I just got an old 450c john deere dozer. Everything seems great for an hour or so than suddenly the left steering clutch doesn't grab at all. Several times it has done this than I try again later and it works perfect for a while again. Doesn't seem like a heat issue cause sometimes it will set for a long time and still not work. Any help or suggestions much appreciated.
The clutch is released with oil pressure, sounds like the steering valve spool may be hanging up, it's at the back end of the linkage.
Welcome to the Forums RLP!:drinkup I moved this thread over the dozer forum, best of luck!
