Driveplate — removal and installation Ford F150

1. Raise the vehicle and support it securely on jackstands, then refer to Chapter 7A and remove the transmission. If it’s leaking, now would be a very good time to replace the front pump seal/O-ring.

2. Look for factory paint marks that indicate driveplate-to-crankshaft alignment. If they aren’t there, use a center-punch or paint to make alignment marks on the driveplate and crankshaft to ensure correct alignment during reinstallation.

3. Remove the bolts that secure the driveplate to the crankshaft. If the crankshaft turns, use a flywheel holding tool or wedge a screwdriver in the ring gear teeth to jam the drive-plate.

4. Remove the driveplate from the crankshaft.

5. Check for cracked and broken ring gear teeth.

6. Clean and inspect the mating surfaces of the driveplate and the crankshaft. If the crankshaft rear seal is leaking, replace it before reinstalling the driveplate (see Rear main oil seal – replacement).

7. Position the driveplate against the crankshaft, but make sure the crankshaft sensor ring is positioned between the driveplate and the engine. Be sure to align the marks made during removal. Note that some engines have an alignment dowel or staggered bolt holes to ensure correct installation.
