ABSTRACT:
A fluid operated friction clutch has a power piston which is selectively pressurized to urge a presser plate into abutment with a clutch disc pack to enforce frictional engagement thereof. The presser plate has an inner annular surface which is axially aligned with an adjuster sleeve which frictionally engages a clutch hub. The adjuster sleeve has a plurality of fingers or tangs which engage the presser plate to enforce relative movement between the sleeve and the hub until full engagement of the clutch pack is attained. The sleeve also has a lip or tang which limits the retraction of the presser plate from the clutch engaged position thereby establishing the free-running clearance of the clutch pack.
