Some of the shaft...
I figure some one would ask about the final on the shaft...
After measuring the two journals I shimmed one "V" block .030 and claped the whole thing to the table - tacked, rotate 180, tacked, rotate 90, tack, ect...
Then I started runing small 3/8" long root beads alternating sides... Fast foward about 8 more passes and the finish cover weld can be seen...
The TIR was around .004" at the second journal and ~.002 - .003" concentricity at the sleeve - I think this was mainly from having the clean the press plug hole that was non-cocentric as supplied from the factory with and endmill in the lathe...
All in all I was pretty happy - we'll see if it lasts...

I will try and get some pics of the rebuilt NP202 - I did not shoot internal pics as a big gear case is not very exciting and I was busy chasing falling parts with no manual - there were 150+ loose needle bearings in various bores...
