Replacing the gaskets on my rear rocker box. Torque wrench question.
So I'm replacing the top and bottom rocker box gaskets on the rear cylinder of my Sporty. I already have the top box off. Of course I staggered the bolt removal and did it a 1/4 turn each.
I'm using a rocker box thin Allen wrench to help with removal so it'll fit. The issue I'm going to have is when I tighten the left rear bolt down. The slim wrench has a square slot to fit the (in/lb) torque wrench on. It's 3" from the bolt. I will insert the torque wrench at a 90* angle to the slim wrench. My question is; Will I have to adjust the torque value to compensate for the head of the torque wrench being 3" down from the rocker bolt?
Yes, initially I will do the proper procedure and turn the bolts a 1/4 turn in a staggered pattern. It's just when I want to set the final torque values I, obviously, want all four corners to be exactly the same.
So will using the torque wrench effect the torque values? If so, how do I compensate?
Thanks.

If you put your extension on the drive end of the torque wrench at a 90 degree angle...it does not affect accuracy of the torque wrench, it's reading, and the click happening at the right point of being satisfied.
If you put the extension on at any other position other than 90 degrees (right angle)....you will have to refer to a chart (plenty of them out there on the 'net, often torque wrenches come with ones too).
If you don't believe that...just torque down all 4 using the extension..that way all 4 are still equal.

What is this "slim wrench" you speak of? Pics? Where did you get it? Thanks

I actually ended up using a ball ended allen socket. It worked better. But, you can't have too many tools.

Had the same problem when I rebuilt the cam chest on mine. I did the calibrated wrist thing with a box end wrench.......been doing it for years on all kinds of hard to reach bolts and never had a problem. Tighten them all down to close, torque the ones you can reach, put a wrench on one that's torqued, and feel how tight it is (calibrate your wrist). Then "torque" the hard to reach one/ones to the right "feel". Really not that big a deal on covers.
