BW1350 Help
I got a 1350 from a 86 Bronco II that I took apart and rebuilt.
I completely disassembled the case and cleaned it, but when doing so, I forgot to mark the range selector shaft orientation to the selector cam.
So now I don't know where to index the outer lever to the inner cam.
The shaft has a pressed on arm with a pin to connect to the shift linkage.
WWhat position should the arm be in relation to the cam when the case is in neutral?

I recently rebuilt a crawl box made from a 1350 case. (125:1 is badass!!) I don't remember that being a big deal. I just worked the shaft, arm and related parts back and forth to see how they needed to move from one extreme to the other - 2HI, 4HI, N, 4LO. With my crawl box 2HI and 4 HI positions did the same thing because there is no front output, but the principle is the same. Try to set it up for one extreme or the other - 2HI or 4LO and it should be obvious how the parts should go. Hope this helps.

Thanks for the reply.
I guess the thing I need to know is in the Neutral position, where does the arm on the outside of the case end up? The customer dropped this box off and I need the arm to be in the correct position for when he re-installs it. If I know that it points straight up in N or perpendicular to the case in 2HI that would be a big help. Otherwise the floor shifter will be out of sync with the case and could cause it to burn up if its in the wrong range.

The arm swings in roughly a 45 degree arc. On both my t-cases, the most CCW position of the arm is 4LO. On mine that is straight forward. The most CW position is about a 45 degree angle pointing up and forward. This is 2HI. On mine the arm is removable but it sounds like yours is not. That actually came in handy to make the crawl box shifter work with the Novak shifter I have for it.
You should be able to verify the positions by moving the arm in all 4 positions and turning the input and outputs in each position. Or you can move the arm with the case open and see how the parts line up.
