The Hydro-Gear PR-2HBC-GY1E-XXXX Hydraulic Pump (Right Side) is a genuine OEM PR Series 10cc hydraulic pump designed for high-performance SCAG Turf Tiger and compatible zero-turn mowers. Manufactured by Hydro-Gear, the original equipment manufacturer for SCAG hydraulic systems, this pump delivers the same factory-installed reliability, precision, and durability as the original unit.

Built for demanding commercial mowing applications, the PR Series pump provides smooth hydrostatic control, consistent torque delivery, and responsive maneuverability. Whether you're replacing a worn pump or restoring full drive performance, this OEM replacement ensures dependable operation under heavy workloads.

This model is specifically configured as the right-side hydraulic pump and replaces SCAG part number 483101. It is commonly used across a wide range of SCAG Turf Tiger models, including multiple deck sizes and engine configurations.

Because many zero-turn mowers use dual hydraulic pump systems, this unit is designed to replace only the right-side pump. Always confirm your configuration before ordering.

To ensure proper fitment, verify the Hydro-Gear part number stamped directly on your existing pump. For best results during installation, it is strongly recommended to flush hydraulic tanks and lines, install a new oil filter, and inspect or replace the wheel motor if needed. Contamination within the system is the leading cause of premature hydraulic pump failure.

This is a special order part and is non-returnable, so confirming compatibility before purchase is essential. For assistance, contact Carroll Stream Motor Company at (248) 628-4638.

These steps help prevent contamination and extend pump life.
