Q: How to remove, inspect, and install a flywheel or driveplate in DOHC four cylinder engine on 1998 Ford Ranger?
A: On 2011 automatic transmission-equipped models, the driveplate is known as a flexplate by the manufacturer. To begin removal, first take out the transmission, then remove the clutch if equipped, replacing any worn components if the vehicle has high mileage. Mark the flywheel/driveplate to the crankshaft with paint or a center punch for proper reinstallation. To prevent the flywheel/driveplate from turning, install one transmission mounting bolt into the cylinder block and have an assistant hold a prybar against the mounting bolt while loosening the bolts. Remove all bolts except one, leaving it installed halfway, then pull the flywheel/driveplate away from the crankshaft flange, using a mallet if necessary. Support the flywheel/driveplate while removing the last bolt, taking care as it is heavy and has sharp edges. If the rear oil seal shows signs of leakage or the vehicle has high mileage, it is advisable to replace the seal before reinstalling the flywheel/driveplate. For inspection, clean the flywheel/driveplate to remove grease or oil, checking for cracks, rivet grooves, burned areas, and score marks, with light scoring removable using emery cloth. Inspect for cracked and broken ring gear teeth, and check for warpage using a straight-edge, as resurfacing by a professional machine shop may be necessary for severe wear or damage. Clean and inspect the mating surfaces of the flywheel/driveplate and the crankshaft. For installation, if the engine/transmission adapter plate was removed, reinstall it, then place the flywheel/driveplate on the crankshaft ensuring all bolt holes align, and install the proper bolts, tightening them by hand. Torque the mounting bolts in a crisscross pattern and in three stages, with the remainder of the installation being the reverse of removal.
