Slew brake?

Haven’t really pressed it too hard as feels a bit stiff and worried it might not come off again (assuming pressing it puts something on) someone has labelled the peddles. I think it has an H. The other 4 do tracking and boom pivot.

Hammer?

Did that to the JS here about 5 years ago around this time of year. Then the man sent it to France and they left it in a wet hole for 4 months, it struggled to get loaded on the lorry, it's taken a lot of use and work to loosen the track links back up again

That was nice of them

What is the machine in the left of the photo, behind the dumper, I assume it's a track digger but there is a very big back on her

What did you do to loosen them, our diggers tracks have got tight and a few seized, didnt get used last winter, have been squirting some diesel on them to try and get them moving again

Diesel, creosote, old oil and keep moving the tracks. Kept tracking down some rough hardcore, brick rubble with some biggish lumps of concrete and keep up the diesel and oil.

It took a lot of time plus what could have been described as abuse.

I have the same issue on a machine, but cannot seem to get them to improve, unfortunately not in an acceptable environment to be pouring gallons of oil on them, although I did try an intensive campaign of Duck oil on the effected links. Unfortunately it hasn’t improved with use, in fact its got worse (possibly no it enough use). Bit of a shame as the machine only has circa 1000 Hours on it. Got to the point where any more use is total abuse as you say!

I find duck oil, very much like WD-40 good at penetrating but poor at lubricating, when it dries off it often leaves things worse and more likely to seize than they were before you used it

Im more of a duck oil fan than WD40, I find the Duck much better. But i get your point.
The thing with excavator chains is they are not meant to be lubricated with any sort of oil, unlike SALT chains that you may find on a dozer, I was just hoping to use the Duck oil to get the links moving and let them do their thing from then on. Sadly this has not worked.

It's amazing how strong rust is, when you don't want it to be

Would it be worth heating the problem link?
If it's that tight it's probably damaged the seal any way.
Presuming it's a sealed for life style chain

I know this sounds daft but I was told park the digger in running water and this will wash out the grit between the links. Whether it works I have no idea as never tried it.

I tracked a mile down the main road on the 1st Sunday of lockdown,it worked a treat.

Might carry the digger away in this!

These will have no seals. Heat may work, but would possibly have to be careful not to over heat the bush, it will be a hardened piece of steel I think.
I’m in favour of pushing each effected pin out, cleaning the pin and bush, then refitting. In a bid to save the chain, as the wear it currently has is undetectable! So apart form the seized links, its in very good condition.
Have to be very careful that forcing the links doesn’t result in the pin moving in the links, then its game over for the chain really.
