ZF 4699.170.064 MOTOR | OEM Genuine Part

Overview

The ZF 4699.170.064 MOTOR is a critical hydraulic drive component engineered for integration within ZF’s heavy-duty powershift transmission assemblies, specifically those used in construction machinery. This OEM genuine part converts hydraulic pressure into mechanical torque to actuate clutch packs or shift elements inside the gearbox. The SKU 4699.170.064 is a direct replacement unit designed to restore precise oil flow control and ensure consistent engagement under high load conditions. It mounts directly onto the valve body or housing interface, acting as the final actuator for gear selection in wheel loaders, graders, and dozers.

Symptoms of Failure

When the ZF 4699.170.064 motor begins to degrade, operators often notice delayed gear engagement or sluggish shifting under load, a common long-tail search query for worn actuators. Another frequent failure sign is intermittent transmission slippage during acceleration, caused by insufficient hydraulic pressure reaching the clutch packs. You may also observe erratic or harsh shifting as the motor fails to modulate oil flow smoothly. In advanced cases, internal hydraulic leaks can occur, leading to low system pressure and eventual transmission overheating.

Technical Specifications

Compatibility

This motor is primarily used in ZF WG180, WG200, and WG210 series transmissions commonly found in construction machinery. It also fits select 4WG-200 and 6WG-200 variants used in articulated dump trucks and telehandlers. Always verify the housing interface pattern before installation. This part works in conjunction with the 4699100019: BASIC PARTS kit, which includes necessary seals and snap rings for a complete rebuild. The motor mounts directly into the 4699300139: HOUSING, which provides the fluid passages. Torque from the motor is transmitted through the 4699300156: GEAR SHAFT, while the 4699300127: PLANET CARRIER supports the final drive reduction.
