Torque Wrench Questions....

[Grumpy Lee]

Could somebody explain in nice easy terms all the ins and outs of torque wrench specifications to me as I seem to have got confused trying to find out for myself.

What is there a difference between in.-lb and lbf.in?

Then there are N.m., Kgm and mKg, I presume these are different as well, is this where we are being metricated (or worse)?

Last question, I have just had a "sort out" and find I have two torque wrenches, one 0 to 80 ft-lbs and one 40 to180 lbf.in (4-20 N.m). Will these be sufficient to cover most jobs on my 1150, or do I get rid of them and get one that does the lot?

I, as usual, look forward to the helpful answers I hope to recieve as well as any general pi$$ taking without which these forums would be sooooooo boring

in lb stands for inch pound, and refers to the turning force applied.
lbf in stands for pound force - inch and is the same as an inch pound...
N.m stands for Newtons meter, and as you say is simply a metricated version of pound inch.
kg m and mkg are metre kilogramme and kilogramme metre (ie the same) and are a bastardisation of the metricated unit.

Roughly speaking 1 Nm = 10 kgm = 8.85 lbft

a conversion site is here... (click the torque tab)

sounds good, i think they should do most jobs on an 1150. possibly not the telelever ball joint.

a reversable one would be good if you have to do car tyres.

Any help?

The torques wrenches you have will cover a larger number of jobs on a 1200 engine so don't get rid and the figures will be similar to the 1150.

You can never have enough torque wrenches...unlike talking wenches.
Ouch, sorry Sarah....

One thing to bear in mind is after using a torque wrench you should always take the pressure off them ie unwind the spring tension otherwise it becomes weak and not give you a true torque setting.
