    Return filter blocked???

    Yeah that’s okay I’m just happy that we have found the issue….maybe hahah, and yeah we’ve taken out every little filter screen and have replacement filters and have wiped the tank clean and the mechanic is going to double check and go through it all before he puts the new pump on

    Return filter blocked???

    it’s been a few weeks but the mechanic came out and spent a day testing and troubleshooting and this is what the outcome is. He took the pump off and put it on the bench and as you can see the plungers are distorted and squashed, we are unsure how the fist hydraulic shop I took it said it was in...

    Don’t stress yourself to much on it haha I do have the mechanic coming out again in a few weeks and he said he’s going to do some flow testing and hopefully he gets to the bottom of it

    Return filter blocked???

    I did have a mechanic come out briefly on his way through to another job and he took the main relief valves out and inspected them, springs and orings and said they looked good and played around with the adjustment but no matter what he did it didn’t change any values or anything performance wise

    Return filter blocked???

    I had another play around tonight on the digger and this is what I found. this might be a little tricky to understand but I’ll try my best. Okay so I have 3 outlets coming from the pump, P1,P2,P3. We won’t worry about P3 because that goes to the solenoid block. So P1 and P2 both go to the valve...

    I’m not sure if this is any clearer, when I upload it it decreases the quality

    Return filter blocked???

    The only electronics on the digger is the solenoid block and the 1 and 2 speed solenoids. Iv had a look to see if I missed any other solenoid relays or any as such and nothing, it seems pretty basic I don’t have any sort of ecu or anything

    Return filter blocked???

    I called a hydraulic mechanic today and got to pick his brain a bit and after going through everything and telling him the filters iv replaced, the screens iv cleaned and how a hydraulic shop had a look at my pump and said it was in perfect condition and after all that he said to change my fluid...

    Return filter blocked???

    As you can see the noise is coming from P1 and only when I use the right pilot controls and blade because that controls that side but the left doesn’t sound like I have any cavitation/vibration

    Return filter blocked???

    I have what looks like a radiator cap on top of the tank. I’ll upload a picture of the tare of the hose too. I also took a video of the sounds but unfortunately I can’t upload it

    Return filter blocked???

    Yeah I actually checked the strainer filter tonight that’s why I had the hydro tank empty and iv replaced the rings on the pump and tank inlet flange and the hose is soft and pliable. I did notice on the hose that sounds like it has cavitation issues that there is a very slight tare or what...

    Return filter blocked???

    I didn’t get to to what you suggested tonight but I did have another muck around with it and this is what I found. There’s a hose that goes from the solenoid block to the valve body and I thought while the machine has no hydraulic fluid in it at the moment I’ll see if the pipe is blocked or...

    Return filter blocked???

    I also have this valve that could potentially be the issue? But as you know every function on my machine doesn’t work or moves very very slow if any at all

    Return filter blocked???

    Alright so iv tested the pressure between the solenoid block and valve block and the pressure seems very good. I’m yet again at a block and unsure what to test or go from here. Now when I bought the machine the guy said that his employee sometimes changes the controls from standard to backhoe...
