The bolt is well and truly seized in there and rounded off first turn of the T25. Tried with WD40, larger torx, flat head in the gap, then cut a notch in the head for a bigger flathead. Finally started to drill out to then run an extractor bit but reached the limit of my ability/courage.
Anyone able to help? Beer and biscuits available
It's a hope rotor and pro2evo hub so wouldn't mind having both usable at the end of it
tried an easy out yet?
I have an easy out set, but not a suitable drillbit to do the pilot hole into the bolt
Drill the head off the bolt. Rotor is then off and bolt is no longer under tension.
As per Nixie - or try F&R engineering’s in Crosland Moor - if you pop along they would prob do it for the price of a pint.
As per Nixie. Do not use an easy out, especially on something that small. If everything isn't in perfect alignment I'll snap and you'll be in a far worse situation.
Actually that is very true - I don’t think I have ever successfully extracted a bolt with an easy out - they always snap, and then you’re in a world of pain!
Carefully cut/grind/file flats on the bolt head then molegrips to grip and turn.
Molegrips are one of my workshop favorites
Another plus for drilling the head off. Then lift the rotor off and if you really must, get mole grips on the headless screw.
Completely agree easy-outs/stud extractors at small sizes are a liability unless in the hands of someone with practiced experience and an understanding of alignment and application of force. Snapped toolsteel to head height in the mangled screw is not going to improve anyone’s day.
I’m in Hudds, will gladly sort it for but I’m on hols this week until Saturday. PM me if you want.
Thanks all, I feel a bit better about plowing on forward with the easy-out.
I've lined up a bike mechanic i know to have a go at it. She's done them before so hopefully she'll be successful. If not I may be tapping you up when you're back charlie
It depends why its stuck/rounded out.
If its clamping pressure then drilling off the head will relieve the pressure and you can just wind it out.
If it is corroded in that wont work.
Aluminium expands more than steel, heating with a heat gun/hair dryer/boiling water can often make a difference.
If you can accurately drill down the centre you can pick out the thread.
You can also weld a nut or washer then nut on to unwind the stud, the heat/cool can also help free it up.
