Ford F75Z-7548-BA Bearing Assy - Clutch Release

You can Select Your Vehicle to check if F75Z-7548-BA fits your vehicle.

To remove and inspect the transmission, first, detach it from the vehicle. Inside the clutch housing, twist the release bearing and carrier assembly until resistance is felt, then continue pushing the assembly and preload spring down to detach the release bearing from the release cylinder. For models from 1997 onward, remove the retaining ring to separate the release bearing from the release cylinder, ensuring to push against spring pressure during this process. To check the clutch release bearing, hold the hub of the bearing and rotate the outer portion while applying pressure; if it does not turn smoothly or is noisy, replace it. Clean the bearing with a rag and inspect for damage, wear, or cracks, avoiding immersion in solvent as it is sealed for life. For installation, apply a light coat of high-temperature lithium-based grease to the face of the release bearing where it contacts the pressure plate diaphragm fingers, and lubricate the inner bore of the bearing and bearing carrier with lithium-based grease, avoiding petroleum-based grease. Finally, push the release bearing and carrier onto the slave cylinder until it is fully seated, and then reinstall the transmission.

Access to clutch components is obtained by removing the transmission while the engine is left in place. In case of an engine overhaul, it is advisable to inspect and repair or replace the clutch. It is good practice to replace both the engine and transmission's clutch components during removal. The transmission, however, must be removed from the vehicle since the engine has to be supported down on a frame. A clutch alignment tool is used for supporting the clutch disc that is being lifted out of its position. Then check the flywheel and pressure plate for alignment marks and scribe them if necessary. After that, remove the pressure plate in association with a clutch disc. The flywheel, pilot bearing, clutch disc lining and pressure plate are to be checked for any signs of wear or damage. Also, ensure release bearing condition and if necessary replace it with one in good condition. Clean up the flywheel and pressure plate surfaces prior to installation. Complete crisscrossing of positioning bolts tightens both the clutch disc and pressure plate accordingly at once placing them correctly onto a flywheel face.

Using the black plastic bearing retainer rear edge as a reference point, take a measurement with the clutch pedal fully up.

Disconnect the hydraulic line from the concentric slave cylinder inlet.

Hold the center of the bearing and rotate the outer portion while applying pressure. If the bearing doesn't turn smoothly or is noisy, replace it with a new one. Wipe the bearing with a clean rag and inspect it for damage, wear, and cracks. Do not immerse the bearing in solvent, as it is sealed for life and doing so would ruin it.

Twist the release bearing and carrier assembly until resistance is felt. Continue to turn the assembly further and the preload spring will push the release bearing off the slave cylinder.

If the results are less than specified, several possibilities exist, including low fluid level, a leaking slave cylinder, leaking clutch master cylinder, misadjusted clutch or pedal, air in the system, or a combination of these items. Refer to the appropriate section in this Chapter for proper resolution of the problem.

A light coat of high-temperature lithium-based grease should be applied to the face of the release bearing where it contacts the pressure plate diaphragm fingers.
