Product Questions & Answers

Got a crawler dozer sitting idle cause the pump went out on it. This a 420 series X20 unit, 3.80 CID displacement, open circuit piston style. Would the 421AK01651B be the right fit to get it back running?

Question by: Rick B on Mar 28, 2026, 9:10 PM

For a crawler dozer running an open circuit piston pump with that displacement, yes, the 421AK01651B lines up. The 420 Series X20 platform covers crawler dozers as a listed application, and the 3.80 CID (62cc) displacement matches what you're describing. Part number on this one is 421AK01651B from Danfoss/Eaton, so if that matches what came off the machine, you're looking at the right unit.

Can this pump handle the kinda work a feller sees on a crawler dozer day in and day out?

Question by: Dustin B on Aug 23, 2025, 12:22 PM

This pump is well-matched to the heavy duty cycles common on crawler dozers. Its high pressure and flow capacity makes it suitable for consistent hydraulic output under shifting demand.
