Rockwell T221 lives
 

Kept my 221 alive. Shortened np205 coupler, modified (ground inside ends of splines to fit) and used national seal number 40071s to make up the shaft size difference. $54 for a new coupler and $17 for the seals. Much better then trying to find a good used T221 coupler. Hope this helps somebody else.

It's been 10 years since I did this, last week I pulled the case to do seals and the input bearings. Still dry as could be around the 205 coupler.

I have a core T221/SM465 I'm thinking of running in a future project.
