Changed my oil today, stripped the threads on the posts that the acorn nuts screw onto to hold the oil filter cover on. :mad:

Turned my bike on, "POP", bottom knut comes flying off, oil everywhere.

Can I replace these posts somehow or am I pretty much screwed?
 
You should be able to remove them with a stud remover. the hardware store probably has replacement studs
 
Yep they can be removed. If you don't find them at the hardware store, bikebandit has em for .98 cents.
 
Alright thanks for the info. I'll try getting them out with some vice grips tomorrow. It's dark here and I'm not moving the bike into the garage with it dripping oil everywhere.

Just when I got the brakes buttoned up and was ready to ride tonight...

:(
 
Anyone have any ideas before I run out and buy a stud puller? Vice grips and pliers didn't work, and I'm hesitant to buy a stud puller because it might not fit down there because its pretty tight around the oil filter cover.
 
I just called every hardware store near me, no one has a stud remover. :(

What now? SIGH

If there is enough thread left, you can find some normal nuts that will thread on to the stud (ie. not acorn nuts) spin 2 or 3 of them onto the stud, tighten them together, then get a long socket over all of them, and try to pull the stud. Can't guarantee that will work, but thats how we used to get cylinder studs out of vespa cases. May be worth a shot...
 
if there are any threads left, jam 2 nuts (6x1.0) together and turn the inner one to remove the stud. or put one nut on and weld the sucker.
 
If you use the small vice grips, you should be able to grip the stud and unscrew it very slowly and carefully. Work it back and forth, apply penetrating oil very liberally, they'll come out. Make sure when you replace them that you get the right metric thread for the stud (I can't remember which it is at the moment). Normally I'd say double nut it, and back them out that way, but if you've stripped all the threads off of the studs, obviously, that won't work. (on edit): I also have a very small pipe wrench (6") that I use for removing stuck studs.
Good luck, work on it carefully, it takes time to correct a problem of this nature.

There are some threads left, just not near the end where the little tip sticks out to hold the filter cover on.

I hadn't thought of the two nut idea, thanks guys. You guys are why I still have my bike and it hasn't been set on fire yet. :D
 
when this happened to me....

when this happened to me....

I just borrowed a dremel tool from my neighbor, cut a slot in the top and used a flathead screwdriver to get them out.....could maybe use a hacksaw blade manually I think.....
 
I had the same thing happen. Vice grips and several beers worked.

I replaced the studs with bolts (M6s if memory serves me..) and it seems to work well.

Ok, all the studs are out, the nut idea worked great.

Zach, do you know what size thread bolts you used? I think I'm going to go the bolt route too but I need to know what size the threads should be.

I'm calling it thread size but I don't think thats the right term, how thick the shaft the threads are on is what I'm wondering.
 
M6 = 6mm, not sure the pitch though. Take one of the studs with you to the hardware store and match it up. Should only cost a couple bucks.
 
I think they're garden-variety M6's, but as jmanz recommends, take one with you to the hardware store to compare. Some lock washers would be a good idea too.
 
SUCCESS!

Thank you everyone who posted in this thread and helped me.

I went to Ace hardware, found three bolts that matched up with the studs, and got a split ring lock washer for each one and everything is working great, just got home from a nice evening ride and not one drip of oil anywhere!

:dancing:
 
Draketh, I don't have any experience with this, but I recall posts in the past where bolts were not the recommended route. The reason was that the aluminum engine block is obviously softer than steel. If you are continually screwing bolts in and out, then the threads in the block will strip in short order. The bolts will work fine now, but the next time you need an oil change you may want to replace them with the appropriate sized studs (you can locktite them in, and the chances of stripping on a steel stud are far less likely).

I hope this makes sense, let me know if need further clarification. FWIW I will need to do this to one of my studs next time I swap out the filter.
 
Now that you have a temporary solution to your immediate problem of a severe oil leak ...

please consider a more-permanent solution. Every time you change the oil, you will be adding a little more wear on the threaded holes in the case when you remove, then re-install the bolts. Fixing those worn-out holes will not be fun. Get the parts to do the job right. Get new studs and nuts to put back in there. It is better to have the wear happen on a replaceable part than it is to have it happen in the aluminum case. :-k

edit: Looks like J_C had the same idea, but typed a bit quicker. :o
