BX2200 hydraulic leak rear right above hydraulic filter

[martinlaurentide]

Update. Tank off showing how to avoid emptying but no idea from where it's leaking and would need to feed fuel somehow to see but stopping for the night. 5 last pictures. attached...

UPDATE: relating to last photo with blue dye in hydraulic fluid showing where the leak is emanating from... I need to figure out how to remove the fuel tank. Wondering if I need to empty it or if it can be loosened and move enough to address the leak or at least determine the source if / what parts are needed... I had already emptied it a week back to clear some blockage etc... and refilled it to do a job...

2001 bx2200 hydraulic leak @ rear right side per video clip, above the filter, when running. Ideas welcome... Thanks.

Been looking online and in the shop manual to find process but as stated to start from top, it means remove seat, metal behind floor for acces to inspect?

Seat and floor are off... need to find how to remove the fuel tank.

Suspicion from the start looking more and more likely: is that the inaccessible bolt that holds the HST in place (top right looking forward) was loose and loosened more but per pics, still cannot get to it.
Any hints as to where the fuel tank fastenings are... checking manual for that but I find it hard to find much in there...

You really need to pull that sucker outside and degrease and pressure wash everything if you expect to narrow it down.

It's disassembled per the updates. I have been cleaning strategically with brake clean and compressed air as I go. My pressure washer broke and I've not located a pump as of yet. Now totally apart, I still don't know where it is likely coming from despite the blue dye. I may need to hook up some fuel somehow to see it flow out one more time to diagnose but ideas welcome.

Adding diagrams... gasket? Is that a challenge to do? Should I call a tech or continue on my own?

 

[martinlaurentide]

Completely disassembled with funnel for fuel, dye in the hydraulic fluid, I just ran this and have no idea what is needed to stop the leak.

I could not post videos of all the test runs after stripping it down so in case this helps, I am at a loss here. Thanks!

I'm pretty sure you have a cracked case, one of your videos shows it.

I had the neighbours depress the seat by-pass button, turn the key and with 2 more lights... a better video... It looks like the housing cracked. I will open the plugs with the Allen key if I can but can't imagine it's an o-ring causing that let alone 2 simultaneously. I need to determine if in fact that housing is cracked whether JB weld is an option, replace just the housing or get a whole new unit... Very expensive like $3k CDN ($2,300 USD) just for the unit... I also don't know that I should go further on my own or get the Kubota tech also $1,000's in labo(u)r... Last year it leaked because a bolt fell out, which I found and replaced so it must have cracked back then and eventually evolved in one shot due to pressure into this...

Just saw this.. Thank you. So it's unlikely the o-rings beneath the Allen head plugs then. I will check with the Kubota tech and get an estimate to replace that because I suspect changing that might be beyond what I should try and do... it was my deepest gut feeling. Just wondering how that could happen.

I would get a hands on evaluation of it.
As videos can fool me.
If you wash it all off and take a video of when the leak first starts I might be able to give you a more definitive answer.

Thank you. I did not see this until last night and believe you are correct. Having trouble with edits and can't delete posts or edit easily from my phone which I use from the garage.

I will bring the entire unit to the dealer for them to change all the o-rings and what suspect is the middle gasket that leaks. It's mostly disconnected and I found the 2 top of 4 bolts that hold it in place, loose and one behind which appears to be an Allen key head so loose that it's almost falling out. That said, I cannot get the unit out. Please anyone who knows, please let me know what I missed. The manual just says, " remove HST"... There are 2 bars that block it from moving forward or up. I don't know how to remove either of them... I feel like crying.
