Product Overview

John Deere R79152 Hydraulic Pump Shaft


OEM Replacement John Deere R79152 Hydraulic Pump Drive Shaft


The John Deere R79152 Hydraulic Pump Shaft is a precision-machined power transmission component designed for John Deere tractor hydraulic pump systems. This shaft connects the pump drive mechanism to the hydraulic pump, transmitting engine power efficiently and ensuring stable hydraulic pressure throughout the machine.

As a critical component of the hydraulic system, the R79152 pump shaft directly affects the performance of steering systems, hydraulic remotes, three-point hitch functions, loaders, and auxiliary hydraulic circuits. A worn or damaged pump shaft can result in reduced hydraulic efficiency, power loss, abnormal noise, and premature pump failure.

Manufactured from premium heat-treated alloy steel, the John Deere R79152 hydraulic pump shaft offers exceptional torsional strength, wear resistance, and durability for continuous agricultural operation.

Dawopu manufactures and supplies OEM-quality hydraulic pump components for John Deere tractors and agricultural machinery worldwide.
