Oil Filter bolt
« on: June 15, 2010, 06:09:34 PM »
Ok, another common problem, the oil filter bolt is pretty much impossible to remove on my bike.. Just pondering, Is it a Rh thread or left?? Just wanted to make sure, cause it isn't movin when I 'm turnin it left.. I guess its off to the store for bolt extractor socket...
I've read the other threads relating to this but could not find answer..
Thanks

Standard threads.  Smack the head with a hammer to shock the threads, and try again.

Good luck, man.  I'm not sure what kind of bike you have, but on my cb650, (both of them, actually...) the steel bolt had organically welded (electrolytically welded?) itself to the aluminum housing and the only way to remove it was to carefully grind off the top of the bolt. I'm not kidding.  We'd ground the bolt (and the washer-like disk under the bolt head) down so thin it was like tinfoil and it was STILL not coming off.  Once the head of the bolt was off, though, and the housing could be removed, the remains of the bolt spun right out with finger pressure.  It was the darnedest thing.

I sincerely hope that's not the case for you, but if it is, be very careful about how you grind it off- if you damage the housing, it may leak with the new bolt.  Some have luck with heat... I didn't.

I found this on a 750 engine I bought.
Creative to say the least. ::)

Yeah its like Kit said. You need to carefully take the head off the bolt with a grinder, Dremel, etc. Once its off the housing will come off and you'll have something to grab. Though you likely won't need to. The head of the bolt is corroded to the housing. Its not stuck in the engine (likely).

You may need to true up the surface of the cover from your grinding activity, again as Kit said, to avoid a leak.

Hi all, I use this tip when installing the filter bolt. get some copper anti seize and put a little dab on the threads and under the head. it will never bind again. Also do not over tighten this bolt. Latter

GOOD TIPS!
I had to replace my oil filter housing because I over torqued the oil filter bolt with my little girly arms and cracked the housing. :-\  It happens.

ah ok, hen I defer to 750 owners, though I think the setup's similar.

Heat it with a torch as well as hitting it with a hammer. Aluminum expands more than steel, and if you heat it up to third degree burn temps it will come loose rather easily.


Hope it helps...

If you're not already, use a six sided socket.

X2, stay away from 12 sided stuff. Go with the 6.

Pipe wrench is what i had to do to mine.  Then I bought a bolt that had a 17mm head on it.  You can find it on Davis Silver Spares or Ebay form time to time.

I am a user of the 17mm bolts myself. But I think it is important to emphasize...

Bolts with squishable washers /Orings should be tightened as follows: hand tighten as much as possible (us a glove), wrench tighten to the squish point, then go 1/8 to 1/2 more to squish it. Ride it, and tighten it a bit more if it leaks.

This goes for... valve tappet inspection covers, spark plugs, oil drain plugs, oil filter bolts, exhaust bolts... maybe some others.

That's what I do, suit yourself.
PS: Use fresh squishables whenever possible.

I was told to put a magnet to it, if it sticks weld a nut to the end of it and crank away.  I might try some of your ideas first.  anyone know if the bolt is steel or alum?

steel
Yup steel, makes one wonder why the nut rounds off so easily. Simply put, they are routinely tightened too much.

A dab of anti-seize under the lip of the flange makes sense.

  I had the same problem, I drilled out the end and used an easy out. that didn't work.   In the end I welded a wrench to the bolt and used a hammer to break it free.
