IMPROVED TRANSMISSION THRUST WASHER AND LOCKING MEANS THEREFOR

摘要

An improved elongate key (92) is provided for securing thrust washers to a mainshaft (48) of a transmission (100). Key (92) has a substantially triangular cross-sectional configuration having rounded intersections between adjacent surfaces rendering it easily insertable axially through keyways defined between external axially extending grooves (66) in mainshaft (48) and aligned internal grooves (86) in the thrust washer which itself is preferably provided with rounded corners (90) to enhance the strength thereof.
