Transmission Bearing Lube Transfer Hub

摘要

Disclosed herein are several examples of a transmission lube transfer hub and a method for modifying a transmission to overcome premature failure problems. The modification in one example includes significant modification to a lube transfer hub and replacement of a bearing assembly with a bearing assembly having a larger outer diameter. Modification may also include modification to the transmission casing by plugging of one or more clutch feed passages and drilling of cutoff passages past the plug. Modification may also be made to a ring gear hub and/or clutch hub to allow for a bearing assembly having a larger width.

1. A transmission lube transfer hub comprising:
a. a longitudinally forward face having a plurality of surfaces defining fastener voids there through and a surface defining a shaft bore there through; b. a radially outermost convex surface; c. a cylindrical radially outward convex casing bulkhead engagement surface; d. a cylindrical radially inward hub engagement surface; e. a surface defining an circumferential oil channel radially inward of and formed in the casing bulkhead engagement surface; f. a plurality of oil passages extending from the oil channel to the hub engagement surface; g. a planar and cylindrical bearing engagement surface; and h. wherein the lube transfer hub does not extend longitudinally forward of the forward surface of the bearing engagement surface.
