Anybody tried to take off there derby cover on the 11 cvo? Did my own 1600km (1K) service the other day, drained all three oils and went to remove the derby cover to fill it up and the stupid torx head screws were so freakin tight that only one came loose and the head of the other four stripped out. No I wasn't using cheap tools but quality snap-on torx socket. Ended up having to drill the heads and use a screw extactor on them. Made me very nervous to drill on a chrome cover with only 1600 km. Just wondering.

The automotive industry invented Torx screws because they can be installed faster than allen head screws...and because it is easier (cheaper) to install them in an automated process.  They are not used because they are better.  They are used because they are cheaper to assemble. 

Throw them away and install allen head screws.  You'll be glad you did the next time you have to remove the derby cover.

Not an unheard of problem; you used a T27, correct?  I ask only because some sets don't include the T27 and a T25 is used instead with the same result--rounded out heads.

No fear on using the wrong size went and bought the right size the day before. Just cheap screws. NEVER had this happen before even using an L torx T27

FYI it would be a great idea to "check all fastners". I found some that were about to fall out and some that were over torqued.

That EXACTLY same thing that happened to me on my '08.  I cussed for a week having to go get Easy-Out tools to remove these screws.  I replaced the Torx with S.S. socket head cap screws.

oldog, removing the clutch cover screws has always been a pet pev of mine. I do it every day for a living. menny hand heavy "techs" think thay have to over tighten the screws when a lite touch or proper torque works fine. to lock tite those screws is a sin and who ever does that should have there tools welded together and pushed off a peir in
deep salt water.. I suggest anti seize in the hole and then torque to spec. and the torx button head screw is so much better then the allan butten screw, allens strip out way too easy. this is the motorcycle industry.

OlDog, I had almost the  same problem. When I did my 5K service on my 09 SEUC a few of them were pretty hard to get out and at least two of them made this wierd snapping sound when they broke loose. I had a 1K service at the dealer so I assume they tightened them too much. Nothing broke and nothing stripped but it still was an irritation. And like one of the other guys on the thread mentioned I too have found a lot of things just barely tight enough and some things too tight.CAHDBIKER

Did a check on as many fasteners as I could get they all seemed ok. I did find a loose nut on my backrest bracket...my fault. Our dealership here GAHD does really well on the pdi, so no complaints with them.

This little gizmo works for me, I bought a quality set of bits for it and if a screw of any kind gives me difficulty one good smack loosens things up, I have been using similar tools on Metric engine cases since the 50's http://www.harborfreight.com/impact-screwdriver-set-with-case-37530.html

    Right on the money.  The fault lies with overtightening and thread corrosion, not the strength of the screw heads.  I had the same problem the first time I cracked mine loose in 2005, had to replace a couple screws, but have not had a single issue with them in the subsequent 6 years.  I always install with a torque wrench, and a very light film of antiseize on the threads helps that dissimilar metal corrosion problem that acts like a thread locker.  NEVER use thread locker on this stuff.

I have been replacing my fasteners since I got my ride...most of mine were heavily oxidized...I use a small impactor made by Bosch to take them off...works great, no stripping yet...and some of mine were nasty dirty etc...

I use an inch pound torque wrench to put back on...Haven't got to taking off my exhaust yet to get to the rest of the right side yet!!

Went with SS and they look great.

One investment I made when I purchased my first Harley was good ft-lbs and an in-lbs torque wrenches.  I try and torque to spec when I can.  From my experience, most HD techs use the old it feels right approach.  When I try the same, I find that I way over torque.

Next investment is a torque wrench for the 1-40 in-lbs range.

I had the same problem with my clutch cover on my '06 and my '10. Lucky for me the ones on the '11 came out fairly easy. One out of three ...not good odds.........

My problem wasn't rounded out heads ( I have a T27); I literally broke the entire head of the screw off the shank.
