McCleod hydraulic throw out bearing adjust

I'm familiar with Mcleod, not Mcloud. Mcleod uses shims or a special piston to setup the 0.100-.240" of clearance but the bearing is in contact all the time (no spring to pull it back). The clearance is so the clutch can wear, the pressure plate fingers can move away from the clutch, and the hydraulic release bearing will move back to allow it. This is typical of aftermarket and oem hydraulic release bearings.
