Torque Question

Proto Tools makes a boxed end "crows foot" that can be used on your torque wrench. Snapon and other quality tool companies may also offer them.
Do a search in Google to find a photo of them.
May tool makers make open ended crows foot wrenches, but very few make then in the boxed end style.

Install it 90 degrees to the arm of your torque wrench so you dont have to calculate the increase in the lever arm length.

I believe you do need to compensate even if its at 90 degrees

At 90 deg you don't have to compensate for additional length. If on the other hand you use it as per the above drawing then the compensation is required.

If the adapter is 90 degrees to the lever arm of the wrench it does not increase the lever arm length, so the torque reading is the same as if there was a socket on the wrench.

The diagram you show is for the adapter inline with the wrench increasing the lever arm

Ohhh I see. I didn't think it through. But I didn't know that. Good info! I've always used the conversion and 180°

I've always done two levels. Usually half the finish torque and then the final. In doing the cross pattern I get to that one last and use a box end wrench to do it. I bump the 3rd nut that I just torqued with the box end to get a feel for the amount of strength, and then hit the nut in question. I repeat for final torque. I've never had any issues although that's not the right way to do it

I was going to tell the OP the same but didn't for fear of getting thrown under the bus by some know it all internet mechanic out there. You wont have a minutes trouble doing this as long as you use common sense (a real unicorn these days) and tighten the nut as close as reasonibly possible to the torque of the others.

If you must use your torque wrench http://www.motionpro.com/product/08-0134 Your local dealer should be able to order this tool for you out of a Parts Unlimited or Tucker Rocky catolog. Like the posts above, try to get the tool 90° to the torque wrench. If you cant, try to get it as close as you can. Common sense works well here also. It's a dirt bike, not the Space Shuttle.
