Evil sodding rotor bolts.

Enid_Puceflange · Sep 21, 2012

File a slot in the head of the bolt to allow you to get a screwdriver in there,
Then before attempting to job with real force,
Get the kettle boiled and pour some water over the bolts
It should help break the thread lock as the hubs aluminium will expand a little bit more than the steel bolts
Has worked for me every time I use it

GOODLUCK

I think they are steel so are a pain when the Hulk does them up. Even getting a slot in them can be tricky.

The boiling water trick has got to be worth a punt before breaking out the Black and Decker.

Thanks gents, top advice. Off to the diy shop tomorrow for a file, and give that a go with the boiling water nefore I start drilling.

Cheers

If you do decide to drill, I'd use a fairly large drill that will only drill the bolt head. This way you will have the maximum amount of stud left to get your Mole Grips on.

I had the rounded torx head problem. I drilled the head just enough to get a flat bladed screwdriver into it and then a couple of short sharp taps with a small hammer on the screwdriver to get it to bite. Then simply turn the screwdriver and out comes the bolt sweet as you like.

This method is very good

If I find a rotor bolt that's stubborn & I've not rounded it off I'll go straight for the kettle & make a cup of tea

oh and use some of the hot water to soften the threadlock

Then they're much easier

If the head is rounded off, it's cut a slot time & use a screwdriver. I like the ones that have a hexagonal part to the shaft as you can use a spanner on it to turn the screwdriver whilst applying maximum downward pressure on the screwdriver to stop it slipping out of the slot you've cut

Then it's drill the little *@!$*? out if all else fails..

I had this exact same problem a couple of weeks ago.

The bolts were torx (T25), and I managed to round one of them off using my T25 tool.

I swapped my T25 tool for a better quality one (Sealey, from memory), and it managed to find some purchase on whatever was left of the bolt heads, and the bolt came out easily.

What I'm saying is that it might simply be worth trying a good quality T25 tool before going down other avenues, as you could save yourself a lot of hassle

if you are able to support the rear of the bolt holes - I suspect not - then an impact driver would help - this is basically a tool that has a ratchet that you hit with a hammer, when hit, it will turn - the idea being that it will not slip in the bolt head.

if you end uo having to drill the bolts out - good luck - it isn't going to be easy.

Got all the bits lined up, gonna have a crack at them tomorrow.

And they're off ! about a gallon of boiling water and a good twatting with the impact driver and they're out, had to do 3 on one wheel and 4 on the other, threads absolutely covered in locktite blue.
Thanks for all the sparklingly great advice.
