ZF 4699.170.038 MOTOR | OEM Genuine Part

Overview

The ZF 4699.170.038 MOTOR is a critical hydraulic drive component engineered for demanding construction machinery applications. This OEM genuine part serves as the primary power input unit within ZF transmission assemblies, converting hydraulic flow into precise rotational torque to drive the gear train. Positioned at the transmission’s input flange, the 4699.170.038 motor interfaces directly with the pump system and the 4699100019: BASIC PARTS kit to ensure seamless power delivery. When paired with the 4699300139: HOUSING, this motor maintains proper alignment and pressure containment, making it indispensable for loader, excavator, and grader transmissions.

Symptoms of Failure

When the ZF 4699.170.038 motor begins to wear, operators often notice distinct performance issues. Hydraulic motor hesitation or sluggish response during acceleration is a common early sign, particularly in cold-start conditions. External oil seepage around the motor shaft seal indicates seal degradation, leading to gradual fluid loss and reduced system pressure. Unusual whining or grinding noises from the transmission input area suggest bearing wear or internal scoring. Finally, intermittent gear slipping under load—especially when climbing grades or lifting heavy materials—points to insufficient torque output from a failing motor. Addressing these symptoms promptly prevents cascading damage to the 4699300156: GEAR SHAFT and other driveline components.

Technical Specifications

Compatibility

This OEM genuine motor is designed for integration with ZF’s heavy-duty transmission families commonly found in construction machinery. It is a direct fit for the ZF WG180 and WG200 series transmissions, as well as the ZF 4WG-200 and 5WG-200 variants. The 4699.170.038 also supports select ZF Ergopower and ZF Ecolite models used in wheel loaders and telehandlers. For proper assembly, this motor works in conjunction with the 4699300127: PLANET CARRIER to distribute torque evenly across the planetary gearset. Always verify your transmission model’s serial number before ordering.
