Head gasket probs on legend

Hi,i really hope someone can help me here,my 99 legend has done its head gasket,when the repair shop started stripping down the head it broke a long bolt at the front,so its left the shank and thread inside the barrel/case assy,also one of the little bolts at front has snapped off,now i cant see how the longer bolt can be removed,would it be alright to helicoil the remaining part of the hole in barrel and use a shorter bolt,as it looks like ive got enough depth there,is this a common fault ,and should i use new head bolts,helpppppppppppppp ,cheers

 

I've heard this done somewhere... Get a metal drill bit sharpen the opposite side of blade with a file then use a reversible drill, drill into shank anti-clock and after a while should start unscrewing, if not too strongly seized, hopefully!!

 

Or alternatively use left hand turn drill bits.

Well done biglad, I thought they were as hard to get hold of as left hand screwdrivers

 

Repair shop should be able to sort that, either using above and/or stud extractor, they may need to warm it up, different expansion rates between alloy cases and steel bolt. Personally I would use new head bolts, you need one anyway, but personal choice , hope all goes well

 

many thanks for advice

 

when I was in engineering they used a spark eroder to remove hardened snapped off bolts taps etc, it removed them cleanly and left the thread untouched, so if push comes to shove ! but you would have to price that against the price of a new part, but sometimes these things can be removed with an bit of heat and an easy out,
good luck with it anyway.

i am going to make a start next week on it,its not my bike ,im doing it for a friend whos short of cash,cheers for the help/advice everyone

 

did you have any luck?

 

Hi ,no not started it yet as just had to have my little finger cut off on right hand,so will start in about 4 weeks time now,just hope we can save it ,cheers for interest

 

Good grief!! Can things get worse?? Sorry to hear that hope it heals quickly

 

If it is going to be weeks before you start, fill the stud hole plus gas or other penatrating oil, and keep it topped up until you ready to drill it out.....more likely to come out.
A bit of copaslip on the new bolts when fitted may prevent it from happening again
