Wow i just f%&ked up.

A family member had my torque wrench. I did the oil change any ways. When putting the filter cap back on I guess i over torqued and snapped one of the bolts.

So it looks like the bolts can be bought and just kind of reverse thread in there. I tried removing the bottom one and it comes out like butter.

The top right one though, the one that broke I am having difficulty with. Its in such a small space. And it doesnt seem to want to loosen.

I can get my smallest vice grip plyers on it and do a 1/4 roatation. But once released, the bolt just twists back the 1/4 rotation. I dont get it. And going at it horizontally isnt working at all, the plyers just shreds the bolt.

Any thoughts or mcygyver ideas on how to get this damn thing out?

I would love suggestions.

yeah, its just a stud, go down to canadian tyre (you dont live in canada ??? why not!!! :angeldevil: ) and pick up the removal tool.

this site shows two types, although I would just start with a small vice grip pair of pliers. If you have not damaged the threads too much yet,  look up double nuting the stud with two nuts,  lock them together and just wind out the stud with a wrench

I was also going to suggest putting two nuts on there if there is enough thread. The lower one is blocked by the second nut and you can just remove it with a wrench or socket/rachet.

If there isn't enough thread left to fit two nuts, the other options are:
-Using a dremel cutting wheel to add a slot to the tip and using a flat head screwdriver
-Using a screw extractor tool that grips the outside of the stud
-Using a left hand drill bit
-Using a left hand drill bit to drill a hole and then installing an extractor inside the hole
-Drilling out the screw completely and installing a helicoil style threaded insert. The nice thing about this is it is actually an improvement long term because now you will have stainless steel threads instead of aluminum threads.

You may have to remove the exhaust and front forks to have enough room to get a dremel and/or drill bit in there.

For future reference, the specified torque value on those nuts it super low. All it has to do is slightly squish the soft gasket. I usually don't bother with my little inch pounds torque wrench and just grip the spanner right at the rachet and give it a little nip snug. If you use the full leverage of a wrench you will end up in this situation again.

Thank you very much gentlemen!

the two bolt thing worked perfectly!

I now know to be more careful with them!
