Folks...

 

I'm trying to find a proper key for 6 and 8 speed input shafts. 

The shafts are 5/8" diameter. 

I have a key from a mid 70s 8 speed here. Appears to be stepped??

 

Looks like it should be 5/32 but there's several.  

How can I narrow it down?

I'm not sure Eric. I was thinking 3/16" on the 5/8" shaft. I'm not sure what you mean by stepped.

937221 key is a Woodruff 6 and the size is 5/32" x 5/8".

The key is listed as a Hi Pro type in the parts lists and that is what you are describing. The extended ends prevent the key from trying to rotate when installing.

I do not know if the #6 is a standard key or one with the extended ends making it a Hi Pro style.

Here's a link to what we have.

I looked up the key for my 2005 8 speed. P/N 937108 which is 1/4" x 1 3/8" which likely is correct. I'm comfortable in saying that there isn't any of those stepped keys on the tractor.

Which makes me wonder...

Is there a specific point or need to be extension other than ease of installation?

I have no clue. I've never seen one before.
