95000 miles, same bolts as when I bought it new.

 

Yes this is easy. At the onset with little bit of panic and it looks all bad but this is really easy to do.

 

You think you got problems, OP? Lemme tellya my sad tale! When I was installing my derby recently, I used a Torx security bit...the one designed to fit over the Torx with a post in the middle...like a buffoon! That bit snapped right off...and it's still in there...and its hardened steel...and there's no room to cut a slot on the head so's I can use a flat head screwdriver.

Ah, well. That's a problem for another day...like when it's time to change the primary fluid. But for the nonce...I ride!

Might be able to tap hard around the head of the worthless Torx fastener to get that bit to fall out when the time comes. Or use a couple of other old school tricks to back that puppy out. Or...maybe it's already fallen out.

​​​​​​​And the hell of it all? I have a good supply of Allen heads that I coulda used instead! But NOOOOOO... I HAD to use them pointless Torx!

 

I have pulled 20000+ derby cover screws and never stripped a single one! Ive seen plenty that where already f'd up and took appropriate measures to remove them without stripping tbem. Good quality snap on or matco bits and a 3/8" air cat takes them out all day long!

You guys that think SS allens are better are severely mistaken...good news though, when you strip them you can hammer a torx driver in and back them right out

 

Hogdoc, you be right about them Allens! Especially when you use a ball end tool! As you say, the correct tool is the key...a lot of those Allens have a bit of a chamfer, to make 'em pretty. Will cause ya a problem if ya don't get a good bite on them!

​​​​​​​That said, I still hate Torx! Just because! They were the answer to a question never asked. ..in my opinion, of course!

 

Good fit with the torx driver, a dab of anti seize on the threads from time to time, DO NOT OVER TIGHTEN, they will last forever. Never a leak, never a problem.
When they "Pop" loudly when you remove them, they are probably too tight.
Personally, I like the way the original torx seat flush with the cover, where most allens will protrude from the cover. That's my .02...

 

Very common problem, & the first time I changed the primary fluid I stripped 2 of them. Since then, every time I have to remove a torx bolt or screw, I replace it with an allen head.

 

Every chance I get I pull them out & go back
with SS button head . They look better & no
worries about rust .

 

one thing I've noticed is it's almost always the last one or two that are stuck. What I've done is put another back in across from the stuck screw and tighten it down. that seems to lesson the pressure on the stuck one.

That being said I've had to drill one or two out as well. When they are out I always use antisieze.

I hope this helps.

 

Stainless bolts I into aluminum can be problems too. Always use a little Never Seize.
