Axle clamp stud removal
« on: July 06, 2021, 06:40:01 PM »
Evening all,
Spent the last two days stripping and rebuilding the front end on the GSX1100EZ as there was a weep on one of the fork seals.
Heavy bugger to work on but all went surprisingly smoothly until...
Tightening up the axle clamp nuts and one of the threads stripped at the very end where the nut fits.
I'd like to pull out the old stud and fit a new one but never tried this before and wasn't sure how easy stud removal might be.
Seen a few stud removal tools on Amazon so hoping someone may have a recommendation on which type to use.
The full stud is there with just the last bit stripped so have good thread above that - could try screwing on two nuts as a first option.

Any advice very come - really don't want to strip the front end and forks down again so hopefully can do this in situ.

Cheers,
Andy

Hi Andy. Before you buy anything, try locking a couple of nuts against each other on the good part of the thread and see if you can just wind it out.

Go with the 2 nuts,

Maybe apply some heat, and penetrating fluid, leave it to soak,

You could try tapping the stud with a hammer, it may help to break the seal.

Thanks guys,
I'll try the two nuts approach first and hopefully it'll work.
I have no idea how well these studs are normally fixed into the fork leg and whether they are 'easy' to remove - guess I'm about to find out tomorrow when I go back to it.

Cheers,
Andy

Good pair vice grips on the smooth part of stud and as tight as you can snap them together, especially if your threads are bad.

If you can, get the penetrating fluid on as soon as possible,

The more you can do,the more likely it will work,

For best results with 2 nuts use serrated shouldered nuts. Thread a ring spanner on first, tighten the serrations against each other and they'll grip like a scouser holding onto his rent money.

Oddjobs mention of two serrated nuts is a new one on me,  like it ! you live and learn !

Danger is , so much grip , watch you don't shear the stud at the alloy face, then you're in the s**t.

No heard that one either, nice to pick up a new tip, never too old or too stupid to learn! Never heard that one about the scouser either! 😂😂  What a sheltered life I live up in the North!

I have recently bought a Metric Set of these - I used some Imperial ones decades ago that were a RR apprentice tool. They work well but if the studs are really tight you do need to replace them as the tool distorts the stud slightly. Also always use a T Bar to avoid off centre sideways force.

They are ideal for re-fitting studs as well - they are a type of chuck arrangement - the three rollers that are offset inside the tool grip the stud - you can often fit the tool so it grips on the unthreaded section.

Update my 6 mm tool seems to big so I am in touch with the sellers as it does not clamp onto the stud as it should!!

Update of update - seller is ending me a replacement 6 mm unit.

Snap on do a tool with a threaded hole and taper outside that is clamped into the outer case and tightens increadibly tight on the thread with a 22mm hex on the top.
I have one in 8mm for when i was doing rd350lc exhausts mods, if i can lay hands on it you can borrow it for a deposit

Thanks again,
Tried to get the nuts onto the thread but didn't want to go on smoothly due to the mangled end thread.
I've ordered a stud extractor due to arrive tomorrow so hopefully will be a miracle cure!

Cheers,
Andy

When I'm soaking studs with penetrating oil I use a loose "O" ring over the stud to act as a small reservoir that I can fill up. 

Not very practical if you are working upside down though.

Get it hot when you try and undo it, some have threadlock on them and heat loosens it

Good reminder about heat loosening threadlock. Another use of heat I've used is to weld a nut on the damaged thread. The heat does some good and a spanner then fits the nut, I also "rattle" the nut with a light hammer  as I put some torque on the spanner, that's worked a few times, working the spanner one way then the other whilst hitting it lightly end on to tease the stud loose.
Anything's better than shearing it off !
