HST filter stuck good

[lennyzx11]

I caught **** with my first one at the first 50 hours service. I ended up using a huge pipe wrench to break it loose. I always smear grease on the seal when I put a filter on.
When I did my 400 hour service, it came right off!

I've had this issue with an RTV, two tractors and and SVL all of which are Kubota. I own all the wrenches and yet have still had to do the screw driver thing. Then one day I was trying to remove one off my track loader and was just about to drive a screwdriver through it when it hit me. Wait for it. Wait for it. I then loosened the coupling on the hydraulic line going to the filter holder and as soon as the pressure was released I could unscrew the filter by hand.

Good thinking. I’m learning.

Couldn’t attach my 4 in 1 with the flat faced couplers again. In my case I try to do it in the morning. Maybe because the pressure leaks down or maybe the fluid cools and loses volume?

I often will run a water hose over the lines and the attachment and sometimes that works. As for the 4-in-1, make sure you always close the bucket tight. if there is a gap, gravity will add pressure to the lines after it's detached.

I operate all the valves with the engine off. That should bleed off any pressure in the lines. The attachments need to be in a relaxed state though. (On the ground or supported.)

Releasing that pressure makes perfect sense.

Poke a good size screw driver straight through it and spin it off
abit messy but but it usually gets the stubborn one's off.

I did the screwdriver trick to my brothers car once. Didn稚 work and then couldn稚 drive. 2 days of hacking with chisels and screwdriver blades finally did it.

The screw driver trick is great, if it works. If not, you are dead in the water.

Good luck. BTW. I own 2-3 filter wrenches and then bought the universal kit from hf. I had 7 different filter wrenches. Not one fit any of the 7 kubota oil filters I replaced. Thank goodness my buddy had an old leather strap filter wrench. Old school!

They must do that on purpose?

Wow! I need to wake up. :ashamed: I was looking at one thread and typing on another. Sorry.

Channellock 480 is my go-to for difficult filters.
