A method of manufactore of, and apparatus for, a torque converter assembly having an improved reactor assembly. A torque converter is disclosed having a stator which has improved and simplified casting and machining requirements. A stator hub is provided having a cylindrical bore substantially coaxial with the axis of the transmission shaft to which the torque converter is mounted. An overrunning clutch and thrust bearing cartridge assembly is provided to be fitted into the stator hub bore. The overrunning clutch provides improved lubrication on both sides of the clutch engaging element surfaces, either rollers or sprags, between the inner and outer rings which form the clutch races. Wear surfaces within the clutch assembly are stamped steel instead of aluminum. Clutch load is increased by increasing the roller or sprag dimensions in the direction of the stator axis, while maintaining the same stator hub width. Thrust bearings are mounted to the outside of the overrunning clutch.

A method of manufacture of a reactor assembly, adapted to be mounted on a stationary sleeve between an impeller and a turbine in a torque converter, comprising the steps of: (a) providing a reaction device; (b) forming an essentially cylindrical axial bore in the hub of said reaction device, said bore being substantially free of steps or shoulders; (c) mounting a cartridge clutch and thrust bearing assembly in said bore as a single unit independent of said reaction device; (d) permitting the reaction device to be engaged in a fixed position to prevent freewheeling relative to said stationary sleeve or disengaged from a fixed position to permit freewheeling by providing a plurality of bearings for the clutch, said bearings each having an axial dimension substantially the same as the axial dimension of the reaction device bore; (e) providing lubrication to both sides of the clutch bearings in a flow path around thrust bearings of said assembly and axially past said clutch bearings; and (f) providing moving parts which have contact surfaces made of hardened materials. In a torque converter having an impeller, a turbine and a reactor assembly adapted to be mounted therebetween on a nonrotatable sleeve, the reactor assembly comprising: (a) means for reacting to coupling fluid flowing between said impeller and said turbine, said reacting means having formed therein an essentially cylindrical axial bore having a substantially constant diameter; (b) means for engaging and disengaging said reacting means to restrict and permit free wheeling motion of said reacting means relative to the nonrotatable sleeve, said engaging and disengaging means received within said reacting means bore and adapted to engage said nonrotatable sleeve, said engaging and disengaging means comprising: (i) cam means for wedging said reacting means relative to said nonrotatable sleeve in an engaged position and releasing said reacting means relative to said nonrotatable sleeve in a disengaged position, (ii) retention means, having inner surfaces and outer surfaces, cooperating with said cam means surfaces and outer surfaces, cooperating with said cam means at said inner surfaces for retaining said cam means between said reacting means and said nonrotatable sleeve, and for providing alignment of said cam means relative to both sides of said cylindrical bore, (iii) bearing means for bearing said reacting means against said impeller and against said turbine, said bearing means mounted on outer surfaces of said retention means, said cam means enclosed by and mechanically engaging said retention means and said bearing means mounted on said retention means so as to cooperate to form an engaging and disengaging means cartridge unit mountable as a single unit independent of said reacting means within said cylindrical axial bore; and (c) contact surfaces between said engaging and disengaging means and said reacting means, said engaging and disengaging means and said reacting means being immovable relative to each other at said contact surfaces.
