I bought this torque multiplier a few years ago and haven't gotten around to fabricating a handle for it. I had to figure a way to hold it in place to prevent rotation when applying force to the torque wrench.



Worked like a champ. Oh, and in case anyone needs to know, the torque values for the axle nut are:
  • 235.2 - 274.4Nm
  • 23.99 - 27.98 kgf-m
  • 173.5 - 202.3 ft-lbs
The axle nut is 32mm. A 1¼" socket will work, which is what I used.

Another pro tip, buy some of the ARP ultra-torque thread lubricant/torque spec magic sauce, it's designed for more accurate high-torque application. I was able to get the extra 1/4 turn or whatever with just a 26" harbor freight breaker bar.

To the OP... excellent info. Are Torque Mulipliers expensive? Re the ARP magic sauce.... while I have no doubts that ARP is credible re torquing-up rodbolts, etc. the whole matter of cleanliness, lubed or not, what kind of lubricant, etc. is a complicated subject.... and big differences in stretch can occur depending on these specifics. What does Mazda themselves suggest...'cuz it's Mazda who has spec'd the torque value...?

I found it on e-Bay and can't remember what I paid for it. Considering how important proper torque is on an axle nut, that's one tool where I won't quibble on price.

A lot of guys have different theories about using oil, anti Seize, or other lubricants on threads. From what I've read, these affect the final torque value by 12-15%.

Most torque values are dry unless otherwise specified.
And yes, oiling the threads can increase the applied torque well past the specified amount.
