ZF 4699.170.240 MOTOR | OEM Genuine Part

Overview

The ZF 4699.170.240 MOTOR is a critical hydraulic drive component engineered for demanding construction machinery applications. Positioned within the transmission’s hydraulic control circuit, this OEM genuine part converts fluid pressure into mechanical torque to actuate clutch packs and valve assemblies. The SKU 4699.170.240 identifies a precision-machined motor unit that interfaces directly with the transmission housing and input shaft. When installed alongside the 4699027011 GP25 gear pump, it ensures consistent oil flow and pressure regulation. This motor is designed to withstand high cyclic loads and operates within a sealed environment to prevent contamination.

Symptoms of Failure

• Erratic clutch engagement or delayed shifting – A worn 4699.170.240 motor can cause inconsistent hydraulic pressure, leading to gear slipping or harsh engagement during load cycles.
• Audible whining or grinding from the transmission – Internal wear on the motor’s rotor or bearings produces metallic noises, especially under heavy load or at low RPM.
• Hydraulic fluid leaks near the motor housing – Degraded seals or cracked casing around the motor result in visible oil seepage, reducing system efficiency and risking contamination.
• Reduced machine travel speed or power – A failing motor fails to deliver adequate torque, causing sluggish acceleration or inability to maintain grade on inclines.

Technical Specifications

Compatibility

This motor is engineered for ZF’s heavy-duty powershift transmission series, including the WG180, WG200, and WG250 models commonly used in wheel loaders, graders, and excavators. It also fits select 4WG200 and 6WG200 variants. The 4699.170.240 motor mounts directly to the 4699101099 HOUSING and receives hydraulic input from the 4699102099 INPUT shaft assembly. For proper torque transfer, it must be paired with the 4699103045 OUTPUT coupling. Always verify your transmission model’s serial number before ordering.
