Kubota B1640 FEL Control Valve Replacement?

[ghout7]

Hi,

New to the forum, and new to tractor ownership, so sorry for the stupidity! I recently bought a Kubota B7200 tractor with a backhoe and B1640 Front End Loader from my brother, with the knowledge that it needs some "work".

The control valve for the FEL is most likely shot, and I think I'd rather replace it than rebuild it. It sprays out a steady stream of oil on my feet at certain times, and gets stuck in the up position often.

The problem is that I'm having difficulty finding specs, and I know next to nothing about hydraulics. I've attached a diagram of the existing control valve from the user manual, and am wondering if anyone can suggest a source for a replacement that would work.

The manual only states "control valve, two spool with handle" and the specs say "one detent float position, power beyond circuit" and relief valve setting at 1450psi.

Any suggestions would be greatly appreciated!

Here is a great valve that would work well on your FEL> Surplus Center 9-7401, you will also need the Power Beyond kit listed in the upper right corner.

Thanks, Kenny! Great recommendation. Also, I noticed your comment on the other post -- I'm not sure how to delete the Hydraulic post since it doesn't allow me to edit yet. Sorry!

I have the same issue as below. The manufacturer has gone out of business according to a Tech at Surplus Center.

Ed, here is the website for them: BRAND Hydraulics suppliers of hydraulic valves and pumps

NT might have it in stock: Brand Hydraulics Monoblock Loader Valve with Regeneration, Model# PLV22RFSTKAB | Control Valves| Northern Tool + Equipment

I've noticed on the after market loader controls some have a regeneration. What is that. I can buy one without it for $10 less. Not sure if I need it.

I am on limited access now, but if you search the term "regen" you can read for hours. For $10, get it.

Hey, thanks Kenny. Now I know! What I don't know is do I need a separate hyd. line to accommodate the regenerative powers of the valve? And, if so, where does it go on the tractor.

Eagle, no special plumbing is required, everything is done inside the valve.

Alrighty then... here goes another adventure!!!
