Broke a screw while changing oil...

[ray_ray]

yep... that bolt could be sitting in there loose if it has not bottomed out on anything ... If so, you can carefully get it to screw back out by taping on it .... won't be easy but if you can see it move any when you touch it ... It might screw out on its own with a little help...

Find someone with heli arc, have them weld a blob onto the bolt then vice grips will come right out, done literally hundreds this way.
Easy outs will spread the threads tighter, and it's to hard to find the true center of the bolt. If drilling always use a LH bit sometimes they will catch then spin right out.

Everyone should have one of these sets when working on you're mortorcycle. These are by far the best extrators I've ever used, they come with pilot bushing to assure that you get the hole dead center, left handed drills so you might actually snag the broken screw and unthread it while you're drilling and the extractors are straight fluted rather than tapered so you don't end up flareing out the bolt and wedgeing it in tighter than when you started. The small kit is about $80.00 and will handle most the bolts we have on our bikes. Trust me, if you buy one of these kits you'll be dancing with joy next time you break a bolt.

With a job like this the key thing is patience, then technique and the right tools. Guys that get in a hurry, or that get rammy, usually are the ones left with a mess........ These jobs need to be treated a bit like brain surgery- Careful, slow and steady.........

Success! I got it out in about 5 minutes of work! Used one of these:

and it came out like a charm. Finding the center was a little difficult, but with enough patience and going slow enough I got it. Went to my Husky dealer, they didn't have the exact nut but they had one that would fit, but was just a bit too long. They were nice enough to give it to me for free (Thanks Tri-County Powersports!), and I went home, cut it down so it was shorter, and it works perfectly now.

Now I'm taking the rear wheel off for some new tyres.

Also, is there a secret to getting to the nut to adjust the shifter pedal? As is, I can't get my boot under it to shift for crap, and I end up missing a lot of shifts and looking like a total idiot.

Cool .. that tool is some sort of new fangled easy-out ...glad it worked ...

The shifter bolt is a little hard to get at but it is possible ... I had to hold my shifter up with one had to get a good solid box-end wrench on it ... U don't wanna strip the head off this bolt so be sure to have a good solid hold on it before trying to turn it ... Use a box-end wrench or socket for this ....

ba-bingo!

+ 1000. the drilling heats up any thread locker, makes it soft and the little devil comes right out on the bit, most of the time before you expect it. reverse drill bits are the shizle. get some.

rajo- correct, those are the BEST type of extactors.

when drilling ALWAYS make sure the screw and drill are plumb/level. this has the largest affect on things. if the hole is crooked, good luck.

nothing is more satisfying than getting a busted screw or bolt out. talk about a huge weight off your chest!


gotta love TCP- those guys are the COOLEST.

Sounds like maybe your problem is already solved? The best thing to do is put the screens back in, pack the screens with a shop towel that has tight fibers and will not come apart in your motor. Then get a smallish drill bit ( not micro because you don't want a broken drill bit in the middle of a broken off bolt in that particular spot), drill it out with a 1/8 drill bit, then a lil larger and use a bolt extractor. This kind I have never had luck with particularly the smaller sizes break easily.

The 4 flute kind with straight flutes, the tinsel strength is 4 times as strong. Remove the carcase threads and never do that again. Then you can vacuume out the metal shaving while removing the shop towel and screens.
Good luck!

Careful! Don't use too much torque!

I used a wobble adapter. Worked good!!

Same thing on the same bolt happend to me on the last oil change. I was only using a small 1/4 in rachet but still broke it. Used this:

The bolt actually spun out while still drilling the hole in it. Pretty good product. Funny part is when I went to install the cover with the one good bolt I had left while waiting on the new bolts to arrive, I broke off the second bolt too!!! What's frustrating is I broke the second bolt even though I was using a torque wrench set to the 5.8 ft/lbs as called for. Guess I had already over torqued it before and weakened it. End of the story is both bolts broke, both bolts are out and the new ones arrive today. Hopefully I don't break those too! Then I'd be SOL for my riding this weekend.
