ronm - 10/16/2021 22:03 In watching your video: Top shaft looks OK if they can unplug the lube holes. The shifter fork is the late style that goes with the 3X5 syncros, but the syncros are not 3x5...the shifter has the notch in the top that slides in the long spacer on the bolt. keeps it aligned. I saw the bolt & spacer laying there. The triangle piece they can't identify looks like a piece of the shifter, maybe off the original one in a previous failure-the one there isn't original... 3X5 syncros have splines on the inside of the plates, the old style have 4 tangs. They are the parts with the "little fricition disks"... The blue area on the PTO shaft is from heat-treating, don't worry about it...nothing runs there. They all look like that. The bottom shaft gear looks like 6&8, you didn't show it very well. Was it jumping out of 6&8? (It finally dawned on me this is a syncro, not a quad-range...) Make sure they set up the axle bearings with the "lead ball" method. should be in the manual, or in a 4440 manual for sure.
