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 from the 420 Series, rated at 3.80 cubic inches per displacement (62cc). Built to handle high pressure and flow requirements, it supports a broad range of mobile equipment including loader backhoes, agriculture tractors, mini excavators, crawler dozers, and articulate haulers. Additional applications span container handling, railroad equipment, concrete and asphalt pavers, vibratory cable plows, and tunnel boring machinery.

The 420 Series platform offers fast response and recovery times alongside advanced control options that support efficient system management across variable duty cycles. With a product width of 5.75 inches, this pump is suited for integration into space-constrained mobile machine configurations. Its capacity and control flexibility make it a practical choice for utility boom trucks, rough terrain forklifts, feller/bunchers, and off-road dump and refuse vehicles.

Question by: Cody W on Jan 17, 2026, 10:06 AM
What kinda machines does this pump work on? I got a backhoe that needs fixin'.
Answer by: Customer Support on Jan 19, 2026, 6:50 AM
It's applicable to a good range of mobile equipment. Loader backhoes are definitely one of the applications, along with agriculture tractors, mini excavators, and crawler dozers.
Question by: Connie R on Nov 7, 2025, 12:30 PM
Got a mini excavator and a crawler dozer both needin' pump replacements, this 420 series unit, the 3.80 CID one, does it actually fit either of those applications or am I barkin up the wrong tree?
Answer by: Customer Support on Nov 8, 2025, 4:52 PM
Both of those machines are squarely in the supported application range for this pump. Mini excavators and crawler dozers are among the listed equipment types this 420 Series open circuit piston pump is built for, so you're not off base at all. The 62cc displacement and the high pressure and flow capacity it carries make it a practical match for the kind of variable duty cycles those machines put hydraulic systems through.
