When working with tensioners like this, our goal is to end up with a preassure close to, or slightly higer than B. Ax3+Bx3 = close to B. Your equialized preassure between A and B. So, if you move one of the tensioners back to a random A-bolt and test it, if you have done this correctly, you'll see it releases close to B. if not, if the preassure is alot higher than B or alot lower than B, you need to start all over again.

When tensioning in 50% configuration, Pressure A is Pressure B x CLF. Cross Load Factor (CLF) can range from 1.15 to 1.25 Pressure B is calculated considering the residual load x LTF (Load Transfer Factor). the LTF depends on the grip length or the effective length of the joint and the bolt nominal diameter LTF=1.01+(diameter/grip length).

What is the cost of those lugs snapping loose from over torqueing with an impact? Runaway tires can lead to devastating results, that's why a lot of companies are switching to precise tools with data capture.

@christianhartwig90 If the shop is paying, I'd use it. Unfortunately, once tools become the standard, employers just expect technicians to "have own tools."

When working with tensioners, its always 1 out of 2 procedures. What we call a 50% tension procedure or 100%. So tools on half of the number of bolts, or tools on all. No more, no less.

and if you use 100% tool precedure, you do not need the A preassure anymore. Just go for B x 3.

For this application, the goal is not power, but precision. What we've seen is that impact wrenches can often over torque bolts which can cause them to fail over time. With precision tools like the LION GUN, you can count on the fact that every bolt will be tightened properly. You can even keep track with GPS location on the HYTORC CONNECT App.

That's pretty efficient for government work

It will work!

The J-Washer has several advantages. Due to the construction of the washer, there is no need for a reaction arm which provides multiple benefits. The first is that load accuracy is improved due to concentric loading. The second is a safety improvement by eliminating the possibility of a pinch-point injury. Additionally, less torque is required to reach your bolt load target due to the placement and size of the topside locking knurls. In terms of cost, as the J-Washer is a 1-piece washer, the cost advantage of our washer grows as the size of the application increases. We have bolting specialists around the world who are ready and available to further discuss the advantages of our system. Please reach out to us at www.hytorc.com/contact or at 1-800-367-4986 and we can connect you with a local expert.

Also, you don't technically need to use the socket driver to tighten a bolt with the J-Washer. You could use a reaction arm like you would need to with a wedge-lock washer. I would recommend upgrading to the socket driver though to eliminate side load.

Thank you!
