Kubota l2800 hst filter leaking

[dayton kubota]

I have a kubota l2800 hst. The hst filter keeps blowing seal out. I bought a new filter mount and put it on. It ran good for 20 minutes and blew seal out again. I've searched the web trying to find same problem but no luck. Hopefully someone here will know. Thanks for any help.

Been on these forums for 20 years, have not heard of this before... Is your L2800 early model? 2004 until 2007 or is it the later models that have "Extra Power" decal on the side of the hood? (after 2007...)

Only thing I can think of, look for the breather tube under the seat - see if it's clogged. Might be heating up and extra air pressure can not escape....

Under the seat... only photo I have is without the seat attached.... The question mark, rubber tube thing...

Not sure of the year. It does have the extra power on hood. I will look at tube. It's really the oddest thing.

See photos I added for location of tube....

Another thing is to check to make sure you don't have left over rubber gaskets or magnetic rings stuck on the machine when you swap filters. Make sure your gasket mount surface is clean and damage free ie no scratches, nicks, rust,...

Definitely sounds like your building too much pressure. It can't escape. Point of least resistance is the filter seal

I bought a new mounting bracket from dealer because I thought it was the problem.

How much oil is coming from the filter? Blowing the seal sounds like a lot...

If you have to unscrew the filter to check the double, rubber gaskets or magnetic rings, there is a quick trick with a shop vac sucking "air" through the fill port. When you unscrew the filter, very little oil comes out, but air will keep the oil from rushing out.

Mine doesn't have that. I wonder if that's the problem

It's definitely a lot. You can see the dead trail in field before I realized it was leaking

So the next model from ours is the L3200, the breather tube is on the side of the "Top" of the engine... look there.

I would
* Make sure you got the correct filter for that location and have tightened it correctly.
* Check charge pressure
* Remove/clean charge relief valve

Ideally, I'd check the pressure first, but it may require a special/metric/British gauge adapter. There's a WSM available that should cover your tractor, it's the Scottish version.
