Question by: Howard W on Jan 15, 2026, 9:08 AM
Been running a crawler dozer for years and the original pump finally gave out. This a 420 Series open circuit piston pump with 3.80 CID displacement -- that the right ballpark for that kind of machine?
Answer by: Customer Support on Jan 16, 2026, 1:35 PM
Crawler dozers are one of the listed applications for this pump, so you're in the right territory. The 3.80 CID (62cc) displacement puts it in a solid range for that class of machine, and the 420 Series is built around high pressure and flow capacity, which lines up with what a dozer demands. If your original pump matched that displacement and code configuration, this would be a reasonable replacement candidate.

Is this pump a direct swap for the Eaton 420 Code B series?
Answer by: Customer Support on Jan 5, 2026, 6:22 AM
Use-case-first: For mobile hydraulic applications like loader backhoes and tractors, this Danfoss/Eaton 420 series pump should work as a replacement, given that it is the same 420 Code B series.
