<p>A thrust washer combination employing three thrust washers (28,70 and 72) is provided for maintaining separation between and for transferring axial thrust to a mainshaft (2) that has been imparted to either one adjacent floating mainshaft gears (12,18) of a change gear transmission (100) respectively by a clutch assembly (20) or (22) during the process of selectively clutchingly engaging one of gears (12,18) to the mainshaft to effect the rotation thereof. Gears (12) and (18) have respective adjacent flanges (42) and (44) that extend towards mainshaft (48) with thrust washer (28) being contained in an annular groove (42) therebetween and keyed for rotation with mainshaft (2) and thrust washers (70) and (72) positioned on opposite sides of flanges (40, 42) and held thereagainst by retaining rings (74) and (76) respectively. <IMAGE></p> |
