I am putting in a new input shaft in my 530 ck and my manual I&T that is says to put the chamfered edge of the synchronizer toward the snap ring. I can't tell any difference in the synchronizer other than one edge is a smooth chamfer and the other edge is a stair step chamfer. So which is the side that goes toward the snap ring? Help! Also thanks!
It originally had the stair step forward but it has also been into and was jumping out of gear. So I want to do it correct.

The hub of the syncro should have a chamfer one one side and a straight side on the other. The chamfer should go to the snap ring.

If you had a gear jumping issue I personally would replace the synchronizer assembly as it probably has an abnormal wear to the gears from slipping out.
You probably would be disappointed if the gears still jumped after all that work, just my opinion. Good luck,

Thanks Mel but my synchronizer looks good on the gears. No beveling of the spline or dubbing off the ends. The shift fork groove looks good also. It also has a good snap to it when shifted. I think someone replaced it sometime back and did not replace the gear shaft. My syncro has BOTH sides chamfered. The one side is a smooth chamfer and as I said before the other side has a stair step type of chamfer. The stair step side was to the snap ring side or front but wasn't sure if that was correct. If I could reverse it the side that was for reverse would now be forward which would be the hardest pull side. The syncro looks to be the same except for the stair step chamfer.

Quoting Removed, click Modern View to see

You could just change the collar if you like and reverse the driven sides, just remove the expander springs and slide it apart and reverse it. I think they want the wide side of the carrier to go toward the washer on the shaft and I would install it that way. If you reverse the collar make sure the dogs are in place and the springs installed so the dogs are tensioned out.

Thanks Mel. I will probably do that. It just looks too good to replace.
