BDCW standstand relocater broken bolt

[FakeName]

A quck search cannot locate a 10 x 180mm bolt above metric grade 8.8 (5). I have my bike on the rack right now, just installed a relocator and a bash plate- it'd be SO EASY just to replace the bolt in question.

Alas....

I go to a metric land (Aus) next week for a 6 weeks or so, I am sure I can find one there.

When it broke it just let go with a bang. I could even find the end with the nut on it.

Fastenal has several M10x1.5x180 hex head listed. Grade 10.9 (SAE 8). Also threaded rod in grade 10.9, but only in 1m lengths.
Grainger has a socket head M10 Grade 12.9...$23.61 for pack of 5. item number 6CU50

Thanks for the heads up...will be keeping an eye on mine, or if you order a pack I would gladly buy a couple from you.

Well the BDCW guys have offered to replace the bolt. Very, very good of them. Not what I expected or requested. Especially as I said in the first post, that I don't consider the breakage to be a product fault.

Great guys.

[what car??]

Best solution of them all that I{ve read, get a CJ Designs side stand relocator. Burly and does not involve the engine bolts at all. Best design out there!!!

Best design is on the 950RR.

Correct.

Why?, all it offers is a higher sheer strength which is what Craig is looking at, I can't see why that would be a bad thing as it will cause no other trouble.

Because it’s the flexing of the plate acting on the bolt, not the bolts lateral strength. Think iron vs steel.

Yep. Bust bolt, replace. Irrespective of material hardness the bolt will be under the same tension, harder steel is more susceptible to bend fatigue, but is also more resistant to bend. It’s all a compromise, the KTM design is stupid hence look at the 950RR. Its side stand is welded to the frame.

Would you like more elastic with that story .. a little over the top comparison.

How about bolt done up properly with no flex allowed between casings, mounts and bolts, I little less dramatic.

Two moto Kiwis,

I would think that with all the trouble you've had with your new KTM, you wouldn't be so quick to dismiss this. If you break a case, as many have, we don't want to hear that it was the fault of the seller or improper installation.

Cool with that and not dismissing anything, but it has to be kept in perspective too.

I am not dismissing anything as we have the same kit on ours so my eyes are open but from an engineering perspective a nice snug bolt that takes out any amount of flex is not a bad thing, not trying to upset anyone (which seems to be easy here for some reason) just keep it in perspective.

As noted above, everything is a compromise so nothing it perfect and it doesn't matter who makes what there is usually room for improvement and this only comes from gear being used in the field.

Great news BDCW stepped up to offer Craig a new bolt, excellent service to say the least

I don’t think you’re getting it; the long bolt goes through the two halves of the engine cases with the paper gasket that sits in-between. You can put a super high tensile bolt in, above 12.9 and torque it up as much as you want, result will overload on the ally parts which will cause damage, with the inevitable loads it will fail and go off like bullet.

Tighten the wheel bolts on your car to 4x the recommended torque; the bolts will take that load stationary with no problem. Start driving like that and the wheels will snap the studs off and pass you on the road.

Actually I get it totally, I am not saying over torque it at all .... NOT once have I suggested that FFS and yes I know where it goes.

I won't bother any more, you seem to want to belittle anything I say so yeap it is all yours ... hope you are happy now.

Craig sorry your thread turned into a pissing match of others trying to twist my words and make suggestion of me trying to do you wrong.
