Product Questions & Answers

Got a loader backhoe sitting idle cause the pump gave out, this a straight swap for something in that class of equipment?

Question by: Lynn T on Feb 20, 2026, 7:41 AM

Loader backhoes are one of the core applications this pump was built for, so you're in the right ballpark. It's an open circuit piston pump running at 3.80 CID (62CC) displacement in the 420 Series, and the part number is 421AK00326B. As long as your machine was running a compatible Danfoss/Eaton X20 open circuit setup, this is the pump you'd be looking at for that replacement.

Will this work on my loader backhoe? Seems like the size is right, but want to make sure.

Question by: Harvey A on Mar 7, 2026, 6:01 PM

It is commonly found on loader backhoes, as well as agriculture tractors and mining machinery, so it should be a suitable option if your current pump matches these specifications.
