What is that odd 12 pt. nut on the LN IMS bearing shaft?


Recommended Posts

I've discovered one more snag before I install the LN IMS bearing.  I'd neglected to source a tool for the 12 point nut supplied by LN.  What the heck is it?  I've held it up to my triple-square bits and it looks to be midway between my M12 bit and my M14 bit.  Charming.

 

The only work-around I've found is that a deep 6-point regular 12mm socket fits this nut "good enough".  By "good enough" I'm only supposed to torque this thing to 7.5 ft. lbs. (90 inch lbs.).  Is this what everyone does? 

 

When assembling the bearing into the bearing driver tool, LN says

 

Drop in 12 point nut and snug up to hold the bearing, bearing support/center stud, and bearing driver/installation tool as a single unit. INSTALL NUT FINGER TIGHT ONLY.

 

 

I'm mostly concerned about getting the nut out of the bearing driver tool when the time comes.

I found a comment from Jake Raby on another forum.

 

The fastener in question is referred to as a "jet nut" and is an aerospace quality, completely flat based nut thats far superior to anything from the factory.

No special sockets or adaptors are necessary, just a 12 pt 11mm or even a 7/16" box end wrench or socket will fit just fine.
