Question by: Joyce A on May 8, 2025, 6:58 AM
Reckon this'll fit on my old Case backhoe? It's been giving me fits lately.

This Danfoss/Eaton X20 pump, with the 3.80 CID (63CC) displacement, is used on loader backhoes, so it is likely a compatible replacement.
Question by: Marvin W on Nov 23, 2025, 8:53 PM
what all can this pump handle? got a loader backhoe and a mini excavator on the same job site and tryin to figure out if one pump covers both applications
Answer by: Customer Support on Nov 25, 2025, 6:42 AM
Both of those fall squarely within what this pump was built for. The 420 Series is listed for loader backhoes and mini excavators, along with a pretty wide range of other mobile equipment like crawler dozers, articulate haulers, and rough terrain forklifts. At 3.80 CID (63cc) displacement with high pressure and flow capacity, it handles the kind of varied, demanding work that comes with running multiple machine types on a job site.
