Title: Front disc bolt
Post by: uclabiker06 on February 06, 2010, 06:55:59 AM
Anyone know the torque value for the S2R front rotor bolts?  I couldn't find it in my manual.  Is 26NM correct?

24 nm, blue loctite.  26 is close enough.

don't get nuts and over torque by a bit - bigger isn't better - the stock steel is really easy to strip, so is stainless. Stupid allen head torque-out design. stupid stupid stupid stupid.

in other news, I had an opportunity present itself to replace my rotor bolts and went with torx head. low cap height, but torx head still.

Another good source of torque values for Ducs....

My 800 and 1000 both had torx head bolts stock. What did your 900 come with?

Standard hex. Never removed them until recently and they had gotten pretty stuck over the years. Had to drill a few out when the damn hex hole stripped out. I even went and purchased some new fangled hex wrenches to make sure the edges were nice and sharp.

but at least i did learn the glory of bolt-outs and got to replace with slick Ti bolts.

Although I do have Ti fork pinch bolts, I don't really see the value in titanium for the disc bolts.  I hate the torx bolts that came stock on my bike so at the advice of DuckStew I got chrome coated steel hex bolts that will fool a naked eye (into thinking they are Ti).

I've hear storied about how easy the oem torx bolts are to strip so I used a braker bar...didn't want to take any chances w/ those pos bolts.

 If you will use a hammer operated impact driver with either the torx or allen head cap screws (the correct terminology) you will have a lot fewer problems. Also do not use a torx or allen tool that looks used or damaged in any way. It also needs to fit snugly.

Even brand new allen tools aren't impervious to stripping. There's always a bit of luck involved if the bolt was ever overtorqued or has cold welded itself in. >:( stupid bolts.

Well, yeah, but you can always go w/ a blow dryer and heat it up.  I heard that works like a charm. Or a torch... haha!

I use a torch. Note: Heat around the bolt, not the bolt. You don't want the bolt to expand any. (heat also good to loosen up loctite).

if i dont care about the bolt, i always drill a hole into it, heat the core of the bolt for about 25 seconds and then hit it with an allen key.

THat was before i bought an impact gun. now i just beat the bolt into submission.
