Hi all, I’m hoping someone can help me out with my kobelco digger it’s year 2000 imported model sk130ur-1e into Australia. my problem is I’ve pretty much lost all function on the left hand hydraulic circuit eg no slew, dipper arm has power out but nothing coming in and left hand track minimal power. Have had a few local mechanics have a look we have bench tested the pump all ok. Done basic pressure checks just hoping for a bit of info where to start looking first. Any info greatly appreciated.

Also should mention when you hold the slew lever left or right you can feel it bouncing back like it’s fighting itself?

Wondering what shape the swivel is, since its a 2000 model. There are a few Kobelco experts on the site.

Thanks for the reply. Swivel?

It is the rotary joint under the center of swing gear, that sends the oil to the respective tracks no matter where the body of machine is parked. The seals go and then oil can by-pass to a different function than was commanded. Dirty job to rebuild if that is what is the problem. Not saying it is your problem, but some gauges hooked up could help determine.
