Product Questions & Answers

part number 25503-313, is that the actual OEM part straight from Danfoss, or is this some kind of aftermarket knockoff with that number stamped on it?

Question by: Rusty B on Nov 16, 2025, 1:49 PM

Sourced directly from Danfoss Power Solutions, so yes, this is genuine OEM. The part number 25503-313 is the manufacturer's own number, not a third-party replacement wearing that stamp. You're getting the actual IDL gear assembly as it came from the factory, which matters when engagement tolerances and load transfer inside the pump assembly need to stay within spec.

Will this gear assembly work with any Danfoss piston pump?

Question by: Ronnie M on Jan 5, 2026, 8:13 PM

It's available in all configurations and sizes, so it should be compatible with a range of Danfoss piston pump setups requiring an IDL gear assembly for the auxiliary drive function.
