A question of torque....

DIFFLOCK66 · Jul 20, 2014

So, the D2 hub's stake nut requires plenty of torque - 362 lbft according to the haynes manual. Just double checking if I've got the maths right after successfully fitting a new hub

At a distance of 1 foot away from the nut, there needs to be a force of 362 lb.

Therefore 2 feet away the value is halved: 181 lbs

Therefore my 189 lb weight will do the job at the end of the breaker bar, yes?

Especially if the bar doesn't move despite me bouncing on it :faint2:

EDIT - THIS IS TO TIGHTEN THE NUT UP.

at two feet the value of torque applied on the nut remains the same but the input required to get the output value halves so in theory yes it should work but depending on the length of your breaker bar you may end up over doing it

however as its after 12am and I am partly ****ed I take no responsibility for not engaging the physics section of my brain......if I'm wrong ask me again around 11am and it may have restarted itself

be careful , with a 3-4 feet bar its easy for my 11 stone to do 550lbsft with an 1 and a half ft extension on ( using inch drive)

for the torque setting your doing id recommend you use 3/4 drive tools

That's a lot of torque though your theory is perfectly correct in my eyes.

That's what size drive I'm using: 3/4"

The breaker bar is a couple of feet long.
