190XT Low Fluid Lost Hydraulics What to check for?

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I had a loader on. When disconnecting you extend the cylinders. I didn't think anything of it. Put on my grader blade and levelled the drive way. Right as I was about to finish I lost all hydraulics, but the PD still worked. 
I turned it off right away, checked everything, it was, of course, low on hydraulic fluid. Filled it and everything went back to normal and works just fine. 

My question is, is there anything I should check, change, grease, verify, that I didn't damage by running low on hydraulic fluid?

 Only thing I could think of would be the pump, but I don't know if/how there's anything to check. I just want to forestall any issues with good advice after my screw up.

	Check transmission oil level. I'll bet it is overfull. Nothing hurt. Carry on.

	Thanks Doc! Transmission was a bit overfull. Does the hydro and trans mix anywhere? I didn't lose the power director which was interesting to me.

	Yeah. They mix when the oil seal between the front and rear housing has failed. A relatively common problem on old tractors. You might have an external leak, but this is one you cannot see and the hyd oil keeps disappearing in the front and raising on the back. Make sure your hyd dipstick breather is OPEN. Remove the cotter pin and throw away the 3/8" ball inside the tube.
