pilot motor specs

Hi all
I am rebuilding a pilot motor of a diesel 40 and just wondering if any one out there has the specs for this engine.
tensions,clearenses,hp,ect its vertical with 3-5/8" bore and would a pilot motor of a d74t be the same size ?

Info I have says the 35 & 40 used the 3-3/8" bore pony (same parts as Cat 10)
The 3T's/4T's used the 3-5/8" bore engines.
Apparently the complete motors will interchange.
