QuestionI inherited a Universal 650 (Romanian built) tractor with a front end loader. The bucket wasn't staying up very well while mowing and one of the hoses was covered with oil so I thought it's leaking was causing the problem. So I replaced the hose, now the front end loader won't do anything. I thought the oil reservoir on the top of the engine was the place to fill, since there's a hose running down to the pump from there, and that's where I added oil when the power steering didn't work, and that fixed that. The 3point hitch still raises and lowers though I don't have anything attached to it. I tried loosening the hose connections on the front end loader to bleed it, and I got a lot of air-I thought at some point it would turn to just fluid (like bleeding brakes), but it never did, it spit air and (a little)fluid for quite a while. The power steering still works fine, so is there a different place to add the hydraulic fluid than the tank on top of the engine? Since everything worked before I took off the old hose, I just thought there was air in the line, though I was told it should self bleed. Any helpful ideas?
AnswerAlan the 650 had a couple of ways of supplying oil to the loader.
The first was the early series which took the oil from the lift cover just under the seat some had a extra resivor on the mud guard as well.
The second series sucked the oil from the bottom of the transmisstion casing the container you talk about is only for the power steer oil.
To determin where the oil comes from is easy from the rear to the front is 2 hydraulic lines one is smaall this is the pressure line the other is a larger one this is the suction line.
If the suction line is on the lift cover you will need to check the level at the rear next to where the top link goes on.
If the suction line is at the bottom of the gearbox casing you will then check the oil by a dip stick or a level plug on the side of the casing.
Hope this helps with your problems Alan.
