Accessing the clutch components typically involves removing the transaxle while leaving the engine in place, except when the engine undergoes a major overhaul. In such cases, it's advisable to inspect and replace worn clutch components due to their relatively low cost compared to the labor-intensive access process. To proceed with the engine in place, begin by removing the release cylinder without disconnecting the hose. Next, extract the transaxle from the vehicle, ensuring engine support during removal, either with an engine hoist or a jack under the engine, using a piece of wood to distribute the load. Retain the release fork and release bearing on the transaxle for now. To facilitate clutch disc removal, insert a clutch alignment tool through the disc hub. Carefully examine the flywheel and pressure plate for indexing marks; if absent, create scribe marks to ensure alignment during reinstallation. Loosen the pressure plate-to-flywheel bolts gradually in a diagonal pattern to release spring pressure, then remove the bolts, followed by the pressure plate and clutch disc. During inspection, assess the flywheel for damage and, if slight imperfections exist, consider resurfacing by a machine shop. Inspect the clutch disc lining for adequate thickness, rivet condition, and signs of damage, replacing it if any doubts arise. Replace the release bearing alongside the clutch disc. Inspect the pressure plate's machined surface and diaphragm spring fingers for damage, replacing the assembly if necessary; minor glazing can be removed with emery cloth. When a new pressure plate is indicated, factory-rebuilt units are available. For installation, ensure clean, oil-free surfaces on the flywheel, pressure plate, and clutch disc, handling them with clean hands. Properly position the clutch disc and pressure plate using an alignment tool, then finger-tighten the pressure plate-to-flywheel bolts, working around the pressure plate. Center the clutch disc with the alignment tool and tighten the bolts gradually in a criss-cross pattern to the specified torque. Remove the alignment tool, lubricate the release bearing's inner groove and release lever contact areas with high-temperature grease, and place grease on the transaxle input-shaft bearing retainer. Proceed to install the clutch release bearing, transaxle, release cylinder, and all previously removed components, securing all fasteners to the recommended torque specifications.
