  Q: How to service and repair the pressure plate on Toyota Tundra?

  A: The procedure of pressure plate servicing requires first freeing the transmission from engine position before unbolting the clutch cover and Clutch Disc by marking the flywheel with clutch cover as you loosen each bolt set one turn at a time to release spring tension so you can pull everything off without letting the clutch disc drop. First disconnect the transmission by removing the boot and clutch release fork and bearing before taking out their clip from the bearing. The clutch disc must be checked for wear and damage by measuring rivet depth as the minimum acceptable standard is 0.3 millimeters (0.012 inch). A new clutch disc should be installed if this measurement is not achieved. Verify clutch disc runout using a dial indicator while checking for values within a range of 0.8 mm (0.031 inch) and assess the flywheel runout that should not reach beyond 0.1 mm (0.004 inch) and consider a new flywheel if needed. The pilot bearing needs to be checked through manual rotation; if it shows signs of stiction or resistance it requires replacement while using tools 09303-35011 and 09304-30012 along with a hammer to remove and install the new bearing until smooth rotation occurs before torquing the two new bolts to 85 Nm (850 kgf-cm, 63 ft. lbs.). You must check the diaphragm spring for wear by measuring its maximum depth against a specification of 0.6 mm (0.024 inch) and maximum width against 5.0 mm (0.197 inch). Replace the clutch cover if warranted. To check the clutch release bearing's condition you should manually turn the component; if replacement is needed proceed with the necessary steps. Place Special Service Tool: 09301-0110 in the clutch disc to install it on the flywheel while matching the marks between the clutch cover and flywheel. Then apply 19 Nm (195 kgf-cm, 14 ft. lbs.) torque to the 6 bolts in the specified order until the disc stays centered and the tightening remains even. Inspection of the diaphragm tip alignment with dial indicator measurement requires maximum nonalignment to stay under 0.5 mm (0.020 inch). Adjustment using Service Tool: 09333-00013 can be made if necessary. Apply RELEASE HUB GREASE (Part No. 08887-01806 or equivalent) to the release fork and hub contact while CLUTCH SPLINE GREASE (Part No. 08887-01706 or equivalent) should be applied to input shaft spline. The final steps involve attaching the transmission to the engine after installing the transmission boot as well as clutch release bearing and clutch release fork while securing the clip to the release bearing.
