Danfoss / Eaton-3.80 CID(62CC)420 Code B

Description & Features

Designed for demanding mobile hydraulic applications, the Danfoss / Eaton-3.80 CID(62CC)420 Code B is an open circuit piston pump built around the 420 Series X20 platform. With a displacement of 3.80 CID (62cc), it delivers high pressure and flow capacity suited to heavy-duty duty cycles across a wide range of mobile equipment.

This pump is well matched to loader backhoes, agriculture tractors, crawler dozers, mini excavators, articulated haulers, concrete and asphalt pavers, and container handling equipment, among other mobile machinery. It also sees use in railroad equipment, mining machinery, tunnel boring equipment, utility boom trucks, and rough terrain forklifts. Advanced control options support efficiency across variable load conditions, and the pump's response and recovery characteristics make it a practical fit for equipment that requires consistent hydraulic output under shifting demand.

Question by: Rick B on Mar 28, 2026, 9:10 PM
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?
Answer by: Customer Support on Mar 30, 2026, 3:01 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?
Answer by: Customer Support on Aug 25, 2025, 8:45 AM
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.
