ABSTRACT:
A cooling system for an annular stator housed within a transmission casing includes a first curved tube sufficiently sized to at least partially circumscribe the stator when the tube is placed within the casing. The first tube has a plurality of circumferentially spaced fluid openings. An intake conduit connects the first tube to the transmission casing to deliver fluid through the tube for flow through the fluid openings to cool the stator. Preferably, a second like curved tube is also provided and a connector tube connects the first and second tubes to allow fluid flow therebetween. A method of assembling a cooling system is also provided.
