cylinder base nuts

[overbore]

I have them torked after borrowing a adapter that
motion pro makes to get to them,but wonder how
most people or factory torques them from the start.

Use a crow's foot on a torque wrench. Just remember to make the proper torque compensation for the length added by the crow's foot.

i have a torque extension from snap-on, its 2" long, how do you know how much to compensate for the extra lenth.

If you put the crows foot on 90degrees to the centerline of the torque wrench you do not need to compensate for the extra length. If you have to do it inline here is the geeky engineer method.

C=LW/LW+LA
Where:
C=correction factor
LW=length of original wrench (from center of square drive to middle of your hand when it is on the wrench)
LA=length of adapter (from center of square drive to center of bolt.

Example:
Using a 12" long torque wrench and 2" long crows foot
Torque you want is 100 in*lbs
12/12+2=.857
.857*100=85.7 in*lbs ---this is what you set your wrench to
So, you can see that if you can get away with the crows foot being 90degrees to the torque wrench it is much easier.

Hope this helps

Thanks for all the responses.I will try and remember that formula for future
use.I think it was the same as the one that I used from a friend that was
from motion pro.I just couldnt believe that when they build these things at
the factorys that they do it this way.

I'm sure at the factory they have crows foot wrenches that are sized such that they can torque the nuts with the crows foot positioned 90 degrees to the axis of the torque wrench. That way there is no correction needed
