Re: Handitwin flywheel nut torque

[oltimer]

I am just finishing mine off with new rings etc. Generally a 3/8" size screw (16-24 thds.) would be 18-20 ft lbs. The fly Wheel nut on 3hp Evinrude/Johnson take 30-40 ft lbs of Torque. On our Handitwin models having 7/16" size in a 20 threads per inch, I would feel very comfortable putting it at 25-30 ft lbs, but leaning more to the 30 lb side. Now you also have to consider if the Fly Wheel has been taken off the wrong way before and became egg shaped, than I would apply more or get another fly wheel. Good Luck with your unit.
