RE: Hex head screw removal
Once removed, replace it with a torx. Standard on newer models and much less prone to stripping. If others find themselves in the same predicament, use a small sharp chisel and try to move the bolt head in the direction of loosen as rh8234 mentioned above, or if you are unwilling to try that, I will hammer a torx into the hex bore and try that.

RE: Hex head screw removal
In my opinion Torx heads are worse. I had problems with Torx head screws. Thats why I switched to hex. I even ruined the Torx socket. No matter what kind of screws you use, I recommend replacing them with new ones everytime you remove the derby cover to change the gear oil.

The dirby cover, hand controlls and a lot of other servicable torx bolts are #27. Get the right size and your life will be much easier/
It's all in the DIY in the proper area under transmission/clutch and primary related

RE: Hex head screw removal
When you break a tap off in a bolt, you then have to deal with the rockwell hardness of tool steel. The best way to remove the problem bolt at this point is to use a tiny carbide bit (1/8") shaft, with a small round head. It's best if you have an air die grinder, but a dremel tool will work, just slower. Just grind the head of the bolt completely off, remove the cover, and remove the headless bolt with vise grip pliers.

RE: Hex head screw removal
Bob53.... Try this when you put in the new hardware...
Anti-sieze the threads on the screws before you install them.
5k later, when you are servicing the primary, take a T-27 socket and rap it with a hammer (Just not hard enough to break the cover or primary), then unscrew it. Works like a champ.
Any one else that has a hard time getting them out, use a little heat and a hand impact to break them loose....

It always helps to use a little prevention when replacing any screws or bolts. After removing run a bottom tap in the hole to clean it up. This is a must after you remove the factory stock screws with the sealer on the threads and are replacing them with new.

RE: Hex head screw removal
I might have been a little hasty in recommending a tap for cleaning threads. Use only if no other tool is available. The best method is to use a restorer or a chaser if you have them available. These are configured to only remove nick, burrs and restore threads without removing metal and making the hole loose. I'm glad that I corrected myself before I got beat up by the sharpies.
