2009 Ford F-350 Super Duty Pressure Plate Parts Q&A

• Q: How to service and repair the clutch disc and pressure plate for 5.4L, 6.8L, and 6.4L engines on 2009 Ford F-350 Super Duty?

  A: The first step for clutch disc and pressure plate servicing and repair of 5.4L, 6.8L and 6.4L engines starts with removing the transmission. Index the clutch pressure plate and flywheel when they will be put back during reinstallation. Begin the service by removing bolts from the clutch pressure plate along with the pressure plate itself and the clutch disc. The transmission input shaft pilot bearing needs replacement if you find any misalignment, looseness, scoring, discoloration, wear, broken rollers or seal damage when examining the bearing. The clutch disc friction surface should be smoothened with emery cloth and the disc should be tested for wear using needed replacement criteria including oil saturation, worn rivets, broken springs, and spline wear. The clutch pressure plate friction surface must be cleaned while the levers need inspection for wear and the friction surface for scoring, burning, distortion, or warping. If any conditions exist you must replace these components. The flywheel clutch surface should be cleaned while the technician checks it for cracks, heat checks, glazing, scoring or grooves. Minor damage can be fixed with coarse emery cloth or 400 grit sandpaper. Seek broken or worn teeth on the ring gear. Before installation you should apply grease to the pilot bearing of the transmission input shaft when necessary. To reset the original clutch pressure plate wear indicator you should press down your fingers before turning the adjusting ring counterclockwise and letting go while using your fingers to maintain the ring in its reset position. Use the clutch alignment tool to position the disc correctly into the pilot bearing of the assembly process by understanding that 5.4L/6.8L engines require a 1-1/4 in input shaft and 6.4L engines require a 1-3/8 in input shaft with a 0.98 in pilot bearing inner diameter. You should align the index marks when replacing the original clutch pressure plate after which you should position it on the dowels which equal two for diesel engines and three for gasoline engines. Use the clutch alignment tool to properly position the clutch disc and pressure plate before installing the clutch pressure plate bolts according to a star pattern sequence where torque values amount to 45 Nm (33 lb-ft) for 5.4L and 6.8L engines and 28 Nm (21 lb-ft) for the 6.4L engine. Put the clutch alignment tool off the components afterward you set the transmission in place for examining standard operation.
