Hello All
I could use your help with my Kabota hydraulic lift.
If you don't mind let me set the scenario.
I just bought a Kabota L245 3 cyl diesel.
I bought from a dealer who had it on his lot for about 1 or 2 months.
I talked with him about the tractor before driving the 200 miles to get it and he said the lift and pto worked fine.
When I got to the sales lot the lift did not work. it was saturday and no mechanics were working and it was raining and the man said he did not want to crawl under it on that rainy day but he said he could tell by the sucking sound the lift was making that it only needed to have the filter screen cleaned and it would work. He said it had been working the whole time he had it on the lot and he was sure that cleaning the filter would fix it.
I bought it and brought it home and cleaned the filter screen and sure enough it worked great. it would lift the 5' bushhog and 5' box blade with no problem.
It has been 1 week ago today that I cleaned the screen and got it working.
Well Today I went to move a small pile of dirt with the box blade. I cranked up the tractor, raised the lift and backed up to the dirt pile, lowered the blade and all was well. I dragged a little dirt a few feet and went to raise the blade and there was no lift. It would not go up at all.
I drained all the hydraulic fluid (hyd/trans) and removed the filter screen and cleaned it again even though it was not dirty.
Put in all new 23 quarts of hyd/trans fluid and still had no lift.
I removed the box blade and the the lift would go up but only at full throttle. You can place your foot on the lift arms and it will not raise at all.
Even that small amount of weight will keep it from going up.
There is a control valve under the seat which controls how fast or slow the lift will go down and it did not seem to work even when the lift was working. It does not have any effect on the lowering speed. I noticed when I drained the fluid the first time to clean the screen that there were some black rubber looking framents in the oil. The same thing when I drained it the 2nd time to replace all fluid. There were some black fragments. Could this be seals or o rings?
The lift arms will stay raised up wherever I set them and not leak down with the tractor shut off and not running.
I disconnected the hydraulic lines at the pump and cranked the tractor and it poured fluid out at a pretty high flow.
I disconnected the line at a "box" looking thing under the seat and it poured out fluid at a high flow rate.
I have no way to test pressure and do not see any way to connect a pressure gauge to it.
I had someone suggest a sticking relief valve.
How can I test this?
From what I have described here can you give me your opinion(s) and suggest a starting point for me to get this thing fixed.
I appreciate any input.
Thanks
