I have a 2155 that I was out running my rotary cutter with. As I was driving noticed the steering begin to get stiff if I slowed down. I then stopped and noticed I had no power steering anymore. Then when I went to raise the loader it actually lowered as though it lost whatever pressure it previously had. I checked the rock shaft (I think that is the right term for the 3 point lift arm?) and it also lowered instead of raised. Checked and there was NOT a hydraulic pressure indication illuminated on the cluster.
At that time I was out on some land I own with only a small bag of tools in my truck. I removed the hyd filter and sprayed it with parts cleaner until it was clear. I had just changed the filter completely only about 5 hours prior. I also removed and cleaned the sump screen which was a good bit dirty but not like I've seen some people post pictures of. Since I didn't have access to all new trans/hyd fluid (it was a Saturday and my local JD dealer was closed) I recycled the recovered fluid that drained out of the sump. By the way... It was very dirty.... Almost black!
I put it all back together and there was no change at all. I read about checking the bypass valve but I'm not sure "how" to check it. Also, I have not yet performed a standby pressure test because I still have to order a set of gauges. One thing I did check is on the front pump I very slightly loosened one of the main lines coming off the pump and it immediately started leaking as though it's under pressure. I can also hear sort of a knocking sound coming from it (not sure if that's normal... First tractor and have only put about 10 hours on it personally). I put a very long screwdriver against it and the handle to my ear and it's definitely knocking from the pump. Again, I just don't know if that's normal. I do believe that the pump is being driven by the tranny output shaft though.
I now have another new filter and 7 gallons of new fluid. I just don't want to drain it etc yet until I feel like I have some sense of direction, then have to do it again for another reason.
It's weird because it was very sudden and affected everything, with no obvious noises or anything.
Possible that the filter is still the culprit?
How do I "inspect" the bypass valve?
I also looked into the filler port of the tranny and do not see any sort of spraying onto anything. Should there be, or should there not be?
Obviously the fluid is very dirty but would that kill the filter in just a few hours?
Any help would be greatly appreciated!!
