Make sure the clutch is facing the correct direction. The tool should stick all the way through the spines on the disc. Step 2: Then place the clutch on the flywheel, and engage the alignment tool into the pilot bushing or bearing in the center of the crankshaft. Push the clutch tight to the flywheel. Step 3: With the clutch on the flywheel, install the pressure plate to the flywheel and start the bolts. Step 4: Wiggle the alignment tool to make sure it is fully engaged and seated in the pilot bushing and bearing. Tighten the pressure plate bolts in a criss cross pattern and then torque to spec.Tip: Before insert the tool into the clutch disc, please choose a suitable adaptor size to fit pilot bearing and connect with expanding mandrel. The clutch alignment tool stays in the clutch until you are ready to install the transmission. While the pressure place should hold the clutch from moving, don’t take the risk of pulling the tool out too soon. Once the transmission is ready to install, pull the tool out, and slide the transmission into place.
