Message: <blockquote data-quote="tucquan" data-source="post: 100480" data-attributes="member: 15284"><p>I have an L-555 loader with 3100 hrs on it. It had 2900 hrs. when I bought it from a dealer. A short time later the hydraulic charge light would come on and stay on for a few seconds. As time passed and I used the loader more I began to notice the hydraulic charge light would come on after I had driven some distance, maybe a hundred feet or more. The boom and bucket would not work, the machine would not move, and if I tried to move it, it would make a loud racket which I assume are the drive pumps. It was very noticeable when I moved a pile of stones several hundred feet. I had to go down a 200 foot driveway and turn right. Just about every time I turned, the light came on and all of the hydraulics went dead. I got around this by coming to a stop before I turned and the light did not come on. When I'm moving stone or dirt around a few feet and cycling the boom and bucket frequently, the light may come on for an instant and go out. There is no loss of hydraulics. Sometimes the light will stay on for at least a minute or more, and several times I shut it down and let it sit for a few minutes before restarting. The light will come momentarily and then go out. If I sit and let the motor run and don't touch anything, there is no unusual noises. I also noticed if I have the bucket tilted back and hit the pedal to lower the bucket, the light usually goes out. The loader runs fine and the bucket and boom work correctly when the light is out. I can run for a long time either plowing snow or moving dirt without any problem, and the next time I use it and travel a long distance, the light comes on. I talked to the dealer and he thought it might be the gear pump since all of the hydraulics stop working when the light comes on. My thought is if it is the pump, why doesn't it happen all the time? The fluid is up to the full mark on the dipstick, the screen is clean and the fluid looks clear although I don't know how old it is. Both of the filters have been changed. I have the operator and service manual. I looked at the troubleshooting section and I think I can rule out most of the repairs. The ones I can't verify according to the manual are a dirty relief valve, internal leakage in the control valve, or a malfunction of the charge pressure relief. I apologize for a long winded question. I wanted to list what I have observed since the problem started in the hope that if someone else has had the same problem, they will know what the answer is. I searched the forum and did not find anyone who has a problem similar to mine. Maybe I missed it. Any advice or suggestions are very much appreciated. Thanks, Bill</p></blockquote><p></p>
