ZF 4699.170.111 MOTOR | OEM Genuine Part

Overview

The ZF 4699.170.111 MOTOR is a critical hydraulic drive component engineered for demanding construction machinery applications. This OEM genuine part converts fluid pressure into mechanical rotational force, directly engaging the transmission’s geartrain to propel the vehicle. Positioned within the driveline assembly, the motor interfaces with the 4699101095: HOUSING to ensure precise torque delivery. The SKU 4699.170.111 is manufactured to ZF’s exacting tolerances, guaranteeing seamless integration with the transmission’s internal oil circuits and load-bearing structures.

Symptoms of Failure

• Intermittent drive loss under load – The motor fails to maintain consistent torque when the machine encounters heavy resistance, often accompanied by a whining noise from the transmission housing.
• Hydraulic oil contamination – Worn internal seals allow debris to enter the fluid circuit, visible as metallic particles in the oil filter or sump magnet.
• Erratic speed control – The motor surges or hesitates during low-speed maneuvering, indicating internal wear on the rotor or valve plate.
• External fluid seepage – Oil weeping from the motor-to-housing interface, typically requiring replacement of the 0634306309: O-RING alongside the motor.

Technical Specifications

Compatibility

This motor is engineered for ZF’s WG series powershift transmissions commonly used in wheel loaders, telehandlers, and excavators. It is directly compatible with the WG180, WG200, and WG210 models. The unit also integrates with the 0501329881: HOUSING COVER and requires proper venting via the 0637885612: BREATHER to prevent pressure buildup. For complete driveline restoration, verify the motor’s alignment with the output shaft and turntable bearing specifications.
