Bobcat 337 hydraulics problem

[weedee]

Hello, I'm writing this post for friend of mine, who has Bobcat 337 (year 2000). It has worked adequately until now. Engine starts and runs perfectly fine. But anything, which relies on hydraulics, has suddenly stopped working without any warning (sound, smoke etc) Could anyone help where to start looking for the problem?

Likely the pump drive coupling has failed. Requires removing the pump assembly to check.

correct answer . remove two bolts that couple pump to fly , pump male steel , fly female plastic most likely cause of failure needs inspected before goining any farther.

Hello guys! First of all, thank you everyone for spending your time trying to help me and my friend out. Sorry it took me so long to get back to you and I really appreciate your help. Personally, I hate people who ask questions and when someone replies to them, they never get back if they got their issue sorted out. Then back to the issue... Bobcat is running happily again after one part was replaced between the engine and hydraulics pump. I don't know what's that part called in english, but like my friend described it to me, it was a disc shaped part with half of it made out of some hard plastic. That disc had some tooths, which were wore off. That's why the hydraulics stopped working. He thought that part was original one. I've not seen the part myself, so it's hard to tell how it looks like. He threw the broken part away so I can't even post a picture of it
