I think I know the answer but better ask.

Its been a long time since I have done any maint on my poor old D6-B and I wanted to see how bad the chains were on the old girl.
Not sure, but I think it might be bad news.
The links are salt and I think they are D5 chains.
I measured the height of them from the bottom of the pad to theto the bottom of the link and got 3.75 inches
and measured between 4 pins (duh should have been 5) and got 73mm
Here are some pictures (sorry for the mud, didn't get a chance to clean her up last year.)

Check out my other album for some pond construction around my property. The old girl has did some good work over the years.

So, give me the bad news, can I get another few hundred hours out of her? (I really only need to clear about 30 achers of alders and build one more road and I will let her sleep forever.
Looking for some short term options.
Thanks CAT gods.......

Those probably are the D5 chains at 6.90 pitch to get the segmented sprockets.
New rail height is 4.06 in. and 100% worn at 3.70 in.
Four pin length would be 27.64 in. new (702mm) and 100% worn at 722mm.

The sprocket segments shown are definitely worn and near required replacement.

But....it does not appear that the rollers are hitting the pin bosses (unless the mud is concealing). At this point you are probably out of take up adjustment so you would have to either remove a link or shim back to adjustment range and just run it to destruction. Looks to me like you could get your required use out of whats left if you take it easy.

You sure you got SALT on there as from what I can see it looks like you got conventional sealed dry tracks,usually SALT pins have a hole in the centre of each pin for to charge them with oil, the bushes are a more important factor than the links,check the bushes as going by the sprocket wear they may be due to be turned.

and watch it! Unless you are clearing rough, rocky or steep ground, after some adjustment to the track tension, you should be able to finish your work about the time the undercarriage is finished.

If you are on rough, rocky or steep ground you can likely still get it done, just change to more of a "watch it and run it" mode.

I like the ol' D6B and would probably still have mine it it had a p/s tranny.

Which of course would have made it a D5

You could probly get away with pressing one or maybe even two links out of each side and then bring your adjust meant back in and re tighten and then run it till it drops far as the tracks. The over all tractor seems to be kept up pretty good. Are there any other problems or concerns? Once you're done with your projects what do you plan on doing with the tractor? Fix it up I hope!

The tractor itself is in good shape considering just after I bought it I had to replace the clutch packs, both final drives, brakes and all the rollers!
The motor is great, doesnt smoke at all or go down in oil.
I cant see the old girl just rust away so I will try to find her someone who will appreciate her.

How would I go about removing a link?
Is this something that can be done without bringing it to a shop?
I could just tap it out with my finish hammer right - lol
Thanks...
