hi lo gear (51 teeth) replacement on YM2000

[yanmardoug]

Can anyone advise me or guide me to a procedure for replacing the hi lo range gears for my YM 2000. When I bought the tractor, the previous owner had installed a semi-permanent metal cable to pull the hi lo shift handle back so that it would stay in gear in hi range. Inspection revealed that the hi lo shift fork was severely worn but it did not appear that the gears themselves were worn. I replaced the hi lo shift fork thinking that the fork was worn sufficiently that it was not moving the gear far enough to fully engage. Despite the fact that the shift fork, ball, and spring are all new and it feels as though the ball firmly engages both d騁entes, it still will not remain in hi range at all without manually holding the shift lever firmly in the rearward position. The implication is that one or more of the hi range gears is worn and must be replaced. One of those gears is the "hi lo gear (51 teeth)" depicted as item number 4 in the hoye diagram of the "transmission_internal" for the YM 2000.

Long ago Danny1 posted that the only remedy on YM2000 is to replace both gears. I think that would be the sliding hi/lo gear and the fixed high gear it meshes with.

Seemingly will require replacement of one or the other or both gears. The 51 tooth hi lo gear (#4 on hoye's diagram) and the 28 tooth hi lo gear (# 25 on that diagram). The question is, how to do that.
