Torque setting for blade bolts?

I'll check my manual but was wondering If anyone uses a torque wrench to set the blade bolts.
Or do you just tighten the crap out of them, with anti-seize of course?

When double blades are used do you use a slightly longer bolt?

Does Meg-Mo recommend a torque setting?

Hey Bug, In the discusions from the past, I believe it was stated that the torque on the blades was 75 lbs. The biggest complaint of not having them torqued enough, was that it would make the blades ALOT harder to remove the bolt. (might be wrong about the torque setting......I'll look in the archives. As long as their torqued atleast that much, no prob. getting them broke lose later)

Most all used a 1/4" longer bolt, made of a high grade steel.
Believe Hoss always recommended putting a little bit of oil on the bolts, and spinning the blades (with no burrs, they go right up, together....same to un-do them, break them loose, and spin the blades off........by hand of'course.......might not have been you Hoss, and if not sorry (been many, many years) (could have been Eric)

I know nothing about Meg-Mo.

Always good to search.....so much to learn along the way. Hope I told you the right torque specs........I'll search in a min. myself.
(too loose, and the bolts will tighten themselves way too much......making it about impossible to break loose later/atleast alot harder) and go with atleast a 1/4" longer bolt to make up the diff. in the extra blade. (never run doubles myself, but I hear they are great) Later Bugspit! (kool a$$ name BTW)

Here is one old thread Bug, that will atleast tell more about the "self-tightening" effect caused by blade bolts not tightened enough. (have seen diff. torque specs. for blades, form 55-120 so not sure what to tell you, but from what I hear, tighter is better (to an extent)

Well, what you do is tighten your nut/bolt with the impact and then use a torque wrench, starting at a low setting and keep raising it until the nut or bolt moves. that will give you an idea of how much torque you're applying with the air impact.

Try this several times and depending on consistent conditions of air psi this could be a means of calibrating your air tools.

Thanks Metro for your input.

WELL, EXCUSE ME.
Had no idea you were a mechanic, thought I'd offer some friendly advice.
