bobcat 743b keeps blowing hoses

[monkeys uncle]

Bobcat 743b keeps blowing hoses every time I use it another hose blows. Using aw46. new filter. every thing works, one hose after another leaks. Help is appreciated.

Are these original hoses? If so, I think you can expect to lose them routinely due to age; especially if any are showing signs of chafing or cuts on the OD.

It's possible the relief vavle is out of adjustment allowing too high of pressure. But as the other post said, probably just old dry rotted hoses blowing one after enough. I've screw with a couple machines that did nothing but leak at one spot after another.

I cant run the machine without another hose popping. 3 in 24 hours, is that routinely

How crappy do the hoses look that blow? Any brand new hoses repeatably blowing, or one 20+ year old hose after another?

Really, we need to know what kind of shape the hoses are in, what their rated pressure is, and where/how they are failing to help much. I have damaged even new hoses in just a couple of hours, due to crushing and cutting them doing my jack-hammer work. One even pulled the end fitting in two. Didn't come out at the crimp, simply busted the nut from yanking on the hose.

Replacing last old hose Tuesday. I will post if I lose a new one. all hoses are new now

I would definitely check your relief valve though.I had a machine that blew a hose than after that it went after the seals. for some reason the previous owner set the relief valve to high.
