Torque multiplier

[The Rusty Gear]

Anyone use a torque multiplier? I think they are intended for big railroad and oilfild-type stuff, and I was thinking they would be a great rusty bolt remover, but I recall reading that you shouldn't use a torque multiplier to break a bolt loose? ? ? ? at 1200 ft*lbs max torque, it would beat the snot out of my impact wrench

Yeah, I got a torque mutiplier..
It's 4 foot piece of metal plumbers pipe sitting in the corner of my shop.
Slip that over the handle of a 24" breaker bar and you can remove most crank bolts using your pinky finger pressing against the pipe...

Torque multipliers are 3/4" drive and above which would make them unhandy for the week-end or do-it-yourselfer. The smallest I have seen was 1/2" in and 3/4" out, but they get alot bigger. I have seen a 2" drive that was used on valves when I was in college. I have used one on axle housings and the spindles on our grain cart.

Used them when I was a jet mech in the air force. We used to remove and torque nuts.

I use one ocassionally to torque and loosen bearing bolts.They work well but are somewhat bulky and heavy.I would think that anything in the sizes most hoem or auto shop come across would be better removed using the BFH or Pipe handle extension method.

I usually use the "poormans impact wrench" on stuck bolts: a rubber mallet on the end of the wrench.
