I saw a post of someone asking about torquing the steering head ring nut.

I made a tool using a friends waterjet cutter (cuts steel with water!) To get the tool right I need the dimensions of the original Yamaha tool. What I need is the distance from the torque wrench socket to the center of the ring nut. If someone has this I can make them for anyone who wants them for about $15 (my Yammy dealer wants $42) and he doesn't even have one himself for me to measure!

You can look at the one I made at Go to the photographs section.

I have also made multi purpose wrenches (axle, spoke, etc.) that are compact to fit in my fender bag. All tools are made from T1 tool steel.

If anyone is interested or has the measurements please let me know

Hey, that's a really cool service! Unfortunately I don't have the measurements but if you get them I'll certainly buy a tool from you for $15! :)

I would like one as well! It sounds better than the one I made in 1982. I globbed two welds on the ends of some adjustable pliers. I had a chance a while back to see the water jet at Utah Sports Cycles skid plate facility. It was amazing. The cut sides look like they have been sanded.

An M-16/AR-15 barrel take-down wrench, the short type, works perfectly, just grind off one of the splines and viola. It even has a 1/2" square hole for in the center of it for a 1/2" drive torque wrench. They only cost $9.95 from Sherluk Marketing.

:D How the HELL do you know that an AR15 takedown wrench will do this??? Do you use your 426 as transportation when spotlighting deer? Just wondering.

The 'hopper' :)

I looked at the M-16 take-down wrench. Looks like it will work, but I wouldn't use it expecting to get an accurate torque. The distance from the center of the nut to the center of the torque wrench head is critical. Too long and you will over torque, too short and you will under torque.

As soon as I can locate an original Yammy tool or get the measurments I will contact anyone who has indicated they want one to make sure you still want it.

If someone has a stock Yammy tool, I can draw it up in AutoCad if that is of any help to anyone. I can mail you a paper print if you don't have AC on your computer. And, yes, I will mail the tool back to whomever sends it to me! :)

Just shoot me an Email if this sounds like a plan. Otherwise, put me down for a wrench, too.

When using a tool like that, you must have the wrench and the tool at a 90 degree angle to each other. I believe the Yamaha or a torque wrench manual tells you that. It is not much different than the Yamaha tool, but they must be perpendicular for torque accuracy.

I think the length still makes a difference even at 90 degrees. Try holding a pencil vertically by the eraser and pulling on it with the other hand. Easy if you pull at the point, but hard pulling near the eraser. I might be messed up here though?? I am going to the shop and try a make-shift test. Will let you know if I figure out anything.

I already have it drawn on Cad. (and converted to CNC). Just need the length to finalize it. Thanks though!

That procedure came from my Snap-on torque wrench manual.

I was looking at the OEM tool in the manual and it looks like nothing more than a short spanner wrench with a square hole in the handle. There is still the distance between the square hole and the actual wrench on that tool, too.

I'll take one when you get it worked out. Thanks.

I'll have one made from tool steel or Stainless...

The trick with torquing correctly is to compensate for the extra length - simple math and you can set your torque wrench to an appropriate setting so if the centre of the hole is 2 inches, then you have a torque wrench of 18 inches, then you have to work the ft/lbs out on a 20inch length...
