DCP00353.JPG (294412 bytes)Here is our engine for the sawmill.  It is a 1948 D318 Industrial rated at 78.5 Hp at 1720 RPM.  Basically it is the same engine as in our Caterpillars but with two more cylinders.  Here it is where we picked it up in Ohio, a 1,700 mile round trip from home.  It is stuck from sitting several years so we have to pull the head and free it up.

So then we removed the pistons and found the crankshaft needing to be ground.  A complete overhaul is in the works.
