CLAIMS: 1. A carrier assembly comprising: a gear carrier having a central axis and a pair of axially spaced-apart plates, the pair of axially spaced-apart plates having inward surfaces that are axially spaced apart to define an axial gap, the pair of axially spaced-part plates having a plurality of planetary bores on a plurality of planetary axes parallel to and radially outward from the central axis, the planetary bores having a planetary bore diameter; a plurality of shaft assemblies disposed on the planetary axes and mounted within the planetary bores of the gear carrier; wherein each shaft assembly includes: a journal bearing shaft mounted in the axial gap and having a pair of compliance grooves extending axially from opposed axial ends of the shaft, an inner cylindrical surface of each compliance groove defining a shaft mounting surface; and a pair of collars, each collar having a mounting socket mating the shaft mounting surface and an external collar surface matching the planetary bore diameter. 2. The carrier assembly according to claim 1, wherein the pair of collars have an axial restraint flange for abutting an outer surface of the axially-spaced apart plates of the gear carrier. 3. The carrier assembly according to claim 2, wherein: the journal bearing shaft has an internal shaft bore with an internally threaded axial end; and wherein each shaft assembly has a pair of bolts with externally threaded shanks engaging the internally threaded axial end of the internal shaft bore. 4. The carrier assembly according to claim 3, wherein at least one bolt of the pair of bolts includes an oil passage in communication with a source of oil within the gear carrier. 9 Date Recue/Date Received 2021-01-25
