ZF 4699.170.131 MOTOR | OEM Genuine Part

Overview

The ZF 4699.170.131 MOTOR is a critical hydraulic drive component engineered for demanding construction machinery applications. This OEM genuine part converts hydraulic pressure into precise rotational torque, directly powering the transmission’s pump drive system. Positioned within the driveline assembly, the 4699.170.131 motor interfaces with the 4699001162: GK10LD gearbox to regulate output speed and load handling. As a factory-spec replacement, it ensures seamless integration with your ZF transmission, eliminating the risk of premature wear caused by aftermarket alternatives. The SKU 4699.170.131 is laser-etched on the housing for quick verification during installation.

Symptoms of Failure

• Intermittent torque loss under load – When the motor’s internal seals degrade, you may notice the machine struggling to maintain traction on inclines or during heavy digging cycles.
• Hydraulic fluid contamination – Worn piston rings allow metal debris to enter the oil circuit, causing dark, gritty fluid that accelerates damage to the 4699101108: HOUSING and adjacent valves.
• Abnormal whining or grinding noises – Bearing failure inside the motor produces a high-pitched whine during rotation, often escalating to a grinding sound as the 4699102172: INPUT shaft wears against the housing.
• Slow or jerky transmission response – A failing motor cannot maintain consistent flow, leading to delayed engagement when shifting between forward and reverse gears.

Technical Specifications

Compatibility

This motor is designed for ZF’s WG180, WG200, and WG210 series transmissions commonly used in wheel loaders, excavators, and telehandlers. It directly replaces the original unit in models such as the ZF WG180-3 and WG200-5. For proper fitment, verify that your transmission’s 4699103058: OUTPUT flange matches the motor’s mounting pattern. Always pair this motor with a new 0634306309: O-RING and 0630513065: SNAP RING to prevent fluid bypass during reassembly.
