Abstract
A backing plate for a friction clutch pack includes a shoulder or flange through which a plurality of radial drain passageways extend. The radial drain passageways intersect a circumferential channel which collects hydraulic fluid from the friction clutch. The radial passageways, assisted by centrifugal force, direct hydraulic fluid flow radially outwardly, away from other friction pack clutches and thus prevent such fluid from creating drag and causing increased spin losses as it flows to and through disengaged clutch packs.
