Oil filter removal issue

the PO has chewed up the nut holding on my oil filter on my xj750e II
basic 750 lump i think what's the best way to get it off.
I was thinking make it perfectly round and tap a 17mm nut over and apply
some weld and then replace the centre shaft and nut any advice would be gratefully received.

 

You can buy rounded over bolt removers. Sockets with great grip to remove rounded over bolts. Those and an impact wrench or a long lever works wonders

 

They have sockets at home depot... dig right into it.

Also something called an alligator socket, it's a socket with like 40 pins in it that shape to the head, and then grab. Don't think I'd use one on a bolt that is potentially 'frozen' though.

My suggestion, kroil the bolt real good, then let it soak. Head out to a bigbox hardware store. Get a set of those 'nut grabbing' sockets. (lol... nut grabbing)

Anyway, they should work. If not, you may have to try a strong pair of vice grips on there REAL tight.

 

Heck, try the vice grips first, save the money on the 'nut grabbers'. lol

 

LOL :lol:

 

I had the same problem with my oil filter bolt. A PO had rounded the bolt head so badly that they welded a replacement nut onto the end of it. Unfortunately, they did such a sloppy job with the welder that I couldn't really even get a wrench or socket onto it.

I ended up taking an old socket that was about the right size and literally hammered it onto the bolt head. Once I got the socket on, I was able to use an Impact wrench to get the bolt loose. It took me about 2 hours total of arguing with it before it came loose...

 

Same problem here, but not quite as bad from the sound of it. I got one of the alligator sockets dpawl31 mentioned, worked like a charm.

 

Common problem unfortunately. Replacements are available for about $15

 

You know what's really sad? The torque spec for the bolt is CAST INTO the housing (metric, but it's there nonetheless) but apparently oft-ignored.

 

I don't think it's a torque thing as much as a time-since-last-removal and no-anti-seize problem.

Mostly the anti seize.

 

Air guns know no torque limit (it's a joke I know most have torque chucks)

Funny thing is I'll bet a ton of folks that go no farther than oil changes do not own a torque wrench. Just go gut tight.

 

I -have- a torque wrench...but so far the only thing I ever do is change the oil, and I always forget to bring it up from my workbench for that.
