Hydro-Gear 116-2444 Hydraulic Pump Assembly

The Hydro-Gear PK-BGAB-EY1X-XXXX is a fixed-displacement axial piston hydraulic pump designed for hydrostatic drive systems in commercial zero-turn mowers. It features precision-machined internal components, rugged cast-aluminum housing, and integrated charge pump for reliable operation under continuous high-pressure cycles. This unit serves as direct OEM replacement for Toro part numbers 116-2444 and 103-7262, and Exmark 116-2444. It is compatible with Hydro-Gear BDP-10A and PR-series (BDP-16A) transaxle configurations. The pump delivers consistent flow and pressure for responsive steering and traction control in demanding landscaping applications. Cross-references include Hydro-Gear PJ-BGAB-EY1X-XXXX and PK-BGAB-EY1X-XXXX manufacturer part numbers. Installation requires verification of serial number ranges for specific Exmark Lazer Z and Toro Z Master models to ensure correct port orientation and displacement matching.
