Barn find 1931 SW 160-B

[Tom Wesenberg]

Just slam the oil pan upside down onto the grass to knock out the dipper tray. After cleaning the tray and pan, hold each up to the light to check for pin holes. I bought a nice looking oil pan at a swap meet that still had 2 quarts of oil in it. I have no idea why someone would leave oil in the pan, but after I cleaned it, the oil pan had 4 pin holes through the bottom.

Also, while the pan is off is a good time to check clearances. At the very least grab each connecting rod and see if you can feel any radial play. They will have some side play. Also look for any babbit squishing out the sides of the bearing caps. The center main is usually the first to go.
