Is this thing gonna work on my log splitter? Just need to know if it's compatible before I order it.

This Eaton-S2 39 variable pump is a Char-Lynn branded hydraulic pump, so as long as your log splitter is compatible with that brand and part number (3922-091), you should be good to go.

what brand actually makes this pump? i see Danfoss and Eaton both listed and just want to make sure i'm ordering the right thing

Question by: Tammy G on Apr 15, 2025, 9:00 PM

Char-Lynn is the brand on this unit. Danfoss and Eaton both have ties to the Char-Lynn line through acquisition and rebranding over the years, so seeing multiple names on the same part is pretty common with this product family. The part number to match is 3922-091 regardless of which name shows up on your paperwork.
