NEIKO PRO 03715B 1/2" Drive Torque Wrench, 1100 Foot-Pound Heavy Duty Torque Multiplier Wrench, Cr-Mo and Chrome-Vanadium

Who needs an expensive cordless impact gun when you can buy this tool instead. It has a 3.5:1 gear ratio and doesn't require expensive batteries to operate. Once you figure in gear slop & friction loss the multiplier is really a 3:1 multiplier just so you know Basically, you put your 1/2" drive ratchet on one side and a 3/4" drive 6-point impact socket on the other end and proceed to break loose bolts torqued to over 400+ ft-lb with only a little over a 115ft-lb of torque on your 1/2" drive ratchet. This is what you call working smart via planetary gearing. With planetary gearing remember that the torque multiplier bar will move in the opposite direction you are turning your ratchet in. If you're rotating a tire that is using planetary gearing the wheel on the opposite side will rotate in the opposite direction. We used this tool to break bolts loose on our Allis Chalmers 7045 tractor that our Tekton 42" 3/4" drive break bar couldn't safely break loose even with a cheater/extension pipe on the end of it. This torque multiplier broke the bolts loose like it wasn't even breaking a sweat! It is a little scary when you first use it because the bolts make a loud pop when breaking them loose and you instinctively think that the bolt has snapped off in the hole creating an even bigger problem but luckily for us that wasn't the case! This is a must have tool in your shop especially if your working on large equipment! Just make sure you have a nice heavy walled pipe to go with it to brace the torque multiplier bar with.

Very helpfull when it comes to breaking wheel nuts loose on larger loaders like a Komatsu WA600. Nice case, I watched several videos about people complaining about the ratio, if you want to have a accurate tool, go buy the top $ tool, but for a field mechanic I think it's great.

Works great, but make sure you read the instructions and use it accordingly to rotation. You could easily go the wrong direction and over torque a bolt/nut instead of removing it and when tightening make sure you calculate the torque wrench accordingly.

Let me start with the list of two important problems using this type of tool: 1) The handle of this wrench needs to rest against an immobile surface, say, the ground. Because all of your leverage comes partly from this handle being captivated somehow against an immovable object 2) Which brings you to the second problem. If you manage to rest that handle on the ground, say, the object the wrench is attached to wants to lift up when you apply torque to loosen the fastener you are after Case in point. I purchased this to deal with a VW flywheel gland nut. The block is on my garage floor. The handle rests against the same floor. I apply a breaker bar. The block lifts off the floor. So, if the block were tied or bolted down to the floor, all might work as you wanted it to. In the end, I used a pneumatic air wrench to remove the nut in a few seconds. So the tool is an expensive paper weight for me unless I figure out a better way to fasten the target assembly to a bench or floor and that attachment can apply greater force than the tool (and not tip over my bench). All of the YouTubes of this tool show people taking off military vehicle lug nuts, or using the weight of a car to counteract the tool. So, I guess there are applications where the tool will work. I further suppose my application is not one of them. The tool itself is made well, and looks like a good quality product. I'm just not sure it's suitable for every big torque task. Some of these tasks I performed many times in the past by constructing a few long levers from flat steel, pipe extensions for my wrenches and loctite to prevent loosening.

First, for higher torque fasteners, over perhaps 200ft-lb, this is a great tool to have and reasonably affordable. As long as there is something for the reaction arm to rest on and room for the rather large tool head, the Neiko torque multiplier makes torque application much less of a strain particularly for one's back in awkward positions. And you really don't want to strain your back. Next, there are complaints about the tool having 3:1 laser etched ratio when the mechanical ratio is 3.3:1. So I did a quick empirical test because, yes, I don't want to substantially over torque fasteners: -- first verified the tool is 3.3:1 (1/2 wrench in one side, get about 3.3 turns for one turn of 3/4 side) -- next torque a couple of wheel lugs using tool, with 55ft-lb input (good quality CDI torque wrench) -- then removed torque multiplier, and adjust CDI torque wrench starting at 160ft-lb in 5ft-lb increments until I passed the lug nut torque that was applied with the torque multiplier. At 160- click, no movement of lugs. Lugs torqued higher than 160 At 165- click, no movement of lugs. Lugs torqued higher than 165 At 170- click, no movement of lugs. Lugs torqued higher than 170 At 175- lugs moved before click. So the torque of the lugs is between 170 and 175 This gives a torque ratio for this particular Neiko tool of about 3.1:1. The above is very empirical, no special calibrations were used. Using 3:1 is probably OK, perhaps adjust the input a tad low, or round down when calculating the torque wrench setting, or just figure that the fastener torque is not that critical and 3-5% won't matter due to other tolerances (torque wrench, dirt, fastener metallurgy, how much Wheaties was eaten for breakfast, ...). I like the tool, now those 300ft-lb strut bolts or 450ft-lb pinion nut pre-loads won't be quite so much effort.

Compact size gets into tight areas on our tree grinding wheel to torque 1" bolts properly. Definitely helped bring down our maintenance cost now that the bolts are tight enough. Though still a work out it's easier than a 6 foot cheater pipe on a breaker bar when you have to torque 60 1" bolts! Update: after a year & 4 months I broke it, torqued a lot 1” bolts to 800 fp. It broke the 4 planetary gears. Emailed nieko to get some replacement gears & they don’t sell them. Instead the warranted the whole tool for no cost to me! Excellent customer service!

If you go to Rennlist and search Center Locks Again you’ll find a write up that involves using this item. I also bought a 10-160 lb torque wrench on Amazon. Those two things and a block of wood are all you need to correctly tighten your Porsche Center Locks. I also had a Precision Instruments non-multiplier set on hand to compare. Both work, but the multiplier is less $$ and quite effective. Add a longer 1/2” drive breaker bar for loosening. I also used it with my weight distribution hitch from Husky as it requires 350 lb/ft of torque on the main bolts. The Renntorque setup is over-kill and over-priced.

bought this to use under semi truck and trailers doing suspension. Has worked great the few months I have had it. This has been the best when doing u-bolts close to the ground and under a trailer. i have a 6' torque wrench that does 600lbs but takes too much room to swing. This is a lot easier with my 24" 1/2" drive torque wrench in it.

Durable

No manual, spair O ring is for the 3/4 input to 1’’ output and the red box is big, hard to rotate. I opened the tool and apply grease to the gears inside…

I bought this torque multiplier based on good online reviews, and while I haven't used it yet, it looks and feels every bit as good as I expected. Next time I need to remove/replace tractor wheel nuts for example, I know it's there in the toolkit. I was always wary of using long breaker bars!

Had to get 600 ft lbs out of my 200 ft lbs torque wrench worked really well.

Product does everything that it is designed to do
