Hello. At the beginning I want to apologize for the spelling, but translators are translate google translate because I'm from another country.
I have bought a FORD 4600 tractor and I have a problem with plumbing from the very beginning
The oil and filter in the hydraulics was changed half a year ago (he worked 200 h), and the fact that the previous owner assured that recently when he used the lift (ie about 2 months ago) everything was ok.
I noticed that under load when the lift lifts up everything is ok (floats smoothly, does not tug) but when it reaches the required height, it gradually descends and raises again. As a result, raising and lowering the tractor trembles so that it can not withstand it. What could be the reason?

This only happens when I have something connected to the tractor. When nothing is connected, the lift itself will not tremble.

I will add that the tractor is equipped with a front loader that goes flawlessly .... (for those who do not know I'll add that this tractor has a lever under the seat to change the hydraulics (selector valve) (works or jack or turn)). I also know that the tractor has the regulation of the pace of the hydraulic pump, but if I did not set it all the time the front loader works without changes (it's ok) and the lift bounces ...
The oil condition when I check on the dipstick is ok (the tractor has the one behind the rear left axle).
There is enough oil. I also change the oil and filter and it did nothing - it's the same ...
I am surprised that the front loader works properly, and the lift no ...
What can cause jump the lift to ?
p.s.
One mechanic told me that the selector valve has malfunctions, I changed it to another one and the same thing continues
Please help
