Rotate the flywheel and get access to the hooking ring To disengage the release bearing from the diaphragm ring, the hooking-ring must be accessible to the operator. As it rotates with the cover assembly, the hooking ring can be in any angular position when the engine stops. A dedicated tool is needed to position the system to the proper angular position: The crankshaft rotator. Crankshaft rotator types depend on truck manufacturers

Similarly to the starter pinion, the crankshaft rotator engages in the flywheel tooth ring.

When in place, the crankshaft rotator is activated by the operator to rotate the flywheel and clutch assembly and obtain the appropriate positioning of the hooking ring.
