Stuck Hydraulic Filter

[Redbug]

Another tool, (I can recommend, that I have and use), is a vise grip locking chain clamp. Wrap the chain portion around the base of the filter, tighten down and turn. It's like a strap wrench. The tool is good for all kinds of other things...(can't have too many tools)...

I had the same problem on my high pressure hydraulic side. The base was notched and looked like it was made for a special type wrench. I used a punch and hammer and kept tapping on the base of the filter using the notches to put the punch in. After about 20 minutes it came free. This filter was much heavier made, but I was afraid to punch a screw driver thru it. I did make sure I greased the new on.

I had the same problem on my DK35 at my 50 hour service. It seemed like the filter was put on and then the frame was powder coated. I used something like Redbug suggested but it wasn't attached to a vice grip. It;s known as a plumbers chain wrench, and you can pick one up at most plumbers supply places. I used in rather than the vice grip type due to the restricted space I had to work in.

It worked very well and was well worth the price.

Forgot to update, I wound up using the screwdriver through the filter method. I punched it about 3 inches up from the bottom. It came off with a little effort. I was suprised that the strap wrench didn't work because it seemed like I was using more force with the strap wrench than the screwdriver. This time I took the backhoe completely off (which was for the first time and it wasn't as difficult getting the hoses re-connected than I thought it would be) and that gives a little more room to work without the subframe mount. Thanks again for all the tips and advice.


Oh yeah, this time I made sure to put a film a fluid on the gasket and again only put the filter on hand tight about a half turn or so after the gasket contacted the housing.
