| I stop at the end of a field to day to check on something on the planter and when i got back in my JD 8100 the stop light was on and there was buzzer going of and a code on the screen. I think the code was CCU 63. Looked it up in the book and and it said it was for low hydrolic oil. So I got out and checked the site class and it was full not low so I pulled the fill cap off and oil shot every where. Does anyone have any idea what could cause this. My guess is that something is plugged some where. Any ideas would be greatly appreciated. |

He said that his sight gauge was supposed to be empty when running..........is this right? Mine will lower when running but still show oil. Thought that the operators book mentioned that this is what is supposed to happen......Hummmmm? |

| If your vacuum was running at the end of the field sitting there, it emptied the clean oil reservoir into the differential housing. Couple of things could cause it. One is if your vacuum is ran back into an scv instead of motor return port, two is transmission sump screen plugged also a sump screen in the differential housing. Most common is your hydraulic pump on right hand side of the tractor has excessive leakage. But I would check to see how your vacuum is plumbed. May also try to move it to scv number one if it is in a higher scv to let the oil return quicker. The reason to put on a motor return is it will dump it back into the sump quicker rather than having to go back through the scv's and hitch valve which can empty the clean oil reservoir. As far as the sight gauge being empty yes it will suck the oil down sometimes far enough you can't see it when the tractor is started. You should let the tractor sit before checking the hydraulic oil level. If the sight glass is completely full that means the clean oil reservoir is empty and the differential is full. The clean oil reservoir is seperate from the differential in front of it. I had one that when you checked the oil it looked low, added some oil to correct level run tractor for about an hour and it blew the cap off of the fill tube. The transmission sump screen was plugged up on it. When I checked it all the oil was in the transmission so it looked low, because it couldn't pull it out of it quick enough, then when I ran it eventually overfilled the differential housing because I had added too much oil. |

| Do check as Fred said It turned out to be as he said. The tech worked on it for a day. I did call him to say what i found out from ag talk. The tech wont admit that this helprf as he said he had pretty much narrowed it down to the pump.. Mine had more damage and required a new pump but I still had a days labour on it.. In the future I will go to ag talk first to see if someone has had the problem before.. Do take out the bias piston and check for scoring I had the problen of high oil levels as well as the code coming on.. THANKS Fred |
