another stuck oil filter

[Uncle Crumpet]

I have read all the threads I can find on this, but my problem is last change I used a K&N filter with the bolt head attached to the botom of the filter, to try and avoid this issue, DOH!!The bolt head has twisted off although the filter is still intact, problem is the fillter tool dont fit the K&N, it lacks the cut aways on the housing that the tool has,, so the sand paper trick is a no go.I'm thinking of trying the self tapping screw option, say 4 through the filter tool, but am reluctant as if I ferk the filter I'm 400kms away from the nearest workshop.Has anyone come up with any less destructive options?I have tried to tap the filter tool on with a bit of force, but dont want to risk creasing the filter in the recess, when you use the sandpaper, how much of a flogging can you give the tool against the filter without buggering it.Looking for ideas, thanks.

I found myself in the same situation a few weeks ago, the giant socket was just slipping around on the (champion) filter, I ended up drilling four holes in the filter tool and popping some large self tappers into the filter, If I wanted to ensure success then more holes and screws would be the way to go, but I would leave the filter alone if its not leaking and wait until I was in a better place.

A while ago I bought half a dozen K&N oil filters as they had the nut and I got a discount on buying 6. The bloody nut buckled or sheared off all of them, so I'll never buy another. Its not a solid nut, just a hexagonal pressing so theres no real strength in it.

I ended up puting a screwdriver through them to get them off but I can see that you are reluctant to break the filter. Have you tried a strap wrench around it or is there not enough clearance?

They're fully recessed filter so unfortunately no room for strap wrenches etc.

I think the best thing to try will be the self tappers through a filter tool but as Stewart says, I'd leave it until the bike can be attacked in a workshop. If it's really due an oil change, I'd just drop the oil and leave the filter in place for now.

Just hit a big screw driver through it and turn it loose.

no clearance for strap wrench, so will leave for now, has anyone had sucess using a nut welded on with cold weld like JB WELD?

This is good...

...as is this, but a bit more crude...

..whereupon you'll be wasting your time with this.

I've used the screwdriver method many times: it's not ideal but always works, and go gently.

Two screwdrivers (large dia) ... and a bar between them ... driven in near edges ... not the bar ! Use mechanical forces to your advantage ....

 

[MattW]

Be careful driving screwdrivers through the filter - people have punched holes in the crankcase doing this.

well knowing my luck I decided against a Norman Bates style frenzied attack of the filter with a screw driver and for the pricely sum of $115 AUD(about 3 pence in your money) purchased a filter tool kit (you have to buy the kit see, dont sell them seperately) and with the sandpaper trick (thanks Steptoe) its out and I am the proud owner of a filter removal kit I dont plan to ever need again, thankyou K&N. In all the excitement and subsequent celebrations , I cant remember if the filter has an inner O ring on the thread or just the outer one on the rim.I might be getting confused with the fuel filter on the landrover, or I have lost it, anyone tell me which it is?Thanks.

just the outer one mate, non on the thread......thanks for the entertainment, we were with you every step

and from the other side of the world, that was strangely comforting!

and with the sandpaper trick (thanks Steptoe) .

It's the easiest and most sensible way. And never failed me whenever i've had to resort to it.

 

[Uncle Crumpet]

yep, after frigging around and getting the paper aligned "just so"amazing how much torque you can apply without slipping, especially as I was using a filter socket too big for the filter in question.

Except when some eejit splits the spotwelds between the screw on flange and the outer casing

When you refit "oil your gasket" and screw the filter on by hand till it's "gasket makes contact and then just tighten another three quarters of a turn"

They are the instructions in french on a Mahle 1200 oil filter the english would have you screwing away till you drop with no measurement given

dont worry, done to spec this time!
