to fit factory gear housings. Some of the aftermarket gear housing being sold as factory replacements have the auxiliary pump location shifted slightly which doesn’t matter until you try and install a Waterman style fuel pump using any drive hub adapter like this. This will work with factory gear housings, but be aware if you are using an aftermarket one it may not line up. If you have any additional questions, please call Keating Machine for more details.
