H CLUTCH UNIT Removal Note Clutch cover and disc 1 . Install the SST. 2. Hold the flywheel by using the SST or equivalent. e 3. Loosen each bolt one turn at a time in a crisscross pat- tern until spring tension is released. Then remove the clutch cover and disc. Flywheel 1. Hold the flywheel by using the SST or equivalent. 2. Remove the flywheel. 3. Inspect for oil leakage from the crankshaft rear oil seal. If there is any such leakage or if the oil seal is damaged, refer to section B and replace the crankshaft oil seal. Pilot bearing Note The pilot bearing does not need to be removed unless you are replacing it. Remove the pilot bearing by using the SST. L' Installation Note Flywheel 1. Wipe the bolts clean, and apply sealant to the bolt threads. 2. Install the flywheel, and secure it by using the SST or equivalent. 3. Tighten the bolts in the pattern shown. Tightening torque: 97-1 02 N.m (9.8-1 0.5 kgf.m, 71-75.9 ft-lbf) Pilot bearing Install a new pilot bearing flush with the flywheel by using a suitable pipe. Gartner Banana
