Rack setting bible has the 9S5001-up as Industrial, Marine and Gen set Engines
Specs vary according to full load engine rpm.One example is 54 hp continuous at 1800 rpm.
Close as I can get is 1953-1958 for late s/n engines.
Unit was replaced by 48Bxxxx in 1959
Thanks OM .
This was out of most likely a 15B Bucyrus Erie.
Were going to do a transplant into our D47U I posted back a couple months ago the we dragged in. Engine took in a good bit of water sitting uncovered out in the woods. I figure it'll be much easier just swapping out parts from the original onto the power unit instead of finding a better head and put in liners. A couple jugs were really pitted bad beyond just running the ball hone in to clean up.
That will be a balancer engine with later heads that can accomodate glow plug chambers and direct electric start. It will not have the front and rear scavenge plumbing for the oil pump.
