Deke,



I went out and measured my bolts and looked at the NSI manual.  The bolts on

mine are AN5-7a's and the torque value is 100 inch-pounds.

Hi, Mike.   Thanks for the input.  I just checked my bolts again and I was 

wrong.  They're actually AN5-11A, not -10A.  The bolts I have are the ones 

that came with the FWF package.  My manual doesn't give a bolt size that I 

can find, but it does clearly say to torque to 150 in lbs.  Again, I checked 

the chart  I have and it says 180-220, but there are so many variables to 

torque values that when using charts it's almost an estimate.  Then I 

checked for torque values using Google and that's when my head really began 

to spin.  Too many variables, like crow foot, oiled bolt, dry bolt, zinc 

plate, no plating, tensile strength of bolt, strength of nut, etc.  It just 

goes on and on.  Fortunately  I have the NSI numbers or I'd end up not sure 

at all what to use.



Anyway, I'll be using 150 in lbs, not only because it's what my manual says 

to use, but it also sounds reasonable to me.



Actually, my question was what to use when there is no manufacturer number 

and the chart says 180-220 in lbs.  Never really got an answer to that, but 

I'll let it go.



Thanks again,

Deke
