Broken bolt

So I was going to rebuild my starter because it keeps slipping, long story short I didn’t read directions and ended up breaking this bolt. I didn’t put much pressure on it at all and it snapped. Can someone please steer me in the right direction to get the remaining bolt out?
It’s about at 6in bolt and the bottom portion is what broke.

The opening is where the starter was at to give a reference where the bolt is.

 

It’s a 1985 xj700 btw.

 

It ain't gonna be easy.........Can you get a hand drill over the hole? If you can, get a drill bushing that has an OD equal to the OD of the bolt that snapped, ID of the bushing I'm gonna guess that a 1/4 inch would work. The bushing will guide the drill bit so you drill the center of the broken bolt so you can use a bolt extractor. I would even be tempted to use a left handed drill bit, it could catch and screw the broken piece right out.

Above all, slow and steady are the key words here.

Good luck!

 

how much of the bolt is in there a pic of broken bolt would show us. looks like it snaped at the threaded portion..
I think that is going to require splitting the cases

I would start by soaking it with pb blaster or kroil (penetrating oil) daily befor starting any attempt to drill it out with a left handed drill bit

maybe plug the hole and ride it as is

 

I should be able to get a drill over it. Thankfully I already had the carbs off too so that’ll help!
Thank you!

 

I’m not

I’m not sure exactly how much is left in there. I’m guessing 1/4-1/2in maybe.

 

Here’s a pic of the bolt.

 

this an airhead or watercooled 700?

buy the replacment bolt first to see what your working with/against
did any of the thread come out?..


looks like a 6mm diameter, you did get some of the threads out

maybe you can still thread in a bolt and shorten the threaded length i know it is a hack move but if you try to drill down and the case threads are exposed you may mess them up
so you realy need to know if a new bolt can thread down the hole first so you know what damage you may do

 

Air cooled. Some of the thread did come out but it barely turned when it snapped so I don’t think much of the threads that were actually screwed in came out.

 

From everything I’m finding replacement wise it’s showing the bolt is a 6in bolt. Meaning there is still about 3/4in left in there.

 

You said I could plug it and drive it as is? When I pulled the bolt out it had oil on it, is there any real significance to that bolt?

 

problem your going to have is finding a left handed drill bit that long to do the job. I doubt you will be able to fit of find an easy out that long.
if you are sucesful in finding the tools you may mess up the top threads.

1 this is a case splitter for best results.
2 next would be seeing if replacment bolt will thread in and how far/many threads it catches.
may be possible to shorten bolt and install.

3 replacment motor may be the cheapest way out of this.

4 plug hole and ride it as is

 

yes it is holding the cases together likely securing a bearing in the transmission.
or secures the starter clutch
see if you can find a sp;it up 700 motor on ebay and you will be able to see what eactly the bolt is securing.
i am looking now

cases run from 80$ shipped and up not my recomendation just saying

 

I don’t think that’s something I want to get into. I also don’t want to try to drill it and possibly ruin it even more. I’m going to try and get a replacement bolt and see if I can get it to catch even if it’s just the slightest. If that doesn’t work I’ll seal it and ride! (Hopefully).

 

you could measure the hole and tap the top for a plug.

I do not suggest new cases if you were to price it out a replacment motor would be cheaper.
this would give you time to fixx the motor you have.
even a 750 motor would fit.

problem with the 700 motor is piston rings are not available.
it may be possible to swap top ends from the 700 to the 750 and make it a 700(more hp) not sure as it seems to be uncharted ground.

 

What you need to do is pull the engine and take it to a machine shop. That bolt does more than just hold the starter on.

 

Thanks I’ll probably end up doing that.
