Who knows what they were thinking. I'd just weld up those holes and use that tray.

Look again. The holes are not affecting the oil levels in the dipper sump. Whatever amount of oil that was in the sump when the engine stopped rotating is the level that would have been there during start-up. Therefore the rods would not have been dry when the engine was started.

Brent, my comment was referring to the example I had just given about holes in the bottom of the dipper tray - not the ones in the picture. With holes in the bottom, the oil drained out very quickly so the rods ran dry till oil filled everything up again.
