Swap out the damaged or cracked flex plate in your 2011-2016 Ford 6.7L Powerstroke. Cracks or failures can occur in a flex plate from an out of balance engine or torque converter as well as from bolts that were not properly torqued or in the correct sequence. The teeth on the ring gear can also wear or break off due to a bad starter, failure to use starter shims (where required), or engaging the starter while the engine is running. Noises while starting the engine can also be an indication of either a starter failure or broken teeth on your flex plate. Over time flex plates can become cracked causing it to vibrate. Symptoms of a cracked flex plate can include clunking sounds or a grinding noise while the engine is running. The flex plate is a metal disc used to connect the engine to the torque converter. They are used on vehicles with an automatic transmission, as opposed to a flywheel that is normally used with a manual transmission. Flex plates are typically lighter and thinner than flywheels. A flex plate consists of two parts, the flex-plate and ring gear. Available in OE-replacement style steel or upgraded billet units that are SFI 29.1 certified.
