Smoother running of the Piteba oil expeller

The Piteba oil expeller runs smoother when a leather washer is mounted on either side of the metal washer. This prevents wear on the washer.

Leather rings to prevent wear of the Piteba washer

Below is a description:
  • Take a smooth piece of leather of approx. 1 mm thickness.
  • Cut out two rings with a maximum diameter of 28 mm and a hole of 14 mm.
  • You can also make two hole punches from pipes of suitable diameter to which a sharp edge is ground (see bottom picture).
  • Slide the washers onto the expeller screw with the metal washer in between.
