JR 8411 Gear Conversion

[Jerry Budd]

Bob,

You can nearly eliminate the last little bit of slop from the 
8411/8417/9411's by changing the final output gear to nylon (beware, 
it's very difficult to remove the recessed lower bearing on the 
9411).  It's also a bit lighter when you're done.  I've found no 
drawback to the conversion, in fact I wish the SA's came stock this 
way.

Thx, Jerry
