2016 BX 1870 Hydraulic filter exploding

[1870bx]

Changed the filter and fluid, when I started the tractor it expanded the hydraulic filter and blew oil out of the seal. Tried a different brand of filter and it blew as well. Bought another kubota filter and had the same results. Removed the pressure relief valve at the filter found no debris put the check valve back and still have the same problem. Cleaned strainer as well. Any help is appreciated.

The check valve ........ the one on the rear?

You did not mention fluid type you are using?

Or the part numbers for the filters. Not sure if it's significant unless it's the wrong part number.

I didnt mean to say check valve I apologize I meant to say pressure relief valve. The one at the filter. Using kubota udt2 fluid.

Using the kubota filter hhk20-36994.

So good oil and good filter and everything was working as it should until you replaced the hydraulic oil and filter. How much oil did you drain and how much did you put back in?

Put the old filter back on and see how it works.

4 filters and counting?

Maybe stop putting filters on until you find out what's wrong. HINT: It's not the filters.

3 filters bought the first one and it blew, bought a different brand to try it failed as well. Cleaned out pressure relief valve and then put another kubota filter on. Perfectly aware it isn't the filters but when one blows out and you try something else you kind of need a good filter to put back on. No need to be like that just simply hoping someone has had a similar issue and could help me and not be arrogant. Thank you

Dan’s suggestion in post number 7 could be very helpful in your troubleshooting process.

I wouldn’t ignore it.

I agree if I hadn't trashed it already. Wish I hadn't done that was not expecting this result

If all you did was drain, refil and replace the filter my guess is it is the filter. Are you sure you removed all the plastic wrap over the open end

Yes

 

[1870bx]

Yes

It is building enough pressure at the filter to completely separate it

Thats pretty obvious. I would suspect something is obstructing the filter outlet.

One question. Does the filter blow out when just starting and idling the machine. or when you increase engine speed or when you move the machine and if that which direction?
