Got a loader backhoe that needs a pump swap and somebody told me this series fits good for that kind of work. That right?
Answer by: Customer Support on Jan 17, 2026, 3:58 PM
Loader backhoes are actually one of the listed applications for this pump, so you're on solid ground there. It's a 3.00 CID (49cc) open circuit piston pump from the 420 Series, built for heavy-duty mobile equipment. The 5.75-inch width keeps it manageable in tighter mounting situations, which tends to matter on backhoe setups where space around the drivetrain gets cramped fast.
