Our F6640 with a 7411 loader is having problems. The loader will lift when empty but has a hard time with a full bucket. The bucket curls ok under load but when lifting under load there is a hissing sound coming from the spool valve like something is bypassing and the loader lifts real slow almost stalls. My guess its a relief valve stuck open but where. I've looked in the loader manual and found nothing except it says to check the relief valve in the troubleshooting chart. Anyone have an ideas where and what to look for? Rick do you have one of your quick easy fixes??
