ZF 0501.339.711 MOTOR | OEM Genuine Part

Overview

The ZF 0501.339.711 MOTOR is a critical hydraulic drive component designed for integration within ZF heavy-duty transmission assemblies used in construction machinery. This OEM genuine part converts hydraulic pressure into mechanical rotational force, directly engaging the transmission’s gear train to enable vehicle movement. Positioned at the pump-to-transmission interface, the 0501.339.711 motor ensures precise torque delivery for demanding earthmoving and material handling applications. The SKU 0501.339.711 is manufactured to ZF’s exacting tolerances, guaranteeing seamless fitment and long service life in harsh operating environments.

Symptoms of Failure

• Intermittent gear slipping under load: When the 0501.339.711 motor wears, you may notice sudden loss of drive power during excavation or grading, often accompanied by erratic transmission response.
• Hydraulic oil leaks around the motor housing: Degraded seals or internal wear in the motor can cause visible fluid seepage at the mounting flange, leading to low system pressure and overheating.
• Unusual whining or grinding noises: A failing motor produces high-pitched sounds during operation, indicating internal bearing or gear damage that worsens with continued use.
• Delayed engagement or sluggish acceleration: Worn internal components reduce hydraulic flow, causing a noticeable lag when shifting from neutral to drive in wheel loaders or dozers.

Technical Specifications

Compatibility

This ZF 0501.339.711 motor is engineered for use in the following ZF transmission models commonly found in construction machinery: WG180, WG200, WG210, and WG250 series. It also fits select variants of the 4WG200 and 5WG210 transmissions used in wheel loaders, backhoe loaders, and telehandlers. Always verify your transmission serial number to confirm fitment.

When replacing the 0501.339.711 motor, it is essential to inspect companion components for wear. The 4699025039 GP25 gear pump supplies hydraulic flow to this motor, while the 4699101113 HOUSING encloses the motor assembly. Additionally, the 4699102157 INPUT shaft and 4699103114 OUTPUT flange must be checked for spline wear to prevent premature failure of the new motor.
