[quote="GordnadoCRD"]the torque sleeve is a smaller diameter than the body it would have to go past, so a socket won't work.
What I was planning to do was take a piece of 1/4" x 2" x 16" steel bar stock, Heating it and bending it around a piece of 4" pipe, so the ends are parallel, and trimming any parallel access off. then one end would have a 30mm socket cut into it, and the other would be drilled at the same center axis, and a broken 1/2" to 3/8 stepdown drive welded there, so wrench torque would equal actual torque. It wouldn't have to be anything super hard since the most torque it would need to hold is 59 ft lbs.
Now, with this tool, all I have to do is measure the distance from the center of the square drive to the center of the valve axis. and do a bit of math.
(for example) Given, that a torque value in ft/lbs is lbs of force applied at 12" from the rotating axis, applied 90 degrees to movement, no matter the size of the torque wrench.
IF the distance from the center of the tool drive is (fmy example)2" you would add the 2" to the 12" that the wrench is designed for, and divide (12/14) as correction factor. And the torque value needed is 44 ft lbs Then you would multiply 44 x (12 / 14) = 37.7 ft lbs for the wrench setting. I would just round up to 38.
As much as I hated algebraic story problems 4 decades ago, they have been really freakin handy in life.[/ quote]
I think that tool is slotted such to be wider in the center and 30mm at the end, and be specific to this application, but either way, a $6 crows foot (plus shipping) and your fine math is much better! I'd like to see if the local Bosch place can get it just for kicks. Heck, what does the manual call for? I might have the tool in my factory set lol
