This coupler set fits within a gerotor setup, serving as a spare part used within the gerotor assembly itself. It's intended for use in Danfoss and Eaton gerotor assemblies, aimed at repairing or rebuilding part of the system rather than replacing the whole motor.

Answer by: Customer Support on Nov 14, 2025, 4:57 PM

What you're getting here is the full gerotor coupler set, a real Danfoss/Eaton replacement assembly, not just individual pieces or connectors.

Question by: Shawn C on Jul 30, 2025, 8:59 PM

can this be used to rebuild a gerotor motor that's leaking internally

Answer by: Customer Support on Aug 2, 2025, 4:22 PM

Assemblies like this gerotor one are usually used to swap out worn internal rotating components causing leaks or performance issues. If your motor is having internal leaks or reduced output, installing a new gerotor set can restore its functionality without needing to replace the entire motor.
