Not be a good weekend on a number of counts. The one I'll mention is my excavator threw a track in the woods climbing over piece of Ledge I had no business try to mess with.
My track adjuster is frozen. Lost a lot of sleep wondering if this is the end of the old girl? 1-1/2 days later & 1,000 wacks with a 16 Lb sledge together with a hydraulic Jack against the blade, help from the
L39 and the excavator arm, I got the track on & limped it out of the woods without trowing the track again, but cannot pump the track tight.
I first thought about trying a port a power cracked up to 10,000 psi hydraulic pressure at the grease port, but but I have an idea involving removing a track roller so I can get something up in the yoke to hold it out, like a block of wood.
If that temporarily seems to work, I'll design and 3D print a lockable saddle with inserts pockets for coupling nuts that that I can screw in 1/2 alloy bolts that can be act as adjustable jack screws. That way the jack screws and nuts bear the compressive load and the 3D printed plastic saddle is just holding the jack screws/coupling nuts in place around the shaft of the yoke between the stuck recoil cylinder and yoke flange.
I'm lucky I did not severe a finger or worse, dumb that I did this to my machine and clever in that I think I have a fix.
I imagine a new adjuster and front idler is thousands of dollars from Komatsu, and a Chinese import would end up still well over $1,000, plus all the danger & fun of removing the track.

Even if I "fix" it, the 21 year old machine is still the next major breakdown form the scrap heap. Sad, but I know I will never replace it. Hope it is around a few more seasons.
