Leybold Coupling Insert, Part# 20009095 – vacstellar

Description

This part matches the original Leybold 20009095 exactly. You’ll see it listed as one piece in most major repair kits for these Trivac pumps.

Changing it is quick once the coupling cover is off – just slide out the old one and push the new spider into place. It’s a small part that makes a big difference in smoothness and long-term reliability. 

it carries the power from the motor to the pump, and it flexes a little to soak up shocks and small misalignments.

When this spider wears out, it cracks, loses teeth, or gets soft. Then you hear knocking sounds, feel extra vibration, or the pump runs rough.
