The clutch disc is installed against the face of the flywheel. You must make sure that the correct side of the clutch disc faces the engine. Getting the orientation reversed will result in an inoperative condition and complete removal and replacment of the transmission. Even though we were using a clutch-alignment tool, we were careful not to allow the tool to droop under the weight of the clutch disc. When seating the pressure plate to the face of the flywheel, be certain to support the outer end of the alignment tool, if needed. It's imperative that the alignment tool be exactly perpendicular to the face of the flywheel as the pressure plate is tightened down or the transmission will be difficult-or impossible-to install.
