Looking for ideas here.
I recently purchased a Kubota KX41 mini Excavator. It has an aftermarket hydraulic thumb by PECK. The thumb pivot pin is bent.
I see 2 options:
1) put a Sawzall blade in the gap and cut it at the bend, replace it with a new pin. (seems to be 1 3/16" diam.)
2) Think of a way to use the bucket and thumb hydraulics to bend it back straight without removing it.
#1 is pretty straightforward. Cut it out, & excavator is disabled until all the elements fall into place. Bend the thumb arm back straight too and re-assemble. "Bend back straight" is easier said than done.
The reason I'm considering #2 is that it might be possible to complete #2 in a half hour, which is a fraction of the time to even locate suppliers of replacement parts. Has anyone had luck using tractor hydraulics to fix itself?
It seems worth a try so whats the risk? If it bends back halfway, it the gap may close then I can't get a Sawzall blade in there (to cut it at the bend). I know about bending pins they sometimes squirm & rotate themselves to avoid bending.
