Had a pretty good weekend...  More work to do, but we're getting there.

Great report Jeff!!!  Cant wait to get out there and mix it up with you guys!!!!!! ;D

[Jeff]

Thanks man...  Looking forward to meeting you as well.

[Thingy]

That sucks about the axle.  We had that happen one time to Knuppy's GSX-R the year that I crewed for him at the AMA's.  We had to grind it off.  I still don't have a good reason why that happens.  I guess the threads can only be tourqed so many times.   ???

[HAWK]

Do you know what material the axle is made from?  Some materials like Stainless or Titanium are very prone to galling without the proper type of anti-seize compound. Just a thought.

[Jeff]

Hell, I don't know.  It's made of metal...  LOL.

I have used the same axle on a honda for 4+ years and probably +100 wheel changes and never encountered this before.  But I've seen it on other items, so I knew it was possible.

Such is life...  We got through the day and have a new axle on order.

Dunno about using anti-seize on the axle nut.  Will it affect torque?

The Honda setup is not the easiest to effectively pin or wire.

[HAWK]

Using anti-sieze will increase the effect of the torque, more clamp-up for the same torque but at the same time make it easier for the nut to loosen by itself. Of course that also means it will be less likely to damage the threads on dis-assembly. Looking at the pictures you posted on your page I am going to assume (always dangerous I know) that the nut end of the axle looks similar to the head end and you could drill the corners and do something like this....


The way the mfgs are trying to lighten these bikes you never know what you are going to run into material wise, and while some materials simply cannot be assembled without anti-sieze I can't see how using it could ever be a bad thing especially when you consider that you will probably remove that axle more times in a season that the average Joe will in a lifetime. I would recommend determining the material first though since there are many types of anti-sieze and some are more suited to certain materials than others.

Is the axle magnetic?

[Jeff]

Axle isn't magnetic, and the end you see there is from the 03 axle.  The 05, on that side will be recessed into the axle block, and then out the other side to a nut..    I could drill it, but for whatever reason, that particular bolt is a BITCH to drill out.

Got my new axle, nut, block & washer today. 

I'll be using moly anti-sieze as well...

For drilling I have found a place local to me that sells repointed carbide drill bits. I buy the 1/16" bits in a 10 pack for about $20 and use a drill press. They are solid carbide and cut anything like butter. http://www.store.yahoo.com/drillcity/116.html

BTW being non magnetic and very dificult to drill kinda says titanium (still a guess though) and titanium is VERY prone to galling like that.

[zoner]

The axle is aluminum, a small dab of a good quality grease, or anti-seize would be a good idea to prevent galling.

[Jeff]

to back up a couple inches, the axle IS magnetic.  Just had a super weak fridge magnet through plastic that wasn't sticking well.

The tough part to drill is the NUT.  That bitch is hardened like nothing else.

They are definitely 2 different metals which would assist in galling, so anti-sieze will be a good idea I think.

[HAWK]

Back to the link I sent you, those carbide drill bits are fantastic. Just be sure to use a drill press, carbide is like glass, if you bend it at all they shatter. I have both covan (gold colored bits) and the carbides, the carbides cut about 10 times better than the covans and are the only bits I have ever seen cut a 10" spiral shaving with a 1/16" drill.
