When I removed the flywheel on my D-6, that is about the amount of play in 
the crankshaft.  It still runs 6 years later.!!!!  Remember, they only run 
around 1200 RPM, so there is not so much other forces at play.....   I would remove 
the bearings and try to install oversize bearings.   Use a plastigage or get 
one of those cheap digital calipers.   If you are within 15 thousandths, it 
would run great.  Use heavy oil and it will probably purr...
 Those old Cats are amazing at the abuse they will take.....
