Pressure Plate

The pressure plate service process begins by taking out the engine-mounted transaxle followed by clutch cover removal along with clutch disc extraction using bolt matchmarks until spring tension releases allowing a careful clutch cover and clutch disc retrieval without clutch disc drop. The service starts with release bearing separation from the fork before individual removal of both components. The final steps include release fork support and boot extraction. Vernier calipers should measure the depth of clutch disc rivet heads for 0.3 mm (0.012 inch) minimally; replace the disc when measurement falls below this standard. A dial indicator allows inspection of clutch disc runout without exceeding 0.8 mm (0.031 inch) while the inspection of flywheel runout should not exceed 0.1 mm (0.004 inch) leading to a new flywheel replacement. When measuring the diaphragm spring for wear it must not exceed limits of 0.5 mm (0.020 inch) depth and 6.0 mm (0.236 inch) width before replacing the clutch cover. When performing visual inspection of the release bearing turn it by hand with axial force applied and if wear symptoms are detected then replace it. When installing the clutch disc, use Special Service Tool: 09301-00210 to mount it on the flywheel. Then position the clutch cover and flywheel matchmarks correctly before tightening the 6 bolts in sequence to 19 Nm (195 kgf-cm, 14 ft. lbs.) while making sure the disc maintains center position. A dial indicator should be used to examine diaphragm spring tip alignment with a maximum permissible non-alignment of 0.5 mm (0.020 inch); Special Service Tool: 09333-00013 can be used for any required adjustments. Use the boot and support the release fork within the transaxle. Apply release hub grease (Part No. 08887-01806 or equivalent) to the release fork and hub contact and release fork and push rod contact and release fork pivot points. Finally, impose clutch spline grease (Part No. 08887-01706 or equivalent) to the input shaft spline. Install the release bearing and fork to the transaxle before you reposition the transaxle to the engine.
