Torque Multiplier

[caver]

I have the Neiko larger unit listed in the first link. It's not rated for impact use and the ratio on it is slightly off per one of the reviews and they are correct. I've used a few times to torque/break loose rod caps in cylinder rebuilds on my backhoe.

I don't believe any of them are impact rated. All rated for manual force far as I know. Be too easy to apply too much twist with an impact tool.

My highest torque requirement - inner nuts on the tractor rear wheels - 225 foot pounds. That's a snap with my 3/4" breaker bar. My big torque wrench goes to 250# - so, tightening is no problem either.

Impact is not the solution for all stuck items. Sometimes you need slow steady MASSIVE force to break things loose or move them. I recall one good example where I was using a ball joint press (basically a giant C-clamp) to press out a ball joint on a front suspension arm of my wife's exploder several years back. I used the impact wrench (hi powered IR 1/2" one) and it would not budge. But even an 18" breaker bar with steady but serious force applied would move it. I have run into this multiple times over the years. I always start with impact as it is the Easy Button but there are cases where I know it isn't likely to work and am ready to move to a breaker bar and even possibly a pipe extension on it to get something to move. Just the voice of experience...

Fun fact is the OP just asked for a torque multiplier, without giving any details of why he need it in the first place, which is not needed anyway. As far as I know, an impact may not even work for the OP's situation or he simply wants to torque something a bit more carefully than just slam an impact on everything.

Darn! Another tool I need.

Ha ha! For a long time I know I've needed one (I've got stuff to un-stick things; I don't have things to tighten to spec anything over about 110 lbs-ft), and then I run across this thread and I feel ashamed... Need to figure out how I can order one of these things off of Amazon without my wife knowing (I use her account)!


BTW - The NEIKO PRO 3/4" is rated to 2,200 lbs-ft. That's hazardous duty category!

Interesting experiences for you. I have seen the opposite. I have broken lug bolts off when using a breaker bar. Frustrated, on the same wheel, I took the time to get my impact wrench. Got the rest off without breaking another and didn't grunt or sweat either.

I got some black iron pipe in plumbing section, 3ft sections 1" to 2" with adapters so I can use what's needed for the job.

Should be able to buy a multiplier on eBay at a decent price, haven't used my Proto for quite some time, not since cordless impact wrenches came out, some 1/2 inch cordless goes to 1200 ft.lbs.
