Going to have to split tractor to get top shaft out. Noticed that
shifter cam weren?t ever changed out from first rebuild 8 years
ago. Deere only has some limited parts left in existence, I
think like 12 only left. So how would one go about fixing what I
got if they did run out. Seen some used ones but idk what to
look for wear wise . I have some pics of what I?m talking
about used ones and what in my tractor
 

NOT sure what the issue is here, I've split and repaired those transmissions every which way and sideways, and don't recall dealing with a failed R33392.

DEERE still has 'em for the big bucks, if you actually need one, are you going to buy new or look for used?
 
Parts guy says it worn where dimples are I think he is full of
it.told him to put metal ball and spring instead of pointer and
spring.
 
Is this cam something that wear out over the years or not so
much. My problem is that idk how to tell if mine is worn, they
did put new top shifter on forward and reverse synchro
drums.idk if their is a picture of one that is excessive wear on
it that you couldn?t use, that way I could compare that to mine.
Idk i have had different mixed reviews about it. Problem that
cause tractor to crack the shift collar on top shaft was hard
shifting like for instance if you were in fifth gear and want to go
down to eight gear the trans didn?t want to shift smoothly
going down into eight gear unless tractor was idle down, didn?t
do it in that exact combo of gears would do it any which you
shifted it.
