Product Questions & Answers

Will this motor swap right in place of my old Char-Lynn 420 Code B? Been havin' a heck of a time findin' the right replacement.

Question by: Dean J on Apr 11, 2025, 6:44 PM

This Danfoss/Eaton motor is a direct replacement for existing Char-Lynn 420 Code B hydraulic motors, so it should fit right in. Just double-check the part number (421AK01379B) to be absolutely sure.

Been trying to pin down the right replacement for a Char-Lynn motor on one of our older pieces of equipment. The part number I got is 421AK01379B. That line up with this unit?

Question by: Roy B on Sep 5, 2025, 7:04 PM

Yeah, 421AK01379B is exactly what this motor carries as both the SKU and the manufacturer part number. The full product designation is the Danfoss / Eaton 2.50 CID 42cc 420 Code B, sold under the Char-Lynn brand. That brand name transferred over when Danfoss acquired the hydraulic motor division from Eaton, so you'll still see Char-Lynn on the unit itself. As long as your equipment calls for that specific part number, you're looking at the right motor.
