I will resurrect this thread as the issue stems from it. I have not done anything about it as it has run sort of fine. There is no binding or anything.
After I put everything back together and installed the track frame, it was never aligned properly with the bottom rollers. Before I pulled it apart it was. The is probably 3/8"- 1/2" out of alignment (in towards the tractor too far)and now some time has passed and the chain will rub on the sprocket. Not bad, but it rubs. The diagonal brace bearing is also all jammed over one side and there is room there to move it outwards to correct the alignment.
Now I know there are shims that you put under the dead axle nut for alignment, however this is only for minor movement of the track frame. Not for 1/2" of moving it.
I have been racking my brain as to why it never went back in the same position I pulled it apart. I thought as I replaced the hub, maybe the aftermarket one was made all wrong and the sprocket was incorrectly positioned, but it projects the same distance from the tractor frame as the other side. So no issue there.
The only other thing it could be is the outer support, the bit that sits on the taper and you tighten with the nut on the dead axle. I replaced it with an aftermarket one, and it is it that aligns the track frame with the rollers.
So for the older people that remember these old designs, have they ever had an issue with track frame alignment from out of spec parts?
I did find this thread with a similar problem, but as usual, no known outcome.
I bought a D6D dozer six months ago. I thought I had inspected it fairly well before I bought it, but it seems like the longer I own it, the more things I find that I overlooked. The other day I noticed the track frame alignment is off in the rear. The sprockets on both sides are sitting to...
