Thread: D2 stake nut - rear axle

When I did mine I used a 1.5 m cheater bar on the end of a ratchet and bounced on it till I thought it was tight enough, 25000 ks and still ok.
Might not be the correct procedure, but it's bloody tight.

hello Yorkie. i purchased a second hand Warren & Brown torque wrench rated to 400Nm for $200 from cash converters. they are $400 new. Repco used to sell them. this brand are the best to buy as you dont need to calibrate them. if you plan on doing work on your own vehicle a torque wrench is a sound investment. Even if you change your own wheels you should torque up your wheel nuts to 120Nm. if you do decide to buy a wrench dont purchase cheapies from the auto retailers as they sell the dial units which go out of calibration easily, generally rated to 200Nm for $70.

360 Nm is approx 36kg on a 1 m lever (36.7kg if you want to be a bit closer)

High school physics will save you the best part of $400 as you could get away with a spring balance and a suitable lever. In case you don't know

Nm or Newton metre is a measure of torque, a Newton is a measure of force (named after Isaac Newton, the guy that watched and wondered as the apple fell from a tree). Force is calculated as mass by acceleration. Acceleration is the value of gravity on Earth in this case i.e., 9.8 m/(sec^2)

F=ma where F = force in Newton, m = mass in kg and a = acceleration in meters/(sec^2)

Torque = Force x length, where Torque is in Newton.meters aand length is in metres (i.e. the length of the lever)

T = F x l or 360 Nm = 36.7 kg x 9.8 m/s^2 x 1m or

? kg = 360/(9.8 x Length)

so for a 450 mm breaker bar where you could hook your spring balance up about 50 mm from the end of the bar.

360/(9.8 x 0.4) = 91.8 kg (reading on the spring balance)

And if the maths and mucking around of using a spring balance does your head in get a torque wrench.

dswatts,

with a lever at 1.5 m or about 1.4 or 1.45 allowing for a hand hold on your cheater bar and your 75 kg on the end of it (75 x 9.8x 1.4 > 1000 Nm) will give you heaps more than your target 360 Nm that is why it is still holding after 25000 km.

thanks to the replies above ^^^
with my slender frame and 2mtr piece of pipe i should not have an issue then.
order the bits and will try undoing the nut tonight to get the ball rolling.

just dont do it on a ratchet.... Use a very strong breaker bar and preferably an impact socket.

Think I need a stronger breaker bar!.



That's a kinchrome extend bar totally sheared off!.

Did you do both the extension and the breaker bar? I see three pieces.

I kept an eye out for a 3/4" breaker bar and bought one on e-bay and have picked up the odd socket as they come up.

Been there and done that. I ended up borrowing an electric rattle gun from a bloke who has earth moving equipment. It was sickening how easy it did it after having gone down the same road you have just gone down.
