ZF 4699.170.254 MOTOR | OEM Genuine Part

Overview

The ZF 4699.170.254 MOTOR is a critical hydraulic drive component engineered for precise power delivery within ZF construction machinery transmissions. This OEM genuine part converts hydraulic pressure into mechanical rotation, directly engaging the transmission’s gear train to control vehicle movement. Located within the valve body assembly, the motor regulates fluid flow to modulate clutch engagement and torque output. The SKU 4699.170.254 is specifically designed to meet ZF’s exacting tolerances, ensuring seamless integration with the transmission’s hydraulic circuit. When paired with the 4699025169 GP25 gear pump, this motor forms the core of the transmission’s actuation system, delivering consistent performance under heavy loads.

Symptoms of Failure

• Intermittent gear slipping under load: A worn motor fails to maintain hydraulic pressure, causing the transmission to lose torque during excavation or lifting operations.
• Delayed or harsh shifting: Reduced motor efficiency leads to sluggish clutch engagement, often accompanied by audible grinding noises.
• External hydraulic fluid seepage: Degraded seals around the motor shaft allow oil to escape, leaving visible puddles beneath the equipment.
• Overheating transmission fluid: A failing motor increases internal friction, raising operating temperatures and accelerating fluid degradation.

Technical Specifications

Compatibility

This motor is engineered for ZF’s heavy-duty transmission families used in construction machinery. It is a direct fit for the WG180 and WG200 series, commonly found in wheel loaders, excavators, and telehandlers. The part also integrates with the WG250 and WG310 transmissions when used in conjunction with the 4699101153 HOUSING adapter. For complete assembly, the motor must be paired with the 4699102130 INPUT shaft and the 4699103122 OUTPUT flange to ensure proper torque transfer and alignment.
