frozen torx on derby cover

hi. can anyone help me out? im trying to remove the derby cover from the primary cover and the torx are frozen in. can i use a small torch to try to expand the cover? Will it damage the chrome or the covers?

Anything else i can try without resoprting to a torch?

Thanks

paul

Try a Dremel...

Sometimes I use a Dremel with a small cutting wheel to grind a slot in the head of a siezed bolt that has its drive feature stripped. Then you can use a flathead screw driver to remove the bolt. The deeper you can grind the better (without getting into the cover). That way you can use a wider screw driver and apply more torque to the bolt. You will want to get new screws afterwards.

Did this last just last week to 3 stripped button head cap screws.

Frozen torx

A valuable tool I've used many times is a simple impact driver. It works great as long as the head isn't stripped out. An inexpensive one only costs around $20.00. Just use a Torx socket and a hammer to release it, then it should come right out. I would stay away from heat. It will likely blue the chrome. I would also replace the ones that are frozen. They may have been overtightened and could break the next time you have to remove them. Let us know how you make out.

Good Luck!

just drill the head off with the right size drill and then use visegrips worked for me.

Torque me off dude.

I swear H-D uses grade -2 hardware some times. They also use Torx PLUS hardware and not regular Torx sizes. That is the reason most of these get stripped out. You will either need to get the correct Torx plus socket or better yet, get rid of that OE crap and go with some good quality button heads.
