4630 quad range transmission gears

chuckthisout · Mar 21, 2019

I'm working on my 4630 quad range. My
question is on the "B" and "D" range gears
on the differential drive shaft. Where
the shift collars slide on the gears, how
much wear on the teeth is tolerable? They
look bad to me but I have never been in a
quad transmission...this is all new to me.
Hopefully the pictures load. First and
second pics are D range and third and
fourth are B range. Just looking for some
guidance. Any help and advice is greatly
appreciated. Tractor seemed to shift good.

The first two pics are way to much. This is from my experience on syncro range tractors. Tom

The "D" range is always worn more. Guys speed shift them when pulling heavy loads on the road. Your going to have it completely apart to put in the "D" range so I would replace the "B" while I was in that far.

That's what I was afraid of
...just wanted some more opinions. Already have the axles off, cab off, rockshaft housing is off and it's double split already so it would be pretty dumb not to fix it while it's torn down this far. I'll probably be asking more questions in the future on this one. Thanks for the input.
