Stripped...

[the_Journeyman]

Stripped these.  I'm assuming just drill them?  The rearset is broken and the bolts seemed slightly bent from miles and miles of riding it like that or from the drop several years ago that snapped the rearset.



Anything to do but drill?  I obviously don't want to damage the engine case ~

Drilling should be your last attempt.  Try hammering a torx into them.  The torx should cut into the head and the hammering will help freeing the fastener

[the_Journeyman]

I'll give the Torx a shot.  Thanks!

Better still use a hammer operated impact driver with the torx.

2 broken 1/4" sockets (got a 1/4" allen tip to fit one of them) and one snapped (spiral/torque break)6mm Allen socket later I've got nothing.  I don't have an impact driver.  These are STUCK to the point I'm breaking name-brand stuff.  It's Kobalt stuff from Lowe's.



Blue circle - 1/4" allen tip.  Plenty to get a grip or socket on, but I've snapped two sockets

Red circle - Remnants of my 6mm allen socket.  Just a small amount, maybe 2-3mm sticking out.

Did you use a "TORX" bit like everyone said or an Allen. The torx has worked for me in the past with stripped allen heads.

[the_Journeyman]

I don't have a torx large enough.  Not to mention the weak point is what I've been putting on the end of the bits to turn them with.  The allen heads that are currently in the bolts are holding fine, so fine, I'm breaking my tools trying to turn the bolts.

You need to pick up an impact driver.

Either that or a heat gun...or both.

You should be able to find one for short money and it will be an invaluable addition to your tool box.

[the_Journeyman]

I've got a good heat gun.  I'll put the impact driver on my wish list.

Since you mentioned a heat gun, would heat help here?  I'm fairly certain the bolt shanks are slightly bent.  The one I broke my 6mm allen socket on hasn't moved at all and now I'm not sure how I'll get the socket piece out.

Can't hurt, but I really thin that corrosion is the issue.

The impact driver will help break that free.

If you get the bit out which you should be able to do with a punch and some judicious tapping in the right spot...

don't be shy...heat up the area on the case so you don't melt the rubber and hit the things with a hammer and spray some pb blaster or other penetrant.

Then use the impact driver that you've been wishing for.

....don't forget to order a 1/2 -3/8 impact reducer

[the_Journeyman]

I've already got penetrating oil on them.  I'll fuss with getting the broken piece out.  I've never had a bolt stick like this.  I'm thinking corrosion is part of the problem since I ride in all weather.  I'll then give some heat a shot, hopefully I can get someone on that bit that won't break.

I had the same problem in the same place, and kept breaking hex bits.  A Snap On  'L' hex with some additional leverage twisted about 90 degrees before the bolt started. 

[the_Journeyman]

Got the broken piece out.  Heated the case and put as much pressure as I dared so I wouldn't snap my other 6mm socket.  Still nothing.  More penetrating oil and it'll set until tomorrow.  Here's a pic of what I did to my 6mm.

Put a flat ended punch down in the bottom of that hex, and give it a few good whacks with a hammer.

[ducpainter]

You're gonna be real stubborn about the impact driver...huh?

What's the cost of the 6mm hex bits?
