Same here.

55 ft/lbs. is snug and then a little extra (about a eighth of a turn).

So about 60 ft lbs? 65?


55 never seemed tight enough.

I meant to say is that to get 55 ft/lbs., I make it snug and then tighten it about a 1/8 turn.
I know it is over 55 but not by much. 65 or 75 ft/lbs. isn't going to hurt anything. When 55 was determined by Merc, we didn't want people to overtighten and strip threads. There is also the lock washer to prevent loosening.

I torque to 55 and then give it just a little bit more of a turn. The OP asked for the torque spec.. that's what I gave him...
