Had an issue with hydraulic pressure and bought a new pump and installed it. I now have a gap between the pressure control valve and the housing. Am i missing something looking at parts breakdowns i cant see what should fit between but its impossible to push the two together, tried rebolting and maybe shifting the pump incase i some how mounted it wrong.
Bx2230d mower deck wont raise
- Thread starter Cbp
- Start date
Looking at both they are identical. Measured length and they measure the same. bolt patterns are identical and shaft sizes are identical absolutely no differences that i can see.
So i found some oring material/washer to link it off with and no longer lose hydraulic fluid but still not deck function. Took hydraulic control valve assembly apart and put it back together after cleaning and still had no luck getting the mower deck to raise up or down. Also flushed lines using air and could see deck attempt to move so lines aren't clogged. Any tips on why the mower deck might not be moving???Only thing I can think of is the piece circled should be down in the control valve where the o-ring is showing.
I can’t really help, but on my BX2200 the deck rises with the 3PH arms. Is you 3PH working? There should be a mechanical connection between the 3PH and the MMM linkage. Yours being a BX2230 is likely the same setup.
I'm with #40Fan. Something is jacked up there. Shouldn't have to add o-ring washer stuff in there to make up that gap. Either the pump is wrong or alignment or orientation when assembling is off. Looks like an unequal gap in the picture but might just be the camera angle making it look that way. That valve is the control valve and flow priority valve if it like Henry's BX2200 and my BX22, and I would expect it to be the same. How was it determined the pump was at fault leading to its replacement? Any testing done? Are the symptoms the same after the new pump?
Confirmed that the valve is the same as the BX22 and 2200.

The hydraulics would act up off and on while in use. Little messing around with the raise and lower lever it would come back. But eventually just gave out all together after several months of random off and ons. That control valve cant be wrong since when removing pump only two bolts mount it to the pump and allow you just enough gap to remove and reinstall pump. After talking to some people and googling it was assumed that. I was losing hydraulic pressure as if the pump was failing. So i replaced the pump. Once i used washer/oring material and sealed off it no longer loses fluid but still have the initial issue that it doesnt seem to have any hydraulic pressure this is confirmed when removing hydraulic lines such as the crossover line that goes from control valve assembly to the mower raise/lower arm. Im wondering if my pressure control valve or pressure release valve is the problem. I get fluid to pressure control valve confirmed by removing and fluid runs out just dont know if its bypassing and just blocking off.
Attached: the pressure relief and control are marked in blue but can anyone tell me what the red circled componet is?? I dont believe thats present on mine

Could you humor me and just state if the 3PH goes up and down normally, and if it does. if the mower deck during this time does or does not move. Just curious...can't help but wonder if you are seeing the forest but not the individual trees...
Not doubting you have a hydraulic issue that needs resolved...but if the 3PH moves up and down, the mower deck should move up and down, if it is like my BX2200, which is moved by a mechanical linkage to the 3PH arms. The BX2200 is very close in vintage to your BX2230. Guess it could be different, don't know...

My little looking in the parts of both models appears to be identical in that respect.
Questions:
Have you cleaned your suction screen?
Have you changed the hydraulic filter?
Is your oil foaming?
Is it full of oil?
Have you ever used the 3-point or do you just mow with it?
Does it have the loader attachment?

Oil and filter have both been changed and also just recently dumped and checked screen then refilled. No signs of hydrualic oil issues.
3ph moves in conjunction with mower base so 3ph doesnt move then mower deck doesnt. The two are linked 3ph isnt moving aswell as mower deck. Ive tried adjusting the hydraulic control lever that should help for releasing and allowing smooth down transitions and it will turn and lock both ways and doesnt appear to have any issues. It turns like it should. The front loader was removed once hydraulic function started failing. Prior to right before it failed all together.
No significant change in sound from initial startup when moving lever however there is a whining noise when running at the lower rpms but cant exactly pin point what it is. Once going up on rpms the engine either over powers sound or it phases out at the higher rpm. Loader also started having issues aswell
