hydraulics stopped working

[bundy mark]

I changed the transmission fluid on my recently purchased L2002 I am told it is a grey market tractor the same as an L275.started tractor after fluid change and speed and power in FEL was much better success. I decided to carry on maintenance, new fan belt and radiator hoses, took it for drive all working well stopped tractor to clean grease nipples ready to grease but when I started tractor I had no hydraulics at all not even 3pl. I cant understand what has happened can anybody offer me some help

First thing that comes to my mind is make sure you got all the drain plugs in and tight. Check your hyd. fluid level to be sure it's at the correct level.

When you say, "...took it for drive all working well." what specifically did you do during this drive to determine all was working correctly?

Check fluid level? Did you put fluid in the new filters before you installed them.

yes drain plugs are in and fluid levels are at top of site glass .I just drove long enough to raise temp to check radiator levels after hose change and raised and lowered loader and 3pl

yes fluid level is fine but no I did not fill new filter but it only took about 2 minutes for loader to bleed and start working then it had more power than before

Strange, almost seems as though you have an air lock. I'm sure someone with far more knowledge than I will be along soon, good luck.

Just checking but they did give you the right fluid for that tractor?

Either bad filter or filter seal, bad suction hose/line or connection, or bad hydraulic pump (least likely).

thanks to you guys for suggestions but all seems right with oil level type of oil ,no leaks, filter new from dealer was working strong for bout one hour while I shifted some dirt. Some how while carrying out further maintenance something has gone wrong. Is there a wire somewhere I could of nocked off or a valve to turn hydraulics off, just cant understand how even 3pl wont work

Is there some diverter valve that may not be in the correct position?

Just to be clear, you won't see the leak, the leak will just suck air in to the system and make the pump not work.

There is a lever on mine and should be on yours where you can lock your fel so you can't move it up or down.

Not on the old model FEL's.
