915 tranny 5th/rev detent question
Greetings Pelicans,
Just wrapping up a full rebuild on my 1983 SC 915 box (with kudos to Pete Z. and his tutorials). I think I made a last minute mistake with a detent.
This is after a long process of pinion and main shaft bearing repair, one piece thrust plate, mostly new bearings and synchro/slider replacements. I also assembled and disassembled many times adjusting final drive preload, pinion depth and backlash to get it just right.
Problem: I just mounted my center case section and installed the final 5th/reverse gears and forks. About to check the final clearance between reverse idler and slider gear and find that the fork and rod are not held in place.
My 1/2 and 3/4 shift rods are interlocked so only one can be moved at a time, so I think those detents are correct, but the 5/rev rod moves freely.
Question: did I mess up the last detent(s)? Isn't this rod supposed to be held in place by a detent so I can set that gap? Under what shift positions should it be locked? How about free too move?
Further: I checked for the detents to be visible and in place before installing the rods, but don't remember installing something called a "sleeve". If I didn't, I wonder if the pin is out of place and not pushing the detents far enough?
Would appreciate help from somebody who has been through this. Thanks.
Rick
