broke a bolt

[hairman]

Bolt in my seat broke off even with my seat. Is there a simple way to get this out? Thanks

Your tagline doesn't say which venture you've got, but on mine access would be easy, so with the tip of a screwdriver or a centre punch and a hammer you would be able to tap it out. Alternatively a drill through the middle would probably make it wind out (heading into the mudguard gap) - you'd then have to pull it off the end of the drill bit before withdrawing it - or release the bit and push that through too.

 

Is yours less easily accessible than this ?

 

Was the seat bolt overtightened or very badly corroded ?

I have a 1999 Yamaha RSV. I was thinking about knocking it out with a chisel and JB welding one back in place because it looks like it is molded in the seat. thanks

If the head twisted off, sounds like a job for and " Easy Out " Tool .

The head of the bolt is molded into the rubber part of the seat. The bolt broke off flush with the head. I am going to have to get underneath the head of the bolt to try to pry it out. The first picture is the good bolt that is still there. The second picture is of the bolt that broke off.

Looks like a prefect candidate, for an " Easy Out "

The stud is molded in. I would drill it out or cut the seat pan and drive it out, then glue a new bolt in. Rod

Tim,

 

One solution is to grind the surface of the stud off flush and then drill and tap it for a 6mm X 1.0 pitch bolt. Then get a 20mm M6 bolt, cut the head off and clean the cut threads up. Now use some heavy red locktite and thread the end you cut into the stud and let it set up. The best solution is to take the seat cover off to where you can screw that same 20mm M6 bolt down from the top side with the same locktite.

 

Hope this helps,

I agree with Rick

You might try a left hand twist drill bit with the point ground so that it digs in and "grabs". Even if that doesn't pull it out, you have a hole for an eazy out.

 

OR what's that magic "As Seen On TV" thingy:think: that is guaranteed to remove any stripped or broken bolt?

Well guys,

 

The main issue is that this is not a bolt. It's a large slug about the size of a dime and maybe 6mm thick, molded into the seat pan with a 6mm X 1.0 pitch stud machined on one end. And what has happened here is that the stud broke off. There is no way I would tear this molded slug out of the seat and JB weld something into the seat pan. Just drill and tap it for another stud? But, maybe JB weld the stud into the threaded hole rather than using locktite?

 

Hope this helps,
