 I dont know if you have room ? but I have drilled the edge of the nut an also the edge of the bolt head. I then used stainless wire to keep all from turning( I used .o32 wire from my wire welder) just be careful while twisting the ends together,to tight and they will break. Hope this helps!

Bob: A few words of caution on that type of fan drive if you have to work on the box.

Make sure that the fan is balanced and a light weight plastic fan is preferable to a steel fan.

Any vibration takes out the front bearing in the box which puts the fan into the rad.

Make sure that the gears are properly set up. It is a tedious job shimming the two sets of bearings (even worse than setting a crown and pinion). If you take it apart make sure to mark the location of the gears. On a 1 to 1 gear set they always mesh on the same teeth and wear in that way. If you change the relative position you will have high spots and low spots which make it impossiible to shim properly.

 I speak from experience because I didn't mark the gears and it took me two days moving  a gear one tooth at a time to find the original location. After each move you have to reshim both sets of bearings and tightern everything down to test it. If you put the gears back in the original position it only takes about four hours to get the shims right. You want this gear box to turn freely with almost zero backlash.

Thanks Stan - I had mine rebuilt by a local machine shop about a year ago.  It seems good but I will check the freeplay in it tomorrow before I put it back in. And yes I do have a plastic fan.
