Kubota l3400
I noticed a couple of weeks ago that the front end loader/3 point hitch on my Kubota L3400 were a bit slow to respond. In addition, my power steering seemed a little weak. I continued to run the tractor despite these issues and eventually the hydraulic system failed (the bucket and hitch dropped to the ground). The engine was not overheating, but there seemed to be an incredible amount of heat coming from under the seat/brakes/clutch. Upon further inspection I could see where hydraulic oil had been spraying from the suction line (the hose that makes a 90 degree turn located under the brakes).

Obviously, the suction line has to be replaced. I'm just thinking that it is likely that I damaged the hydraulic pump/other components of the system. Would it be worth replacing the hose myself and topping it off with fluid or should I go ahead and take it in to a get the hydraulic system assessed? Any ideas on how much damage I did and how much this blunder could potentially cost me?

Crappy first post to the forums.... Thanks in advance for your help!

Replace hose, replace filter, fill hydraulic fluid, and run it. You can't do anymore damage and may get lucky.

If that doesn't work, hang your head, say "I am a dumb *****" 25 times, and go see your dealer. :)

Not familiar with your tractor but suction line spraying oil? Something doesn't sound right because the suction line should be drawing a vacuum and only dripping when stopped. Doesn't make much difference on the repair - fix it and see what damage might have occurred.

Thanks everyone for your responses! I won't be able to work on it for a few days. I'll keep everyone posted - hopefully everything will run smoothly.

Suction line spraying fluid.

Is your pump running backwards.

If you damaged your suction line, it would be dripping until all the fluid was gone.

If your pump ran very long with no fluid, then some damage could have occurred.

Install new suction hose , fill tank and start tractor and try all the hyd.

Do a flow and pressure test.

You might have lucked out or not.

I think there is a moral to this story. When your equipment ceases to perform as it has in the past, should respond, or whatever, time to have a look-see as to why. Wake-up call/reminder for me.

Thanks,
Mark

UPDATE: So this past weekend I replaced the hose, drained all hydraulic oil, replaced the filter and then topped it off with new oil. Everything seems to be working great. The Kubota oil was pretty pricey (I figured it was worth it), but I'm pretty relieved that no damage seems to have occurred. Thanks everyone for your advice. Brian.
