My next BIG Project!!

[Lane Ranger 11,507]

 

I am going to have some new  Schnacke Nuts  made for Kohler K 90 and 91 motors!  
 

I acquired a Schnacke with my latest RJ purchase and the 1 1/2 inch HEX Nut was already rounded which explained why the Schnacke was off the motor and the rope pull was being used!

McMaster Carr sells 7/8 HEX rod in different lengths.   I bought 12 inches which should make 7 good ones 1 1/2 long.  I am also going to have the 7/16 x 20 threads placed on each end so the Kohler HEX Nut can be reversed and used on the other end after wear

Great idea.

I suppose one could weld up the worn portions, then grind/file the welds back to hex.  That's assuming that the nut does not meed to be hardened.

Joe Papke, the Schnacke Guru   says I will need to harden these  hex nuts so that will also be done on this project.

 

  I know the right blacksmiths with the right furnaces!

You can only case harden cold rolled steel, but that isn't the best option for your part.  You should have purchased an alloy steel and hardened it.  One option

McMaster Carr stocks higher carbon steel hex that could be hardened.  Won't be tool steel hard, but it can probably get into the 40's on the Rockwell C scale.
