Weird, this the like the third thread on throw bearing "to spring or not to spring" in the last month.

Maybe it's a springtime thing?

Short answer, YES, spring on it. Why is this a complicated issue? Clutchs have been done this way for a 100 years.

The throw out bearing must NOT ride on the pressure plate. I challenge ANYONE and that INCLUDES Ford tech pages, advice or quotes from Ford trained mechanics or anyone else who say's otherwise. It's BS that "modern" throw out bearings are "designed" to run with zero clearance to the pressure plate fingers. On some Mustangs with cable actuation it is virtually impossible for the auto adjusted clutch pedal to leave you with ANY clearance to the pressure plate. IF you follow Fords auto adjustment procedure your throw out bearing WILL turn constantly. Ford knows this, their answer is: It's supposed to be that way. Again, BS, thats the easy answer to avoid a serious design flaw Ford has no intention of fixing.
