Track pins are 27" from center to center over 5 pins, and I took a video. Also detailed pics to come...

Did you stretch the chain before measuring.
27" would only be 5% worn and I doubt it is that good.

I noticed the brake pedals too.
I also noticed new nuts on the gear shift quadrant. The 6U I owned (and liked very much) had a habit of hanging up in reverse with the stick moved into neutral. Then I had to remove those nuts and either move the transmission to neutral or the stick to reverse. It only did that when I shifted too quickly or vigorously out of reverse.
But new bare-metal nuts on that quadrant when everything else is painted looks suspicious to me. If all else checks out OK, be sure to drive it and be a little aggressive shifting out of reverse, just to see what happens. Having that reverse in neutral issue is not a deal killer to me, because it can be fixed by building up the bottom end of the gear selector stick, but it IS a nuisance.

As has been noted about wear on the brake pedals and new nuts on the shift quadrant it appears to be a well used machine.Unless my eyes are worse than I think it looks like a new sprocket ring has been welded on and possibly the track chain has been replaced. .at least on the side in the picture.
I'd be curious as to what the hour meter reading is.

Well I would have thought with the pedals worn like they are it has done a lot of work having said that I would be more concerned with all the work it has done if it hadnt been painted or have new tracks sprockets ect or new nuts on gear quadrant ! To me it tells me someone has looked after and worked on as it should be and someone thought it shouldnt have exposed bare metal and gave it a coat of paint all sounds like someone has looked after it but I could be wrong ?

In the latest photo's, seems to be a lot of clearance in the lift arm pivot assemblies, sprockets are definitely rounded, look at 2 links, you can see a lot clearance.
I noticed the brake pedals the other day, but going back today, I thought it was odd that the clutch lever grease fittings appear to have paint over the ends like they never been greased.
Seen as it needs a Main Clutch, I would agree with the majority, its not worth $7000, maybe half that amount?

The picture is a little fuzzy but in the sprocket picture it appears that the sprocket teeth have been welded up and reshaped. I can not see any weld where a new sprocket ring would have been welded on. Two teeth are rounded like fairly new and the third at the bottom of the picture is pointed. I think that for $7,000.00 if you post a wanted add here on the Board in the For Sale section you will have some better machines to compare to or to chose from.
