Thread: I bought a torque wrench

Not sure about the Discos, but the quickest way to warp a rotor on a Volvo is to rattle gun the wheel on and heat cycle the rotor. I know the Volvo is sensitive, but I assume it's the same for pretty much any car with discs.

True perhaps but NO ONE owns a volvo so its a non issue

Don't say that too soon! The Volvo drivers are back I see them everywhere now most of them are ****wits on the road.

Back to subject I think the alloy rim is less torque because of the chance of cracking the rim.

Dont think too hard about it all..... they are wheel nuts... round 140NM on anything is going to be fine.

There's a torque for almost everything whether you use it or not lol there's probably a torque for the spare wheel carrier nuts hahaha

There actually is.
If you look in the manual there is a 'correct' tension for every fastener.

If it's a non critical fastener I won't use a tension wrench but if it's something that could cause me grief if it either came loose or fractured I tend to use them.

And just a FWIW I have a study filed away somewhere where Ford fatigue life
tested rod bolts that were correctly, under and over tensioned.

Interestingly the under tensioned bolts failed well before the over and correctly tensioned bolts. IIRC it was something like half the life.

Alloys are usually less than steel and 130HD rims use a higher nut tension than stock steel rims.
The centre is thicker gauge steel so there is less distortion in the centre and requires a higher tension so the nuts don't come loose, somewhere between 120-130lb/ft.

To put it to rest this is from the D1 book. But with the exception to the HD rims

It does not put it to rest for me hahahahaa.

I have asked the same questions several times here without reply.

If the taper on the rims is different ie Dynamic rims will it require a different setting given the taper would increase the bite zone of the nut. Beyond the Alloy/Steel settings described above?

Also do people calibrate there torque wrenches as this is vital to getting torque correct. Just leaving it for one night not reset to 0 can blow out the calibration. I know i have done it several times.

I will confess i have NEVER calibrated a torque wrench.
