Lube It Up! Two mechanical lubricators with 2 outlets each, were used. 0ne lubricates the cylinders. The other lubes the axle pump eccentrics (pictured below in Yellow) and crosshead bars.
As you can see in the picture, a cross member was added to stiffen up the frame. When this thing runs on air, there's some heavy torque going on. MODIFICATIONS: I originally had oil lines going to the axle pump housing (in red above) but quickly found out that oil was getting into the water supply. I am now doing what others have done and rely on the water to lubricate the axle pump pistons.
Pilot Truck Ball/roller/needle bearings were used on everything except the pilot truck. The Little Engines design used plane bearings. Oil cellars were made and stuffed with velour cloth. To make it easy to lubricate the front journals, a manifold was bolted to the front truck with oil lines going to each journal. An oil cup was connected (in red below) to the manifold and installed near the mechanical lubricator for easy access.
If you look close enough, you can see the tubing and manifold.
