Description

When your hydraulic system starts acting sluggish or you lose power to your three-point or loader, there’s a good chance your pump is starting to give out. This replacement hydraulic pump delivers the same 17 GPM flow rate your tractor needs to operate implements smoothly and keep up with demanding field work. It’s built to handle the constant pressure cycling that comes with running everything from loaders to three-point implements.

What You’re Getting

  • 17 GPM flow capacity that matches your tractor’s original performance specs
  • 2050 psi maximum pressure rating handles heavy loader work and implement operation
  • Direct replacement design fits without modifications or adapter plates
  • Built for continuous duty operation with robust internal components

Built for Real Farm Work

This pump is specifically designed for International Harvester’s hydrostatic transmission models including the Hydro 70, Hydro 86, and Hydro 186 tractors with serial numbers 12000 and up, plus the 666, 686, and Hydro 3488 models. These are the workhorses used for everything from feeding cattle and handling hay to running PTO implements and loader work around the farm.

Made to Last

Hydraulic pumps take a beating in farm service, constantly cycling under pressure while dealing with contaminated fluid and temperature swings. This replacement pump is built with quality materials and precision manufacturing to handle the demanding conditions your tractor faces every day, from early morning chores to long harvest days.

Installation Notes

Installation requires draining the hydraulic system and typically takes 2-3 hours for an experienced mechanic. Always use clean hydraulic fluid and change your filters when installing a new pump to protect your investment. Prime the pump with fresh fluid before startup and check all connections for leaks after installation.
