Torque Conversion

[pensioner]

The Info plate on the side of my van (Lunar Cosmos 352 ) says the torque for the wheel nuts on alloy should be 115NM.
My torque wrench only has Ft/Lb or M/Kg
.
Is my conversion to 85 Ft/Lbs correct please. :S

 

[xtrailman]

Yes its correct.
I always use online conversion for things like this, just google nm to ---

Yes, as near as damn it, to be precise its 84.816 but 85 will do. Just to remind you that after you have torgued them up don't forget to recheck after about an hour and half run, and always check them from time to time and do not over tighten or use grease on the studs/bolts.

Thanks folks,,that's re-assuring,,,daft thing of course is that the spare is a steel wheel so the torque for that'll be different but at least I know my maths were close.

On some types of wheels depending on the manufacturer the wheel bolts are different. Steel wheels normally use a conical wheel bolt the torque setting's are also different ...

If I remember rightly the bots for alloy wheels are longer than the steel ones, I have a set of five bolts for use with the steel spare wheel that stay in the van. It worthwhile checking before you venture out.

 

[pensioner]

Yes,,when I collected the van there was a set of 5 wheel nuts, so I'm assuming they will be for the steel spare.

I have alloys on my trike and had to buy special bolts with built on washers to avoid damaging the wheels.

Just a heads up, if you have smart phones, look for an app called ConvertPad

Be wary about any conversion program of getting the units the wrong way round !!

 

[Thingy]

Absolutely, have a look and check it out yourselves. Its just a heads up, if you feel its useful, its done some good.

Im nothing to do with it, its just that i have used it for years.

Forgot to warn you, under no circumstances would i use a Joe Bloggs torque wrench ie.one that is obviously old and been abused. They could give an incorrect reading with dire results. When I was in engineering, our torque wrenches, pressure gauges etc had to be tested and recalibrated or disposed of.

For round figures so making it easy to remember, the ftlbs figure is a quarter less than Nm, so divide Nm by 4 and times 3 is quite close enough in ftlbs for our purposes.
