Blown Hose BX24

[kubotaownersson]

Outrigger house developed a pin hole and is leaking fluid.

For the life of me, I can't get this disconnected.

Any tips or tricks. This is the hose on the right side of the tractor that runs from the right outrigger and then underneath to what looks like a series of valves on the backhoe.

Also, I thought that the allen head bold might have something to do with it. I now realize it does't but can't get the allen head back in as there is a little pin that must be centered for the allen head to go back in.

I personally would start on and edge and pull hoses off (make sure you label them) till you can get a strait shot at the effected hose.

They will be very tight, hold the rear fitting with a wrench while you loosen the front hose fitting.
Crows feet come in handy in these situations.

As far as the Allen plug goes, it's a holder for a valve do not force it back in, it might take moving the control back and forth to get it centered.

So I took off the backhoe and it appears there are four bolts holding the valve control in place.

Looks like I have to remove that, and then as suggested, work my way into the blown hose.

CAUTION: when breaking a hydraulic line the machine may collapse or shift. BE CAREFUL and don't get mashed.

Not certain what is meant by "valve control". It should be possible to get a cover off, leaving the valve bank alone, and just remove hoses until you can get to the one you need.

Be prepared to hold a backup, which may involve bending a wrench to fit.

Some hydraulic banks will have a short (approximately 3/4- to 1-in long) male x female extension that will be in place. This is to allow alternating hoses to stick "out" further so wrench can be applied. And if it doesn't have one you should consider going back with a new one--makes life simpler in the future, assuming the valve bank hose cover will still fit. Available at your local hydraulic hose house.

Also go back with swivel-type hose ends (both ends) on the new hose, again if doing so will allow all the covers to go back on.

Get your new hose made at a real commercial hose house, not an auto parts store.

You need at the minium a set of 'crow-foot flare nut' wrenches to use with your ratchet. Sears has the best deal on the market and they're not inexpensive but well worth every cent.

You also need a set of hydraulc service wrenches, again from the long-line major name companies. Expensive but a one-time buy. Knock-offs at HF, but beware of chipping chrome slicing your hands: wear gloves when using.

Hold a backup on every fitting. It is possible to snap off a fitting, especially on the cylinder. When that hydraulic fitting comes loose it will tend to pop loose quickly so be prepared and don't chip a tooth on the way to the ground.

Please post back your continuing experiences so we may all learn.

I wouldn't think you would need to take the valve off but I've never worked on a BX. It's very common to take several lines off to access a bad one though. Like Wolfman said, label the lines before you take them off. Might be helpful to take a picture of the valve so you can see how the lines are turned so it's easier to put back together.
