got a 420 series open circuit piston pump I'm trying to replace on my loader backhoe -- does this one fit the bill at 3.80 CID?

Question by: Wade W on Oct 21, 2025, 2:07 PM

For loader backhoe applications, that displacement and series combination lines up well. The 421AK01932B is a 3.80 CID (62cc) open circuit piston pump built on the 420 Series platform, and loader backhoes are explicitly listed among its intended applications. As long as your machine is set up for an open circuit piston pump at that displacement, this is a direct match for that use case.
