Q: How to remove, inspect, and install a flywheel or driveplate in DOHC four cylinder engine on 2000-2011 Ford Ranger?
A: On 2011 automatic transmission-equipped models, the driveplate is known as a flexplate by the manufacturer. To remove it, first take out the transmission and the clutch if equipped. If any clutch components show wear or the vehicle has high mileage, replacement is recommended. 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 it while removing the last bolt and carefully take it out, noting that it is heavy and has sharp edges, so gloves and caution are advised. If the rear oil seal shows leakage or the vehicle has high mileage, replacing the seal is highly recommended before reinstalling the flywheel/driveplate. For inspection, clean the flywheel/driveplate to remove grease or oil and check for cracks, rivet grooves, burned areas, and score marks, with light scoring removable using emery cloth. Check for cracked and broken ring gear teeth and use a straight-edge to check for warpage, as resurfacing by a professional machine shop may be necessary for severe wear or damage, along with clutch replacement if resurfacing occurs. 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.
