This CAT 349F had a stuck quick coupler with grapple on the machine and they needed to switch to a bucket. After confirming that the hydraulics were functioning properly and that there was a mechanical stall on the coupler itself I needed to remove the attachment and the top cover for further inspection. After removing the caps on the locking spring wedge I saw that the springs were completely blown apart and the bolts holding the wedge in were cross threaded 3/4 of the way in causing the cylinder to stall since the front lock was jammed After failing to extract bolts I drilled out and installed helicoils and reassembled and welded the wedge in for further support. Good as new
