Problem, got an idea for a solution?
« on: April 01, 2009, 07:03:03 AM »
Ok.  I have a super expensive snooty XTR hubs with Stans Arch/ZTR 29er wheelset.
Love the doggone things with the Centerlock rotors and such.

BUT, its the wheelset that is normally dedicated to my "race bike", that soon will be built...LOL..

Regardless, I have a DT swiss with an ZTR rim that I use for my beater bike and in the process of removing the abnormally large front disc that I had on the XTR to the DT swiss, I found 2 of the rotor bolts that are stripped out.  I bought a bigger torx head, 2 of them and they still wont come off.

Any ideas of possible solutions?

thanks,
Karlos

Might try vise grips gripping on the sides of the bolts.

it is a tool similar too a drill bit that bites into the center of the bolt once predrilled and spins the bolt out. i had the same issue on one of my kings and CAREFULLY drilled it out.

EZ out is an extractor that is LH thread, but I don't think it'll work here. What you need is one of those screw extractors that will bite into the stripped portion of your torx screw. They should have them at Lowes or a similar store.

kind of like a reversed drill bit.  It will dig into the bolt and remove it. without retapping the hole.

Option #1 Had the same issue a few years back and the vise grip solution didn't work for me until I hit the head of the screw/bolt with a hammer (not to hard now as some flanges are pretty thin). May even install the torx driver and hit the drive end with a hammer as it will focus more on the center of the screw.
 
Option #2 Sometimes you can drive a flat blade screwdriver into the torx pattern (you'll have to have a good assortment of screwdrivers though) and then back it out just like  screw.
 
Option #3 Another idea is to grind/cut a slot in the head of the screw with a die grinder cut off wheel (like body shops have) or a hack saw and then us a flat blade screwdriver to remove.
 
Option #4  Last resort is to apply heat (torch) to the head of the screw very quickly but keeping in mind that there are seals in the hub. When the screw cools down it may come out using your fingers as the tool, unless threadlock was used during assembly. Heat helps break this down a bit though. Not sure how safe this procedure is on a hub but when I've done it on other things it was necessary to get the bolt/screw cherry red with the torch.
 
Option #5 Not sure if they sell them in very small sizes but can try those special sockets meant to remover rounded/damaged hex bolts. Sears sells them but may have to buy a set $$$$

+1 pretty sure Sears carries these as well.

First thing to do is spray it with liquid wrench. Then proceed with other options.

I've found that PB Blaster works better, may not be as readly available as LW

I was gonna suggest smacking it with a hammer also, have to be careful though because the hub is aluminum like Catman said.
 
Oh, and Aerocroil is better than all the penetrating oils! ;D
