Front Cradle Torque Specs
« on: February 11, 2011, 10:38:35 pm »
I am putting the front cradle back on after getting back from powdercoat.  What are the torque specs of the bolts that fasten it to the frame?  All of my pics are too large at the moment.  I will figure a way to do a resize or an album fr all to see. 
Many thanks to all,
Fidd

Make sure the bolts are grade 8 too.

Give me a long enough lever and a place to stand, and I shall move the earth or break this bolt...Whatever, just hold my beer!

Never done it, but I were in the same situation, I would just use these accepted max torque values as a guideline.

Thanks everyone.  I was able to find what I needed.  Cradle to side rail is 65 ft/lbs and to bottom rail is 90 ft/lbs.  Just in case anyone else wanted to know.
