oil filter housing bolt

Postby aznyaz » Sat Sep 29, 2012 12:58 pm



I have a seized oil filter housing bolt. My 12mm sockets and box end wrenches have already rounded the hex head. I'm thinking of filing down the hex so I can get and 11mm on but there are no guarantees that will not do the same thing. Has anyone had this happen before? I even tried using a vice grips on the edge of the flange and a hammer and punch on the bolt flange as well, just tapping it to see if I could start it moving around, to no avail. I need help!

Consider the obvious first, lefty loosey , etc.

Make yourself comfortable and put the bike up to where you can work on it. Heating bolt not a good idea.

Consider the bolt a sacrifice to the spirit world and a replacement arrives before starting. The goal is to save the case and not burn the place down

Drain oil.

Punch small centre dimple. Depending on how chewed up it may be the centre may not be apparent.

Consider this. I worked in a steel stud rolling mill about 35 years ago. We got a new mill and we worked on each rolling stancion to adjust it. Each stancion had an upper an lower shaft to hold dies that would shape the steel. These shafts were about 1 1/2" in diameter and had nuts nuts on the ends. There was one nut that absolutely refused to loosen up. After hours of scratching heads I took a close lood at the end of the shaft and could see the last bit of thread poking out through the nut and determined it was a left handed thread (lefty tighty in this case). I have never seen this happen again in my life except for some obvious applications where a left hand thread made sense, and this experience has always stuck with me, so unless this oil filter housing bolt has left handed threads, I am turning it in the correct direction.

As for the easy out, I am probably going that route since the exposed portion of the bolt is a chewed up mess now.

Thanks for the input.

If you cut it off flush with the filter case, you can remove the case and have all sorts of room to grab whats left.

Drilling it out seems drastic , but if you decide to do this I suggest you use a left hand drill as it may help the bolt to come out witout the use of an easy out. If not the you can still use the easyout

I may be stating the obvious, but use PB Blaster. That stuff has loosened everything I have ever tried it on. Maybe I should try a little on my wife? :twisted:

No harm in spraying naptha and petroleum on the bolt (PBlbaster). Pretty much the cap and the engaged threads are the only part not bathed in oil. One might suspect the threads are the issue.

The alternative to cutting the head is to enlarge the drill to ream out the bolt and finish the inevitably slightly off centre hole by hand to avoid damaging the case. The case is soft.

How about filing down flat the oposite sides of the bolt-clamp on a vice grip-and then whack it sharply with a hammer.Sometimes a quick hard whack will break a stubboron bolt loose. Let us know how you get it out.Regards, Johnyy

There's an compressed o-ring in the way. The engaged threads are on the "oil side" of things.

Thanks for all the input. I used PB Blaster overnight, used heat (some say do and some say don't), found a youtube video with a guy with the same year bike and the same problem. The only thing he had that I don't are an air compressor and hand grinder, so he could flatten two sides of the bolt head and he finally got it out with vice grips. Could it be the aluminum threads have gauled where the bolt screws into the case? I can't figure why nothing has broken loose with everything I've done so far. So, I've put the oil in and will run it with the old filter and when I get the new bolt (been ordered) I'll either take it to the shop or get my own easy out.

I didn't quite follow on the left hand drill part. Is there such a thing? I guess so. I've seen left handed threads before. Is it remotely possible that this bolt has lefty threads?

Try heating it and the surrounding metal up with a torch, then touch the bolt with an ice cube for a few seconds before turning it. The surrounding metal will stay hot (and expanded) while the bolt contracts from the coolness of the ice cube, sometimes freeing it up. I've used this technique successfully more than once on stubborn bolts.

I might give it a try later although there's not much left of the bolt to grab onto.

There are left handed drill bits.

http://www.mytoolstore.com/hanson/hanson.html

If you have one the drilling may be helpful in extraction.

I had also wondered if one could cool the bolt on an otherwise hot motor sufficiently to ease extraction. Might stress fracture the case?

I presume it would involve draining oil and covering the bolt head and filter case with dry ice (CO2) or using a cartridge fire extinguisher. (note to self, must find an emergency requiring a chilled can of beer.)

The problem I see with trying to use temperature to try and break the bond is the insulating effect of the filter case air space, filter and oil. There's an inch and a half or so air gap to try and overcome, and/or the length of the bolt.

My money is still on bolt head removal, to gain direct access to the actual bolt and threads, after filter case removal.

Try wing admins suggestion of heating the bolt somewhat - NOT CHERRY RED though. The bolt is of good quality STEEL and it screws into ALUMUNIUM. You call in ALUMINUM I think is the USA. The aluminium has a higher coeffient of expansion than steel and it should open up a bit allowing the steel bolt to come out . Have you tried a decent pipe wrench on the chewed up bolt head? Its a normal right hand thread NOT a left hand thread. Try giving the bolt head a sharp smack with a hammer to help jar the threads.
I would cover upo the front wheel mudgaurd with a decent sized rag in case you scratch it trying to get the bolt out :)

No arguments there is more than one way to do this.

Note - It is a flanged bolt

Oops, sorry. It was late and I had to give my daughter a ride home from work VERY late, and I was soo tired that I actually was envisioning the air filter bolt. Sorry about that. :oops:

I would first try a good pipe wrench, then an impact driver. I have a 19.2 volt Craftsman one that is variable speed torque. It has come in handy. Have you ever had it off before?

Thanks again for all the input. I haven't tried the heat and chill method yet but I have screwed the bolt up so badly that there's hardly anything to grab onto. I may need to get hold of a decent electric hand grinder to reshape the bolt head. I have tried pipe wrenches and punches to try and tap it around but nothings working. When I get the new bolt I may try an easy out. Any recommendations whether to use the reverse thread type or the square one? I'm tempted to take it to a shop just so I don't screw it up anymore.

Use the reverse thread first. Remove all the cuttings with the bolt and clean the filter case.

Master of the obvious here again - Sparks Oily rags and gas don't mix.

i cut a slot in mine with dremel tool,then used an impact driver(hit with hammer type).came right out.if i remember right the replacement bolt i ordered came with a larger bolt head on it.

I might try that before taking it to the shop. I need a new dremel tool and an impact driver.

If this ever happened to me and I happened to strip the bolt somehow or rounded it, I would take a dremel and cut two horizontal cuts into the bolt and make it so I could place a large adjustable wrench on it, so reshape the bolt for the wrench is what I'm saying...I hope I never have to do that.. :shock:

Right now I'm without several tools such as a decent dremel and and impact driver (which would be a big help), so I took it to the shop yesterday to have them do it. No riding this weekend due to rain. So, I should be all set some time next week.


Thanks again for the input.

It kind of follows the "...for lack of the proper tool" scenario. After exhausting all of my tool options I took it to the shop and the mechanic used large, curved jaw vice grips
on the flange of the bolt, since the bolt head was pretty much trashed. It took him a couple of tries before the teeth bite into the flange, but once it took hold it came off prretty easy.

So, the moral of the story is make sure you've got the right tool, no matter what comes up.
