5.9 magnum automatic crank

Where is the bearing in this setup?
The bearing we are talking about is the pilot bearing that installs at the back of the crankshaft and the transmissions input shaft goes into and rides on within.
The old bearing “Sweats” and the new bearing is a roller.
In the clutch itself?
The clutch itself has no bearings. Just levers, fulcrum points and springs.

There is the “Throw out bearing” that rides on the inout shaft. When you press the clutch pedal down, the mechanical linkages press the clutch fork backwards and the “Throw out bearing” goes forward to press against the pressure plates fingers to release the clutch. This is the clutch’s disengagement.
Or on the outside betweens the clutch and the flywheel.?
Behind them both.
That is the approximate area the throw out bearing is placed in the resting position. When pressed inwards to disengage the clutch, The bearing rides the input shaft forwards and presses on the pressure plates fingers.
