If I'm running this thing pretty hard, what kinda upkeep should I expect?

Maintenance intervals will depend heavily on your specific application and operating conditions, but generally keeping an eye on fluid cleanliness and performing regular inspections of the pump housing and connections is advisable. This helps ensure optimal performance and longevity.

Got a 420 series piston pump on a crawler dozer that's been giving me grief with slow response times. This here a direct fit for that kind of application?

Question by: Shane E on Feb 10, 2026, 12:38 PM

Crawler dozers are actually one of the listed applications for this pump, so you're in the right ballpark. The 420 Series is built around fast response and recovery times, which is exactly the kind of thing that makes a difference when you're pushing loads and need the hydraulics to keep up. The open circuit piston design handles the demands that come with that type of heavy equipment work.
