[quote="48farmallH"](quoted from post at 09:41:25 06/29/17) I have had my 44 pop out of first gear a few times in the last couple years when pulling but when it cost me first place at the last pull I decided enough was enough. Had done some research on the solution but most advice was the spring and ball (which I replaced with a heavier one last year), or just put a bungie cord or load binder on it.
I pulled the transmission cover and shift rail cover, removed the shift rail block/holder, and then the 1st/reverse shift rail.
In my opinion there were two problems, wear on the shift rail and the original machine job was too close. After some measurements I came up with .095" left that first gear could still engage while still have .020" left of play.
I welded the 1st/neutral gear slots on the shift rail and then roughed the shaft back in on the lathe, finish ground the od, and milled the slots back in. The 1st gear slot/detent I moved back .060" and increased the depth .015".
Got everything back together last night and it really locks in 1st now!
I will upload some pictures in the parts and peices gallery. [/img]
