Torque Multiplier

[Dave5Cs]

Ok I did it. I bought the cheap "Torque Multiplier" because i have to pull some of my wheels to get to things. It looks decent for $160.00, 60:1 ratio.

The only part I had a hard time with is i don't think it is good for torquing them back on to 500 ft lbs because i didn't see a ft/lb set adjustment. But is a whole lot less than 600.00. I am game. Anybody else use this tool. Got it on E-Bay.

It looks like the same one I have.  Works fine.  I lean my weight, about 140# into a three foot bar to re-torque to an estimated 450#.

[Dave5Cs]

Lin, so I am right , there is no setting for re-torquing then? I am 240lbs 6 ft tall so I use what length of pipe on a 3/4" drive breaker bar to reach 500 Ft Lbs? or do I just set my HF 1 inch air impact for 500 ft lbs and let er rip?

If you trust the setting on the air impact, that would seem fine.  Otherwise, your 240# on the end of a 2 foot lever should give 480 ft/lbs, right?

I have the yellow one that is 78:1 ratio - but essentially the same thing. It is for removing nuts that were either put on too tight or nuts that have rusted on. If you use it to put them on, a little bit of error on the input will be huge on the output ( at a 60 to 1 ratio, a 5 ft*lb error on the input = a 300ft*lb error on the output ).

For reinstalling, I use a 5 foot bar while standing on a bathroom scale - push down or pull up till the scale shows 100 # difference & you are at 500 foot pounds of torque. If you bounce on the pull handle, your body inertia can drastically increase the applied torque.

Ok if you hook a 3/8 or 1/2 drive torque wrench with drive reducers to the multiplier 60:1 = 1ft/lb.

So 8.3 ft lbs X 60= 498 ft/lbs on T wrench.

Les Marston, figured that out and I think it will work fine.

Well I received it in the Mail today from UPS and it is pretty neat with all the sockets in a nice small plastic case. It works well for taking off the nuts both outside and inside. I think the end of the handle that goes on the end to turn the outer end is a little thin for the operation. Might make my own or mark one out and ready to cut out. Other than that i think this will work very well and is controllable. If you go slow and careful with a small torque wrench to the end I believe it can be done with out destroying a stud or 2.

Dave,

I contemplated that concept (using torque wrench through the device) but was not sure it would be to dependable.  I worried it would be too easy to leave it too lose or tighten to much, so I am sticking with my weight on a bar.

[Dave5Cs]

Lin just doing a little experimenting. I do have a 3/4" torque wrench I can put a 4 foot bar on but want to see if it works using the tool too. 8.3ft/lbs X 60 = 498ft/lbs.
