kubota hydraulics messed up

[Bamasport]

Hello to all from a new guy in Mobile, AL.
This sounds like the problem I'm having w/ a Kubota L3300 4wd w/ shuttle-shift and loader. The bucket is jerky in its operation and the power steering is stiff. My question is: Is the large spin-on filter I see under the floor board below my right foot the filter for the hydraulics? Is this the only one or might there be another one? Any idea how much hydraulic oil it takes to change it?
Thanks,
Bamasport

Barney,

Since it effects all the circuits, I would check the suction hose on the gear pump - it looks like a question mark.

If the rubber looks at all questionable, change the hose - that is the most likely source of the aeration.

Good luck!

front loader will not go down with motor off.

Yes, suction leak could be it but how about FEL not going down....? restriction in RL or cyl just chuck full of foamy pressurized air?

Good catch WD, I missed that fact when reading the post originally.

I would bet that a QD (quick disconnect) is not seated all the way. Unplug all of them then re-connect them.

I am having the same problem with my 3400, I will check out the QD's, the small drip on my return linessince beginning, even mentioned to service mgr. to no avail, will check my suction line from sump for cracks. Good post, great ideas.

Found problem in rubber hose attaching pump to metal return line. Thank all of you for this post.

I thought I was in deep deep trouble.
