Single Sided - Wheel Nut

[Gerry]

Same here guys .... end of ratchet cracked and snapped.... coz i had a long pipe attached for leverage ... Got it off in the end .. also the wheel was a bugger to get off because of a bit of dissimilar metal corrosion ... one year old bike! looked after and I don't think had seen rain.

I put some graphite grease on it when fitted the taper washer thing ....

how much for the Aldi compressor? is it ok kit?

I don't think it's something they usually stock. They do special offers on stuff sometimes and that week it was air tools. I paid about £85 for the compressor and £15 for the wrench. It's not bad stuff. When my large industrial compressor packed up a few weeks ago I ran 4 or 5 air tools non-stop all day off the compressor. It was running flat out for 8 hours a day, for 6 days and it survived.

Look guys, 176 nm means exactly that, if you dont put enough torque on then you are not stretching the spindle. Its the bolt stretch that imparts the friction to the two parts, not enough is no good. I still think that single sided swingarms on a road bike are a load of bull s**t, especially as I had to resort to power tools to remove the wheel nut like some of you others did. The other no no is the incorrect torque on the hub bearing clamp bolts, get this wrong either way can cause nasty problems with expensive remedies.

Dookbob is correct, the wheel is driven by the friction between it and the spindle flange, the required clamping force is calculated to achieve the necessary friction, this translates into the torque that needs to be applied to the nut.

Cor blimey, I'll assume the nut is 41mm then.............

176Nm is 17600 kg or 17.6 metric tonnes.

To put it into perspective medium sized nuts used for rock climbing take a load of around 9Nm or 900kg. This would mean they would take the weight of 4 Ducatis falling on them.

So 176Nm is some mighty force, just shows how much power is going through the back wheel at full tilt.

If you think I'm dropping 4 Ducati's on my medium sized nuts you've got another thing coming young man.

you sure - wouldn't climbing gear be rated for shock loading?

1 kg x 9.8m/s/s = 9.8N... so 176N = 176/9.8 =~ 18kg (40lb)

then 176Nm torque is the rotational force required to hold that 18kg weight stationary at the end of a 1 metre rod. or if you prefer, it's a (~3x bigger) weight of 130 lb at the end of a (~3x shorter)1 ft rod.

that's a 9 stone man standing on a 1 foot torque wrench - and if he does it to mine i'll hit him with it - especially as it only goes to 110Nm

Sorry I am talking borrox, climbing gear is rated in Kn, or kilonewtons. Which is totally different to Nm. Ignore me.
