Oil Filter Bolt Extraction

[SCook]

Suggestions Needed for XJ 1100.

Problem: Head on the bolt which goes through oil filter cap and oil filter is rounded off. Bought a new one and I've tried every extraction tool / socket / vise grip etc that I can get and to no avail. The thing won't budge. I even tried a chisel but it was just cutting through the soft metal.

The bike has 23K miles on it and I have no idea how long the filter has been in it and while I've changed the oil it's driving me bonkers that I can't change the filter.

Any suggestions would be welcome.

Help!

is a thread about the same problem that you are having. Good luck getting the thing out!

Disconnect the battery and brain box, than have a 19mm nut welded onto what's left of the bolt head. That ough to give you enough purchase to get it off. BTW - this is a good idea for anybody who still has the original 12mm bolt head.

You'll never get the bolt out. Just give the bike to me and start over with another bike .
Just be more stubborn than the bolt. It's a karma thing .

Another approach I just thought about, since you already have a replacement bolt, is just cut the head off of the one you have using a dremmel cut off disc. Just need to be a little careful against the oil filter housing not to nick it too much. However, the bolt seals with an extra O-ring on the bottom, not just a smooth contact with the bottom of the filter chamber!

Once you get the head off, you can slide the chamber down off of the bolt, then you'll have the entire bolt to grab ahold of with pipe wrench, lock jaws, etc!!

use an air chisel to move the bolt. just a couple of taps at a time and youll work it free. I had the same problem back in '92.

Thanks

Looks like I'll be grinding that ol bolt head off but before I do I'll try that small pipe wrench idea.

Thanks for the suggestions.

One last thing to try....
If you can get the clearance under the bike, use a hack saw to saw the top of the bolt, as in a screw driver slot. Then try an impact hammer on the bolt. That may be all you need to break it.

As we all know, these bolt heads are very soft. I was able to get my rounded bolt out by hammering a smaller socket onto the bolt and removing as usual.
