I'm having issues breaking main cap bolts during assembly. I am using 15ft lbs of torque. I have purchased new bolts with same issue! Help would be greatly appreciated.

 

Buy a new torque wrench.

 

I did same result!

 

Your not confusing 15 with 150 are you, Because 15 ft # won't break a main bolt,
somethings not right here, are you having to put some strength on it to achieve the
15#? 15# is barely anything at all.

 

Hi Bss, could you state the tightening method AND the bolt/stud fitted ?

Agreed 15ftlbs is barely snug, you absolutely are doing something wrong.

 

It is VERY hard to feel the click of a click type torque wrench at low torque levels and you'll usually go way past it waiting for the click. At higher torque the click is a very adamant click, at low levels it doesn't really click it just kinda pops over. You need to get used to the feel of it first.

When I have to use very low torque like that I clamp the square of the torque wrench in a vise and lightly pull on it until I get the feel down and then I go over and torque the bolt.

When using that low of torque try stabilizing the wrench and then pulling it with one finger, that might help also.

 

try using a 3/8" drive torque wrench instead of a big boy

 

You are referring to the 10mm side bolts, not the actual main cap fasteners, correct?

 

That's what I was assuming too, surely he is referring to the side bolts.
