Yea I stripped one of the torx heads to day changing primary. I adjusted clutch a year or 2 ago, and foolishly thought the derby cover was allen bolts..Sucks getting old and hard to see, so I set motion todays failure by buggering the tox back then. I was able to get clutch adjusted and knew I would be in trouble in future. Future was today. Used mini grinder to score a straight across slot to get torx out. Question - are there better derby bolts out there, hex head or deeper allen? At least I was able to get 2 of the 3 holes changed today, primary and main oil. Tranny in near future. Another rant, have the Rineharts, WTF were the designers thinking on that rear down pipe, impossible to get to oil and tranny filler..May be time for new set of pipes as well.

I haven't had any issues with mine, but I do torque them with a torque wrench and I put anti-sieze on them before I reinstall them.

I have heard of several people using chrome allen-head bolts.

I did the same a few years ago. I took the lil torx bolts to home depot and bought stainless allen bolts for a few bucks and haven't had any problems since

But they aren't stamped HD, won't that void my already expired warranty

Thanks, I see a Homedepot or Lowes trip in my near future.

They say torx head has more Sq area to grab than Allen head. (On paper). Damn Engineers!
The dealer has replacement chrome Allen head. One of the first things I changed on my bike.

You could spend a few more bucks and get ARP 12pt stainless.

The most common reason that people strip out torx head bolts is because they use inferior or the wrong size tool. The primary uses a T27 a lot of people use a T25 because most torx sets don't include a 27 they go from T25 to T30. The T25 for the most part fits and will loosen/tighten the fitting but after a couple torque sequences will strip out.

Not saying this is what the OP did but it is a pretty common occurrence.

I'll have to forward your response to Barnett HD in El Paso. Their shop must not have the appropriate tools to work on bikes. They stripped mine and a friends when doing a service.

OP stupidly tried using an allen wrench cause he assumed they were allens. Too old and lazy to lay on ground and get a good look at bolt type (again I assumed WRONG)..Once I mangled the first one up I realized they were torx, I have a 27. First time derby cover off, assume assembly line cranks them on good. I now own a shop manual, someday I'll get a lift.

I have witnessed a dealership tech reinstalling primary cover screws with a cordless impact. Hence the reason I service my own bike and use a torque wrench.

Ace or True Value hardware stores have a good hardware selection. I replaced mine with stainless allen bolts but I know you can get chrome allen bolts at Ace.

Had the same issue with the first service that I did on my own. My Indy shop used a power tool to re-install and used a T25 head. Last time he has worked on my bike. I bought the chrome replacements from Harley and have had no issues since.

 

[danglide]

for those interested,the derby cover bolts are 1/4-20 x5/8.ACE has chrome button head allen bolts.Just replaced mine for one that was beginning to strip.
