well, I was quite amazed that I got the adjusters to move, with very little effort or fuss...

my reproduction service manual does not have an adjustment proceedure, so I am not sure if i have these too tight or not.. here are pictures of both sides..

Looks about right for tension adjustment.....should be able to pry the track up 1-1/2 in to 2 in. over the carrier roller.

Maximum recommended adjustment extension is 4 in. hex nut to hex nut.

You might want to back that critter up 5-10 feet and then take another look at the tracks. By backing up, just about all the slack will wind up on top. I've never seen that in any of the books, it's just something I've noticed over the years. It's also easier to turn the adjusters with the slack on top.

thanks

ol grump--i thought that by backing up you put tension on the top track and pull the slack out---going forward puts the bottom track in tension and slacks up the top?? :noidea:

Recommendation is to drive the tractor back and forth to equalize adjustment then re-check.

You're correct. I pooched that one and didn't realize it 'til later yesterday morning. I forgot to mention that pulling forward would put the slack on the top of the tracks. Should'a remembered that!

I'm in the middle of taking a link out of the tracks on my D4, got one side done yesterday and today I'm gonna have help on the other side. The reason is that with the 5 roller frames the tracks were brushing against the rear of the "C" frame, not because the chains were worn out. It was either that or lengthening out the side bars and I thought it would be easier to shorten the tracks. .now I'm wondering if lengthening the side bars wouldn't have been easier๐Ÿ˜†

Paul--i just adjusted the tracks on my D3B yesterday and final move was forward to get the most slack.thats why i was up on the subject. I had them very loose from the winter when i was pushing snow.
Yep--we choose a course of action and it may or may not be the best way to go!! ๐Ÿ˜†
Right know i am trying to pull the rear pin on the lift cyl. so i can reseal it---can't believe I snapped a 1/2 grade 8 new bolt pulling on the pin---i guess some heat is next.

Going by the first picture I would tighten the track a bit more, the sprocket looks to be worn way out of pitch and looks to be built up,be careful of rocks or the like as with no belly guards it is easy to crack an oil pan or casing.

I leave the cylinder in situ,it is easier to undo the gland with the cylinder held solid in place,with the gland undone take the rod pin out,block up the cylinder and remove the rod,put the eye of the rod in the drawbar and block it up at the piston while you undo the nut.

AJ--thats how i did my 941b cylinders as there were 4 bolts holding the gland on
but the d3b has a screw on crown thats at 550 '# torque and I don't even have a pipe wrench with big enough jaws to get it off.
