original hydraulic filters wont come off.

To be fair, most of the options that will work on a badly stuck filter will ruin the filter [screw driver, pipe wrench, big channel locks, or 3-point]... but then again, you never want to see that filter again, and it's cathartic to be able to rid yourself of it. Just don't forget to lube the seal on the new one to not go through it again... but if you just struggled to get the old one off, you are usually thinking hard when you put the new one on about what will prevent the same agony in the future.

these are the Hydraulic filters side by side. The base as 3 magnets mounted on a shaft for collecting any metal filings that may be in the system it protrudes about 4" into the filter So i Drilled a 3/8 hole a safe distance away from those magnets. It worked but the frustration level was off the charts.
I don't want to offend anyone, but you would think that college educated engineers would be able to foresee something like this and make sure these filters are mounted in an area that can be easily accessed.

I think college educated engineers should be made to work in the environment of their specialty which would give them mental pictures of all the problems that could easily be solved while still on paper.
Sorry, just my 2 cents

I had the same problem. Final solution was a strap wrench with sandpaper wrapped around the filter to prevent slippage. Worked like a charm!

Great idea, sandpaper.

Paint doesn't lock filters in place, however, dry seals and over tightening do and that seems to be a common practice from the manufacturers for some reason. All it took, was just a few drops of oil in the filter seal.

The big hydraulic filter on my tractor wasn't painted and it still was a pain to remove and the mechanic at my dealer almost smash his hand really hard after the engine oil filter finally broke loose, again not painted.

agree, my take is that manu don't lube filter seal to ensure no chance of filter backing off. then they leave the removal problem to the new owner.
i.ve read where some owners puncture through the filter w/screwdriver, then remove, but i've avoided that one

On medium sized tractors, I've had the best luck with this type of oil filter removal tool, the vise grip plier style.


They work great and I can grip the filter near the base where the torque does the most good. I bought mine on a lark from Harbor Freight but now they are my favs. If you can get them on the filter you can get the filter off.

Yup LS has the same issue. I just happened to read a forum or two when I bought my LS and they had a conversation going on that. When it was time to do my '22 MT-235 first hyd filter change I couldn't believe how stupid tight it was.
I used three different types of tools AND the screw driver and it still was an issue. The tools just twisted the can like a pretzel and the screw driver just split the can like a pop can. I was finally able to use my cheap band clamp on what was left of the metal. Thank goodness I didn't have the magnets that the OP had on his.

I have a set of these:

If I can't get the filter off with a breaker bar, I use an impact wrench.

The trick is finding the right size.

3/8" please.

 

[ironman1952]

I did try my impact wrench but as its been brought out too much of the impact motion is lost over the length of the filter.
There is vey little room on my tractor to get a breaker bar in.
I do like filter type socket that AB suggested. what is the technical name for that and my filter is 4.5" diameter, do they make them that big?

When nothing else works I break out the oil filter vice grips. I must have 20 different oil filter wrenches/sockets/straps/chains. I might only get 1/10 of a turn on a filter in confined space, but the vice grips have never let me down. It helps that I have a 4 post lift and I don't have to crawl under the tractor/car/truck/mower.

I had a tough one on my jd skid steer that I bought used. I went to change the hydraulic filter since the machine was new to me and I wanted everything serviced before I used the machine. I tried all different wrenches. Including the pliers type which only put a hole in the filter. Eventually I had to chisel what was left of it off of the mounting plate. Once I replaced it with a new one I never had a problem again.
