Factory engine oil filter like it was welded on

[thadri]

In the process of a 50 hour service oil change, drained oil and I can遞 get the factory oil filter off!! Tried a filter socket already, letting some PB catalyst soak in overnight, but seriously it逞ｴ like it was welded on in the factory!!! Help!!

They are on good and tight sometimes , you turning it the correct way ...

 

[thadri]

Been trying to turn counter clockwise assuming that is correct

 

[Peter 315]

YES...

Do you have a regular filter wrench also try both at the same time

Sometimes a big pair of channelocks, is the only thing, cause it will bite without destroying the filter. But there is the large screwdriver through the middle that should work.

I had the same problem on my Kubota- ended up using a BIG pipe wrench - worked great. Came right off. I BENT 1 filter wrench and broke a 2nd one before moving to the pipe wrench.
Good luck

Of course new filter smear a little oil on gasket. Factory sounds like they didn't do that.

You Kando anything with a pipe wrench! Sometimes a long pipe on handle!

PB is for rust/corrositon. I've seen the stuff swell o-rings. Maybe you'll get lucky and it will turn the rubber gasket to mush instead of swelling it up and making it worst!

I have done well with a chain wrench, or an impact chisel on the base of the hydraulic filters. I doubt the engine oil filter has the same slotted base though.

Crescent oil filter slip joint pliers. Has made my life easier.

Had a canister fuel filter loosen while pulling the camper north Texas and lost 1/2 tank of fuel going down the road. Kinda over tighten to fix beside the road. Pliers got if off when I got home.

What nobody mentions - the factory installed filter is tightened down by a 900# gorilla - then they paint the frame, including the filter. The gorilla plus the dry paint = PITA. At my 50 hour service - I knew what was coming. Used a LARGE pipe wrench - sweet as apple pie.

........then you add that on some equipment, you can barely even see the filter let alone get a good wrench on it.

I have used a craftsman strap wrench when all else fails, been worth the 20 bucks many times over that I spent on it almost 40 years ago

I've had this happen on lots of different kind of engines when they are new. I've had to drive a screwdriver through some and twist them that way. Be sure to check that the rubber gasket wasn't stuck hard to the metal when it does let go. Then I always smear a little grease on the rubber gasket of the new one and it doesn't have to be *too* tight.

Had the same issue with the oil filters on a 450hp Cummins diesel I once owned. The problem persisted even with the filters I installed that were only hand tight. Finally figured out the oil pressure when the engine was running was enough to cause the thin metal of the filter housing to deform causing the tightness. A heavy duty strap wrench with 1/2" drive socket break-over handle solved the problem.

Another tip is to take a razor knife around the perimeter where the oil filter is painted tight to the filter flange. When I did the 50 hr service, I mangled the oil filter big time, still could not get it off. I cut a couple of times around it with the knife, and it came right off.

I have had the luxury of 2 new tractors. Both had the same problems as you describe. Have the same problem with a lot of fasteners. Seems they are right at the spec limit for their size and condition. I have half a dozen or so filter wrenches and some times it takes trying several of them to find what will get one off. On the bolts and nuts, I'm up to 6 impact tools (and sockets) now, one for every peculiarity....thank you HF.
