Yes, the lay-gear is also tapered, its hard to measure but i have about .005inch taper wear on most of the teeth. My thoughts are, if this is common with td/tf gearboxes its why many complain of first gear problems i have the MG Y box now but the first gear and lay-gear are missing. Can any one give me the measurement of the neutral to first gear selector shaft indents, mine measure .670inch This is also hard to measure accurately but its in the ball park. I will be replacing lay-gear, first and slider. Has any one used the rebuild lay-gear?? Saltiga
