Banjo fitting leaking in the case.

[davygp38]

I have a Kubota L4400, with 52 hours on it. I am a few days over the one year warranty. There is a banjo fitting that comes out of the auxiliary block for the FEL, and goes right into the transmission case, and it is leaking. There is no visible mechanical connection to the tranny case, unless it is in the case. I was wondering if anyone has had a similar problem, or knows how big a deal this is to fix. I don't have any pics, because this happened in the field, and I had to leave it to get to work. I won't make it back up there till Saturday next. I called the dealer, he was very vague, about the cost. Since I am due for my 50 hour service, I will let him do the service, and fix the leak, but I don't want a "bill of goods." I got to tell you, this guy would not give me a price for the service. I kept asking for a "ball park price," and he kept saying "well its a 2 and a half hour job, and we will flush the system." I asked him to please give me an Idea of the price, and he would not. Am I crazy, or am I getting the world class run around? Any help you fellows give me will come in handy.

hmm.. I think I would have taken the banjo fitting apart and repalced the sealing washers myself.. then let the service happen ( or.. heck.. service it myself .. )

:thumbsup:

Then tell the service man exactly what it cost, and time so he knows if any one else needs the service!

In an emergency, I have been known to anneal the sealing washers with a propane torch and re-use them. Not recommended, but if the fitting is easy to work on and it is late Sunday afternoon, what do you have to lose? It has always worked for me.

Dude, cross the border into Pa, take rte 6 up to Shohola. On the right side about halfway to Wallenpaupack will be Industrial Hose and Supply. Ask for Steve. He forgot more than most people know about this stuff. He has a hose and fitting shop to die for. His # is 570-296-5551. I guarantee you will not be disappointed. Oh, it's probably the bonded seals leaking, the 2 little washers with the rubber rings inside.

I have seen those bonded washers sometimes used in places where an orb fitting has been added to a port originally meant for a banjo connection, but where no counter bore for the oring exists.

I actually prefer the crush washers to the washer with oring on the id though.

but heck.. whatever stops the leak right?

I have seen some places that sell assortments of copper washers presumably for oil pans and whatnot.. however.. they seem to work fine in the hyd applications I've used them in. ymmv

You know, thats really close to where the dealer is, I'm sure you can guess who it is. My problem, is that I cannot tell how the other end of the fitting (the part that leaks) is attached to the transmission case. It just looks like it pokes through the case, and is attached from the inside, or is just pushed in with an o ring. If I knew how it was attached to the case, I would take it off, and do like you say.

I like your way of thinking, curlydave.

Case has to be threaded. Just unscrew it. I am in that area frequently. I'll pm you with my # if you have a problem. I can stop by and take a look for you. I live in a development on Lake Wallenpaupack and fly down 84 every morning.

According to the mechanic at Marshalls this is a press in fitting. The end that goes into the trans case is just pressed into the case, it has a rubber o ring. the end that goes to the accessory block, has the standard bandjo fitting, with a crush washer
