Sheared manifold stud? Try this!

[AndyE]

All,

Doing a bit of work today on my VTR, I was removing the exhaust system.

Unfortunately one of the front manifold studs sheared, only leaving about 8mm protruding. I had been soaking it in Plus Gas for a few nights in preparation, but obviously that's not good enough!

I've been in this situation plenty of times before with different studs/bolts - and never succeeded with an Easy Out. They would just snap off in the hole, making a bad problem worse.

Mole Grips *never* work for me because you just can't squeeze the stud hard enough.

I have had success with welding a nut to the stud once.

A couple of times I've drilled and tapped the hole which takes ages and is hard to do accurately on an important/expensive component.

However, this time I thought I'd have a go with a different method - a vice!

I whipped the head off and clamped the vice around the fat unthreaded part of the stud - and tightened the handle using a big bar. It was so tight the vice was creaking.

Then I turned the head by hand. With a huge crack (where I thought I might have damaged the head or snapped the vice) it was undone.

This is definitely worth a try if you're stuck in this situation :-)

Normally your vice would be mounted on a surface, but I haven't bothered since moving house about a year ago!













Good luck!

Unorthodox, but obviously effective

Good un Andy

Are you going to copperslip or threadlock the replacement?

I had the same problem with mine and it was the bottom stud like yours gave it a good soaking with wd 40 overnight
mole grips still no good
few sharp blows on the end of the stud with a hammer
and the mole grips spun it straight out
might be worth a try for any one else in this situation before removing head

I did try giving it a few knocks before trying to spin it out with the two nuts - but couldn't budge it at all.

I had most of the bike apart anyway (bought it last week as a non-runner, it's had a front CCT failure. I had planned to take the front head off to check for bent valves - No damage thankfully!)

Given that this stud has probably been in there for over ten years, I was chuffed to be able to get it out at all!

Redstorm, your avatar thing is scary! Horror clowns frighten the sh1t out of me....

I usually give it a bit of heat with the gas, smack or 2 with a 2lb hammer then the mole grips will work.

Seconded, I suffer from coulrophobia too

Whatever the feck that is....

Well you'll be able to sleep at night knowing the clown avatar has gone (for now), but if he's not here, where is he? could be in your attic, behind your wardrobe, under your bed Muaahahahaha Muaahahahaha


Damn me if I can post my previous (original) Rossi animated avatar to celebrate damit!!! Tried half a dozen times with no luck - phooey!

Oh well have to stick to current one till I figure something out.

Rossi, really messes with your mind!!!!! Muaahahahaha
