Hydraulic filter removal- Bobcat 825

[coreya3212]

Filter # is 6552507 as far as I know. I can double check that. The hydraulic filter that points towards the right side of the bobcat if you are sitting in the seat below your elbow. the replacement of that number I have has a smooth bottom. The oone on the machine that I want to replace has a bolt head on the bottom, but they are the same number. I cannot turn the bolt head, and have all but torn the filter in half trying to spin it off. My manual is at a friends place, who was bench testing my injectors, and is ordering me new ones.
I cant get this filter off and its making me insane. Any ideas???

The manual wil probably just say to spin it off anyways. I'd try a heavy duty strap wrench...mine's from snap-on, 2" fabric and attaches to 1/2" breaker bar. Or try the hammer and chisel method...if you have room and a helper to hold tension on the filter in the correct direction it'll go easier.

I had a chain wrench on it with a 4 foot pipe and stopped prior to tearing the filter as I think if that happens, I am really in for a challenge.

Wouldnt a chisel just tear thru the filter??

Sadly, it sounds like you may need a new filter housing. I remember another member with an issue like this. He got it off, not sure how, but in doing so, the threads picked up and destroyed the filter neck.
As mrfixitpaul stated, get someone to hold pressure on the filter then use a chisel and strike the outer housing of the filter to jar it, hopefully it will crack the seal and allow it to come off.
They are meant to only be done up hand tight, it seems the previous owner didn't think that was tight enough.....

Just to provide some resolution to this thread. The bolt on the bottom of the filter I am trying to remove was, cosmetic, I guess, it was just formed on the bottom of the cylinder. Possibly to make it easier to remove as opposed to having to grip it with a strap?? i dont know. this thinkg was WAY tighter than hand tight though. I figure whoever changed the filter last, used a box wrench on that bolt to tighten it. I ended up peeling that bolt head out of the cylinder with a pipe wrench. Then I decided to cut the filter as close to the filter housing as possible using an air chisel. I then put the chisel in one of the round holes around the thread casing and used the air chisel to drive the remaining piece out. It came out relatively easy with the air chisel.

Thanks for helping fellas.

Good to hear you got it off. They sure are great tools, i used one to remove a stuck glad nut in a tilt cylinder. I spent no less than 30 minutes on it getting it to come free. Even heating with a torch!!! The alloy gland nut had seen better days after this though, ever so slightly mangled.

I have had a tight filter before, but this was something else for sure. I dont know why I am always afraid to tear a filter. Now i know its easier to cut it. The air chisel rips the outer skin like butter, then put the edge in one of the internal oil holes and drive it loose. Live and learn.

thanks again all!!

don't forget that filter under your feet as you sit in the machine, you know, the one we both like to change so much!! I just did mine to be ready for winter but I never look forward to that job. Jeffco
