ZF 4699.170.148 MOTOR | OEM Genuine Part

Overview

The ZF 4699.170.148 MOTOR is a critical hydraulic drive component engineered for integration within ZF’s heavy-duty transmission assemblies used in construction machinery. This OEM genuine part serves as the primary power input unit, converting hydraulic pressure into mechanical torque to engage the transmission’s gear sets. Positioned at the interface between the pump and the gearbox, the 4699.170.148 motor ensures precise rotational control for loaders, excavators, and telehandlers. The SKU 4699.170.148 is factory-matched to ZF’s original specifications, guaranteeing seamless fitment and long-term reliability in high-cycle applications.

Symptoms of Failure

When the ZF 4699.170.148 motor begins to wear, operators often notice erratic gear engagement or delayed response when shifting between forward and reverse. A second common symptom is hydraulic oil leakage around the motor housing, typically caused by degraded seals or internal pressure spikes. Third, you may experience reduced machine travel speed under load, as the motor fails to maintain adequate torque output. Finally, unusual whining or grinding noises from the transmission area indicate bearing wear or internal scoring within the motor assembly. Addressing these issues promptly prevents cascading damage to adjacent components.

Technical Specifications

Compatibility

This motor is designed for use in ZF WG180, WG200, and WG250 series transmissions commonly found in construction machinery. It also fits select ERGO and Powershift models from ZF. Always verify your transmission model and serial number before ordering. For precise fitment, cross-reference the 4699.170.148 with your existing unit.

When replacing the motor, it is highly recommended to inspect and replace the 4699001185 GK10LD gear kit, as worn gears often accelerate motor failure. Additionally, the 4699101108 HOUSING should be checked for cracks or scoring. The 4699102172 INPUT shaft and 4699103057 OUTPUT flange are also common wear points that may require simultaneous replacement to ensure proper alignment and torque transfer.
