Wheel Bolts
 

So I wont be using My Tourer for a few days. I thought I would take the wheels off and give them a good clean. Now for some advice please, when I but the wheels back on would it be a good idea to but some coppergrease on the bolts.
I know that the Torque as to be 125Nm, but dont know if I should use coppergrease. :confused:

no copper grease and no lubricant, they go on dry

Thanks for your quick reply. Thought they did , but it was just a thought,


Cheers and keep well

I always smear a little coppaslip on bolts.:cool: And between wheel and hub:cool:

coppaslip here too:shrug:

NEVER lubricate the bolts. It's the FRICTION that keep them done up tight.

You will never find that the wheel bolts need lubricating in any service manual.

You might even find yourself saying---Oh look, a wheel has just rolled past us ---only to find it was yours---:eek::eek::eek:

Someone did mention I think on a bike forum how "copper slip" can lead to over tightening.

Hold a heavy metal rod vertically in your hand, feel how hard you have to grip to stop it sliding through.
Now "copper slip" it and try again, see how hard you have to grip :)

I bet the pressure on your fingers is greater with "copper slip"

I have always used coppaslip and never lost a bolt?!?

Must admit that this link from T-Cut https://www.engineeringtoolbox.com/t...ts-d_1693.html got me thinking as I, like most others, use a form of copper grease so I tried using the torque wrench with the copper grease - took a lot of effort before I heard the set click, and then relieved the pressure, and put them on as I've always done by feel - most of the times I use my airgun, but even so I usually go around and double check with a socket and bar.

this I understand
Note that if torque specified for a dry or slightly oiled bolt torque is applied to a lubricated bolt - the bolt may overload and break.

this I don't
When a bolt is lubricated - less torque is required to achieve bolt axial load or tension. Reduction of torques for lubricated vs. dry bolts are indicated in the table below
