Torque Multiplier

[del mar]

Afternoon,

Apart form the obvious, what does it do and how ?

I am looking to remove and obviously refit some centre lock wheels.

Thanks

The one I used worked on an epicyclic geartrain and was so easy to use , I undid 10 commercial vehicle wheel nuts with a 3/8 drive ratchet about 6 inches long in a matter of minutes no stress /pain etc the nuts where on a low loader trailer hub and had not been moved for years.This was a sales ploy by the way I was Snap on rep at the time , the boss of the transport business was so impressed he bought one immeadiatly cash on the barrel head ,if I remember correctly around £300 , cannot remember the part number but I am sure that they are still available google Snap on Tools . Care must be used when using them as it is very easy to shear or strip threads ,may I ask what vehicle you are working on? Hope this helps

A geared version of a lever with an offset pivot.
You move the lever a longer distance than the end delivering the force therefore your extra distance (let's say twice) is delivering a torque that is multiplied at the other end because the movement is half what you put in so the torque has to be twice what you put in.

I am going to put the original wheels back on.

I have the huge socket and a 2 ft long bar and a piece of scaffolding so semi confident I can get them off, but need to torque them back on.

A £300 tool is probably excellent quality but a bit lumpy for something I would rarely use.

Thanks

What torque do you need to achieve?

If I need to torque anything to a figure greater than I have a torque wrench for then i work out the distance to apply my full body weight at then stand on a scaffold tube at a measured point.

Yes it would probably be used once to get the wheels off!they ar generally used in commercial and perhaps marine applications so casual use foe wheel changes it over the top , do you know the correct torque figg and are the n/s wheel nuts left hand threaded take care !!!
