First is gone ... grinds going in, pops out when I let the clutch out.
I've done lots of linkage adjustments, replacements, etc. etc. Followed the Pelican Tech article to open the tranny and check out the gears. This is what I see... dog tooth: slider: I'm assuming I'll be replacing the syncro ring, and the dog tooth gear. And the slider is still ok. Yes? No? Any recommendations on where to pick up the parts? |

OK - so I put the gears all back together. The fingers feel snug in the slider. Tried measuring the slider-to-1st gear gap - kind of difficult. Came up with .125" to .15"
Is there something more exact I could look at or measure? |

Came up with .125" to .15" Is there something more exact I could look at or measure? That sounds like way too much. The slider is typically closer than that. Try this......put it in first gear so the shaft is in the detent, loosen the shift fork, push the slider firmly onto first gear and then re-tighten the fork. Now take a look and you will find that it's way closer. Fine tune from there. If the slider is not all the way against the gear when the shaft is in the detent it will pop out of gear all the time. Goin' by memory..... The shaft must be in the detent the slider must move all the way to the gear while shaft is detented and relaxed It must not rub on the syncro reverse must properly engage when detented |

There is a indentation on the shaft for the fork bolt. |
