What is the procedure of tightening the tracks as in how much to tighten them and is there a way of measuring them so both sides are even.they are sagging pretty bad.

It does, you can use code to post it, somewhere on here is a screen shot of it or you can do same from your file directory. img src = paste the direct link here, then close the parentheses. < code here> Its hard to type the code as a sample.

I saw the photo and the tracks are very loose. You may have a worn out undercarriage, you'll need to measure it to see what is what.

That is an early 6 cylinder model judging by that early to mid 40's grill. It has mechanical adjusters and you will need remove the adjuster covers, likely soak the large threaded rod with penetrating oil or whatever you like to use to un-seize assemblies like these, then using a large wrench on the flat areas of the adjuster, you'll need to turn it so it expands the idler or moves it out. First thing you should check is to see if its already been let out all the way, if that is so, then you will have to repair the track components to get the slack out, that would indicate max wear if all the way out.

Haven't messed with on of those, but if it has a mechanical, or threaded adjuster, Billy nailed it. You may also have to use some heat to get the threaded rod to loosen if it hasn't been moved in awhile.

If I remember right, art one time, the mechanical adjusters could be replace with hydraulic ones. If that's the case, then look for the grease fitting and put some grease in it to push the idler out ad tighten the tracks.

As far as how much to adjust, I usually just go to where there is a slight bit of sag, usually 1 inch or so, between the return rollers. Judging by the amount of space on the track frame, in front of the idler, you should have plenty of adjusting room based on the current amount of sag. In fact you'll probably be surprised how little out of adjustment they actually are.

Good luck...if it has the threaded adjusters, you'll need it...
 
Should also add that for correct track tension, they should be adjusted so that there is, 1 1/2" to 2" free play when you pry up on the track chain at the top rollers on the track frames, there should be that much space, too loose, too tight are both no good, and will accelerate wear.
 
These are something, the older mechanical type adjusters, I've seemed to have had decent luck freeing them up though, the recoil spring is something else too, there is a tool or jig you can build for it if it needs to come out, going from memory its in the old books on these, same kind of inertia when a sprocket comes off one of these tapered axles. This wide gauge model tractor does have all of the adjuster covers in place, threads might be easier to work with, it seems to have rear hydraulics like an ag model, (can't see if its got the smaller idlers, does not look it). Electric start pony, generator/alternator, don't recognize the blade, bucyrus-erie, la-plante-choate or similar from that era.
 
Here you go, there seems to be some nice original Parts Catalog's listed, I would avoid Jensales, spiral bound manuals, they don't compare to even a good used original. Serviceman's Reference Book, and Operators Instructions are the other 2 needed. Be sure to reference your tractors serial number and match it to what the manuals cover, and it will state that on the cover. The SRB in the first listing looks like a copy, or reprint, it has a much later cover style, so while it may include all tractors of that run 8U, 9U, you may want to check to insure its legible, pictures included. CAT was offering re-print manuals for most older tractors and equipment, the print quality would definitely be better, I have one of their reprints by Midland Press, they re-printed these prior to CAT taking them back in house and it was decent quality.
D6 9U manuals
 
I have the original serviceman's reference manual for that tractor, $30 + shipping.

I also have an 8u parts manual, I'd think most of it is the same as the 9u.

Also have a electronic copy of the matching D311 engine manual.
