To all who replied and followed thank you. I finally figured out there was a bearing bad in the drive motor letting the piston housing become out of line with it's ports. Sk120
What is the fix? New bearing or will a new drive motor be required? Also, what model was this?
I bought a new drive assembly. I believe mine could be rebuilt but was just as cost efficient to replace. Kobelco sk120-3
Is it operating properly now? I would like to know if the cost efficiency was worth it
