Does anyone know how to remove a stripped 4MM (grub screw) set screw out of a drive cup that is attached to my 2 speed transmission ?
I dont think theres a screw removal kit small enough ?

Best bet is you can try to heat the cup and it will melt the locktite, but you need to be careful you do not heat it too much and damage any of the trans parts or bearing, then you can try using a standard size allen key instead of a metric one, Or last resort is to drill the set screw and replace the drive cup. What car is the 2 speed on and is it just the normal cup or is it the brake disc cup?

It is on my tornado buggy and it is the drive cup on the opposite side of the one with the brake pad.

pm me you name and address and I will send you out a new one.

Old secret. Take a pc of paper and place over hole. insert wrench into screw through the paper. If you do it right the paper will act as shim on all sides around the wrench. You can go to any hardware store for a new screw.

Thats a good one! I have used a plastic parts bag before to do the same thing.
