  Q: How to overhaul the clutch disc on Toyota Matrix?

  A:

  The clutch disc repair process starts with manual transaxle removal and then requires the removal of clutch release components including the fork along with its bearing unit from the transaxle assembly. Remove the clutch release bearing assembly from the clutch release fork after which you should extract the transaxle assembly release fork support. Detach the release bearing hub clip along with the clutch release fork boot before you can remove the clutch cover assembly by matching the marks on the flywheel sub-assembly then relaxing spring tension by loosening each set bolt by one full turn until you can remove the six bolts to extract the cover assembly while avoiding dropping the clutch disc assembly. Before detachment of the clutch disc assembly keep the lining part as well as the Pressure Plate and flywheel sub-assembly surface free from oil and foreign materials. Vernier calipers should be used to examine the clutch disc assembly by measuring rivet head depth which must stay below 0.3 mm (0.012 inch) or require new clutch disc assembly replacement. Table 1 illustrates the installation procedure for the transaxle assembly. First insert the disc into its proper direction. Then use the dial indicator to check runout which should remain below 0.8 mm (0.031 inch); replace if necessary. Verify the diaphragm spring wear of the clutch cover assembly through vernier caliper measurements; the fixture depth must exceed 0.5 mm (0.020 inch) and width must exceed 6.0 mm (0.236 inch), but the assembly needs replacement in case of non-compliance. A dial indicator should be used to measure the flywheel sub-assembly runout which should be under 0.1 mm (0.004 inch); replace the part if this limit is exceeded. The clutch release bearing assembly should be checked by hand rotates while applying axial force so you can replace the release bearing assembly only when needed. For clutch disc assembly installation use Special Service Tool: 09301-00210 by properly placing it into the flywheel sub-assembly. First install Special Service Tool 09301-00210 by inserting it properly into the flywheel sub-assembly. Then use a torque wrench to tighten the six bolts starting with the one close to the knock pin to a torque of 19.1 Nm (195 kgf-cm, 14 ft. lbs.) while checking that the disc remains centered during the entire procedure. The clutch cover assembly requires inspection with a dial indicator for diaphragm spring tip alignment during which maximum non-alignment must not exceed 0.5 mm (0.020 inch). To adjust the assembly properly use Special Service Tool: 09333-00013. The transaxle assembly receives the release fork support which must be torqued to 36.8 Nm (375 kgf-cm, 27 ft. lbs.). The next step involves mounting the release bearing hub clip and clutch release fork sub-assembly during which time release hub grease (Part No. 08887-01806) should be applied to essential contact points. Before installation of the bearing onto the fork, the transaxle assembly and release fork must receive clutch spline grease (Part No. 08887-01706) on the input shaft spline. Then, check for smooth fork movement before final installation. Afterward install the clutch release fork boot together with the manual transaxle assembly.

  Q: How to service and repair the clutch disc on Toyota Matrix?

  A:

  Start clutch disc service and repair by first taking out the manual transaxle assembly then removing the clutch release fork sub-assembly containing the removal of clutch release fork together with clutch release bearing from the transaxle assembly. The service begins with removing the clutch release bearing assembly from the clutch release fork before extracting the release fork support from the transaxle assembly followed by the release bearing hub clip and clutch release fork boot. Begin to remove the clutch cover assembly by lining up the matchmarks of clutch cover and flywheel sub-assembly while loosening all set bolts one round at a time until spring tension frees up. Afterward remove the 6 bolts to extract the clutch cover assembly maintaining the clutch disc assembly from falling. You should disassemble the clutch disc assembly while maintaining the oil-free state of the Pressure Plate as well as the lining part of the clutch disc assembly and the flywheel sub-assembly surface. You need to inspect the clutch disc assembly rivet head depth with vernier calippers to check if it exceeds 0.3 mm (0.012 in.). If not, replace it. Put the clutch disc assembly into the transaxle assembly along the correct installation path and verify its straightness with a dial indicator that should not show more than 0.8 mm (0.032 in.) deviation. Check the clutch cover assembly for wear and verify the diaphragm spring depth meets 0.5 mm (0.020 in.) while the width should be 6.0 mm (0.236 in.) to warrant a replacement. A dial indicator should measure the flywheel sub-assembly runout and maintain a reading below 0.1 mm (0.004 in.) while the clutch release bearing assembly needs inspection for damage and wear and its operation needs replacement if needed. You can install Special Service Tool: 09301-00210 by inserting it first into the clutch disc assembly and then into the flywheel sub-assembly but maintain correct orientation during this process. Tighten 6 bolts between the clutch cover assembly and flywheel sub-assembly following the specified order to 19 Nm (195 kgf/cm, 14 ft. lbs.) while confirming disc centering through even tension. Check the diaphragm spring tip alignment of the clutch cover assembly using a dial indicator with roller instrument by adjusting it with Special Service Tool: 09333-00013 when necessary. Socialize the release fork by affixing it to the transaxle assembly at a torque of 37 Nm (375 kgf/cm, 27 ft. lbs.). Subsequently attach the release bearing hub clip after which the technician should attach the clutch release fork sub-assembly and apply Toyota Genuine Release Hub Grease or equivalent to key contact points. Before implementing the clutch release bearing to the transaxle assembly users need to apply Toyota Genuine Clutch Spline Grease or equivalent to input shaft spline followed by checking smooth operation of the release bearing after installation. You must install both the manual transaxle assembly and the clutch release fork boot at the end of the process.
