oops...I snapped a bolt

[kjoslin]

While putting the front left rotor on, I over torqued a bolt and snapped it.

How can I remove it????????

Is that a common bolt that a hardware store would have; or a special bolt that must be ordered from a Yamaha shop???????

Anyone have an extra that they would sell me???????

thanks,

Keith

Hey Keith,

IT's a metric bolt, you should be able to find one at your local hardware store. Not sure of the GRADE, probably 5 vs. standard?

If you remove the Rotor, you may have enough of the old one sticking out from the rim to be able to grab with a pair of lock/vice pliers and rotate out. OR you can use a dremmel/diamond burr to cut a slot in the end for a large screwdriver/impact driver?? Or, file it so that it's flat, centerpunch it, and then attack it with a reverse drill bit small enough to drill into the center without threatening the outer threads of the aluminum rim, it'll probably turn out as you're SLOWLY drilling it!

instead of a reverse drill take the wheel off and turn the fork leg
then drill it from the backside
when the drill binds up it will turn the bolt thru the hole
and out the front side

oops skip that last reply i thought it was a caliper bolt

Grab'it set.

You can get a set of Grab'it bits from most auto parts stores, we use them on safes and they work great. they have a cone shaped bit on one end for preping the bolt and a cone shaped extracter on the other for removing the broken bolt, you just chuck it into a reversible cordless drill and no more problem.

Hi Keith,
Grab'it bits? You learn something new every day if you ain't careful. I will look them up.
Once you get the bolt stub out replace all the brake disk bolts with Allen-head cap screws. Allen wrenches dig into your hands so that the pain makes a cheap torque wrench.

thanks for the great tips...off to the auto parts store.

should I use LOCKTITE in the bolts OR ANTI SEAZE on the disc bolts?

thanks,
Keith

rotor

Those rotor bolts should have a lock tab plate, just bend over the side of the bolt head. If not, use a few drops of locktite blue.

[kjoslin]

I was able to get on enough of it (with disc off) to back it out.
I also found a replacement bolt at Lowes. Thanks all!!

Is it BAD to use anti seaze on these bolts????
I do have the lock tabs in place for most of the bolts.

I use anti seize on all steel to alloy situations. If you torque the bolt properly there is no issue to use it.
