Hand Turn 5,000ft-lbs?! $60 vs $4,000 Torque Multiplier

Are the hand operated torque multipliers we see from time to time ACTUALLY multiplying torque like they say. Sure you might have to spin it 64 times in one end to get 1 turn out, but does that mean it's really multiplying things 64 times? What about tools with an advertised torque ratio, is it useful to use a torque wrench in to get a certain value out using that figure? Are the cracy prices at the top justified? Today we aim to find out by testing an Amazon option like NEIKO PRO 03715B vs the likes of USA Snap-On, Wright Tools and more.

If this comment gets a single like from anyone we'll buy more torque multipliers, these were stupid fun

[thegreatchickenoverlord]

Now we gotta allow the good idea fairy to provide a visit, and drive a torque multiplier with a torque multiplier

Finally found what Jiffy Lube uses to tighten drain plugs .

[letsgetsteve]

So that chain is an incredibly dangerous spring, and if you guys do this again, please, use a solid, noncompressable stop for holding the reaction arm. As a Millwright in a steel mill, when torque like this goes wrong with sprung restraints, people can die. I have seen stuff go straight through cinderblock walls. Be safe.

I can't believe the first one you opened even works. Sand cast gears... amazing.

"Anyways, here's us using an impact wrench."😂😂😂

[benst]

If you stack all of these together you might be able to remove a Honda crank bolt.

The $4k Wright multiplier is really handy to use with a pneumatic nutrunner. Ours is a 25:1 ratio, and with an Ingersoll Rand 9RSQ83 nutrunner, it's 300 rpm & 82 inch-pounds input, 12 rpm & 170 ft-lbs out. Moves stuff quickly.

[jmargarson]

What would happen if you connected the output of one multiplier to the input to the next? Chain all the multipliers and you'll be able to twist spacetime.

A couple of us broke 2 $13k torque multipliers one night trying to remove die bed bolts. They wouldn't let us cut the bolts, cuz they were special order, until they saw the 2 broken multipliers. lol

I work in a hydraulic cylinder manufacturing plant, we use electric motor driven torque multipliers for the piston nuts, crazy how tight they can get accurately

[elliotkane]

We use generally hydraulic or electric versions of these in structural steel to do final torque, after snugging large or particularly important bolts we will go either 1/3rd or 1/2 a turn (depending on bolt length) to reach final torque, this is what we do on roadway gantries, large road signs, refineries, tunnels, mining equipment, etc.
I worked at an ethylene-oxide plant one time using a hydraulic torque multiplier to break loose the bolts holding the catalytic chamber together.
Huge bolts, about 70 or 90 or so of them and they had to be cracked loose 8 at a time - so hydraulics running to 8 reaction arms.

It was a major job, took days for a dozen guys just to do that.

[HonzaLancer]

As a semi truck driver i can say these things are priceless. Recently i swap to 3/4 makita impact but i still carry one of these in the cab. Nothing is more frustrating than fighting to loosen the nuts of the wheel on the side of the highway. Love this channel

[Nanan]

We have a Proto J6252 torque multiplier at work that says it goes up to 8, 000 ft-lbs, lets just say we have shattered 2" B7 grade studs with it when they just didn't want to come free. It has 1 1/2" input and output drive squares.

[jseen]

at 1:04 When talking about price and said "and our own Snap-On situated right in the middle" I perked up.

[danieljackheck]

We used one to test slip torque on drivetrain flanges for muscle cars. We often go well above 2000 lb-ft. We can then take the torque required to slip the joint and the tension created by bolts holding the flanges together to calculate to coefficient of friction of the flanges.

[TheEasylovin]

So i am a maintenance tech at an aluminum extrusion factory and we use a B-Rad 5, 000 for almost everything that asks for over 1, 000 lbs. love the channel btw!

I wish I knew where to find one… But I know what you need. Years ago I was working on a tractor with my dad, and we were unable to get the rear wheel off because our household air compressor wasn’t up to the task of keeping the impact going Long enough to break those big giant Lugnuts loose.

My dad worked at a factory and he knew the shop foreman. He was able to borrow this wrench from the machine shop, that was basically like a 6 foot long ratchet with a 1 inch drive socket, and in the box it also had a 4 to1 multiplier box, that you could put on it to amplify the torque. It was a beast. The funniest thing was even with all that one of the Lugnuts was so stuck. We put a 6 foot cheater bar on the handle of that giant ratchet, trying to get it off. So just imagine someone hopping up and down on a 12 foot lever with a 4:1 gearbox… I really thought we were going to snap the stud off, but it finally broke loose with some help from the torch heating it.

I've got a 3/4" drive SnapOn X4 (1000 ftIbs) that I purchased second hand for £150 of my old foreman when he retired.

Definitely one of my favourite tools and it's amazing how much you use them once you've got one. Main thing is being able to torque to 500ftib plus without having to lug a 6ft long torque wrench around.

[Bob_Adkins]

I love the ratcheting one, you can torque up the bolt real high and walk away. It will let you know when it breaks loose. You can also apply a little heat or vibration while it's torqued.
