Stuck Hydro Filter Will Not come Off!

Yep, that happens, and maybe I've been lucky, but I've yet to encounter a filter that wouldn't come off if you just keep going. If the filter gets partially crushed, those legs on the filter wrench just have a tigher hold.

And I'm not sure I'm explaining that very well.

No your explaing it perfect Bird. Something that helps when using that style of wrench is a rubber band around the three arms to hold them in.

Junkmans idea for a slipping band style wrench is a good one. I've never tried that.

Thanks, Gordon. That sounds like a simple, logical, solution. Makes me wonder why I didn't sense enough to think of that. /forums/images/graemlins/frown.gif

Unless you are changing an oil filter on a Powerstoke Diesel. There is a sticker on the oil pan stating "1-1/2 turns after gasket contacts mating surface". I have to use a wrench to get it that tight. These filters have a beveled o-ring/gasket, so it takes a lot of torque to get them to seal and stay sealed.

For future reference, if the gasket is flat-cut, tighten 1/2 to 3/4 turns after the gasket contacts the sealing surface (not hand tight). If it's bevel-cut, check the manual.

Well I got it off. It takes a spanner wrench on the base. If you just turn the filter body, it comes off the base. Does Kubota have a wrench to do this (in another 300 hours)? I used a punch and hammer to get it to go around. ALSO, I was only able to tighten 1/2 turn after contact, not the full turn asked for in the manual.

I am having the same problem with my 4240. Where did you get the spanner wrench and what size was it?

Thanks
