Kubota B9200--What type of threads on hydraulic fittings

npalen · Jul 1, 2012

Wondering what type of fittings are used on the B9200 and BF350 FEL. I assume they're metric but are they British standard or something unique to Kubota? Looking to add some rear remotes and Tilt and Level.
Thanks
Edit: Also should ask about the quick couplers on the loader and what they might interchange with. Probably not Pioneer I'm guessing.

Can someone help me on this?
Thanks

I am not so sure anybody knows for sure as I have a B9200 and I doen't know. I had someone install the hose set up for me years ago.

I would recommend removing one of the plugs from the hyd block and taking it in to to a hyd shop to match fittings.

That is where you will connect a FEL or log splitter or BH.

Should look something like the picture and connect like the illustration.

We get questions like this all of the time. Folks just rattle off the make and model of their tractor or equipment, and think we'll be able to replace their hoses or fittings, whatever. Truth is, unless this info is listed in your operators manual, someone is going to have identify/measure the threads directly.

Taking your fittings or hoses to a local supplier may be the easiest option. If you want to do this yourself, you'll need a set of calipers and a thread gauge. Measure the OD and pitch of the male thread (measure the ID if you only have a female fitting). Compare your measurements to a reliable thread chart like this one.

Remember, unless you are working with metric threads, the actual thread is probably NOT the nominal size of the fitting. For example 1/2" pipe thread has a thread OD of 27/32 (0.84"). Use the thread chart to cross reference thread dimensions with the nominal fitting size.

The thread dimensions, along with the way your fitting seals, should help you identify your fittings.

Look on your quick couplers. You might find a brand and size or part number stamped on it that would help.
Faster is the brand on my JD

I called Messnicks, and they don't even have the description of the fitting.

Messnicks said that Kubota doesn't like to put out engineering drawings. I guess they only want you to only buy Kubota.

Again, the best thing you could do is to take the plug or fitting out of the hyd block if that is where you want to add some hoses, and the other end of the hose could be anything you wanted it to be.

Several people said all their fittings could be purchased at TSC.

I would still take the fitting in and match it up. Find the female fitting for the hyd block, and then select a hose fitting.

Thanks for your suggestions, guys.
I've worked with hydraulics most of my life and am familiar with SAE, JIC, tapered pipe thread, straight pipe thread etc. I just wondered what system Kubota used in general.
I would be surprised if it's not a metric system on the tractor and loader. It's not that I'm against doing the legwork just thought that it would help if I knew up front what the basic system is on the Kubota.

What is "ISO B"? It mentions interchange for Deere and Kubota on the above link.
Thanks

ISO B refers to the size of the male coupler external dimensions Full desigantion is ISO 7241-1 series B. An ISO B 3/8 will have a 3/4" OD and from the flat of the tip (not the ball or poppet) is 1/2" to the first lock band/ring. The internal threads are not covered by this std and can be a varity of different threads.
