Dwain...need to know the size (diameter) of the bolt in order to get the proper torque specs....Many times after they are tightened, the constant back and forth of motor torque compresses where its clamped and loosens up....make sure you have a really big washer (along with the standard bolt washer) or backing plate to spread the load as best you can. Also, I would use blue threadlocker to keep the nut from backing off. Either get the bolt size back here or just type in on-line "bolt torque specifications" and a web site should have it listed.....most torque specs are matched to their respective size and are fairly constant in most applications.....most!
