Product Questions & Answers

Running a crawler dozer on a pretty rough job site, been looking at this pump for a replacement. That 80 cc displacement, is that gonna hold up for that kind of heavy-duty work?

Question by: Hubert S on May 4, 2025, 7:02 PM

Crawler dozers are actually listed as one of the core applications for this pump, so you're in the right ballpark. The 420 Series platform is built around high pressure and flow capacity, which is what you need when load conditions are shifting constantly on uneven ground. The open circuit piston design handles the kind of variable demand that dozer work throws at it without a lot of drama.

Hey, will this fit on my older Eaton 421A? Just want to make sure before I order.

This Danfoss/Eaton pump is a direct replacement for the 420 series, including the older 421A models. You shouldn't have any fitment issues.
