An improved single-shaft shifting mechanism (200) for shifting a multiple-speed mechanical transmission (10) is provided. The mechanism includes an axially and rotationally movable shift shaft (204) to which a separate shift block (202) is mounted for axial and rotational movement therewith. The shift block (202) is mounted to the shift shaft (204) with shoulders (210, 212) formed on the shaft and complementary surfaces (236, 238) formed on the block to take axial loading and by pairs of complementary (230, 232, 244, 246) formed on the block and/or shaft clamped together by a shanked fastener (188). The opposed surfaces (222, 248) of the shaft and block through which the shank (188A) of the fastener passes are configured to remain separated. <IMAGE> |
