Hey everyone, in my constant effort to fix the leaks on my old telehandler, I've run into an issue where the boom and fork tilt won't stop moving when I release the handle. It will stop if operating down, but not going up and if I tap the handle the other direction, it stops. This is a 1999 Terex SS1048. The main control valve was leaking so we took it apart and replaced the O-rings. This is a 3 part control valve with the top section controlling the boom in/out, middle controlling the tilt and the lower controlling the boom up/down. My thinking is that I have something, like an old O-ring piece, stuck in a port between the middle and bottom sections. But, before I start pulling it apart again, I wondered what others think. Is there a possibility that it's something else altogether. Everything worked great before taking it apart. Thanks!
