Q: How to remove and replace Pressure Plate and Clutch Disc on Nissan Sentra?A: One should remove a clutch assembly, usually accessed after removing the transaxle, with the consideration to replace unless they are new or almost new due to the effort needed for access. One of these is concentric release cylinder. The flywheel and pressure plate should have indexing marks or you would make marks for proper alignment when installing. Remove the pressure plate and clutch disc, through loosening the pressure plate-to-flywheel bolts progressively in crisscross pattern before that perform thorough inspection. In case of doubt, replace them if concerned about it because they might show signs of damage such as wear on the clutch disc, loose rivets, distortion and other damaged parts like cracks happened either on the clutch disc or on flywheel. Moreover, replacement should be for release cylinder/release bearing alongside this part. Inspect friction surface for any issues and check the pressure plate; if there is notable damage or overheating observed, replace the complete pressure plate assembly. Make certain that both surfaces where flywheel and pressure plate has been machined are oil and grease free before installing them along with clutch disc using an alignment tool. Gradually tighten all bolts from the Pressure Plate to Flywheel in a criss-cross pattern, centering your Clutch Disc then remove your Alignment Tool prior to re-installing this Transaxle among other assemblies ensuring that every fastener complies with torque specifications.
