Grinding from back wheel

Right so that 1/4 inch movement may well need to be even tighter.
Seemed to take up the slack though.
I'll know more when i road test it.

Be careful about over tightening the nut.

I undid mine with 3/4" ratchet and tightened up by hand without going to ridiculous extremes when I first did the brakes.

Next time I couldn't get the nut undone. I have a very good & expensive 650Nm whizzy impact gun. Didn't budge the castle nut, and I expected that it would simply impact it off.

Eventually I had to use a 7' steel pole over the 4/4 ratchet - thick wall because the normal ally bar was bending

I'm still confused about what happened, threads were clean and undamaged. The split pin will stop the nut slackening off.

By the way, the rear bearings in a T25 aren't taper bearings so they don't adjust like other vehicles http://forum.club8090.co.uk/viewtopic.p ... r#p8207550

The nut is supposed to be tightened to a torque of 500Nm then turned to the next slot before sticking the split pin in, which is roughly equivalent to 50kg load on the end of a one metre bar.

Weight of person in newtons (W)
11 stone = 685 newtons
12 stone = 747 newtons
13 stone = 809 newtons
14 stone = 871 newtons
15 stone = 934 newtons

Hub Nut Torque(HNT) is 542nm (400 ft lbs)

Distance = HNT ÷ W
E.g for a 12 stone person...
Distance = 542÷747 = 0.72

So if you stand on an extension pole(totally horizontal) 72cm away from the hub nut, you should produce the correct torque!
