ZF 4699.170.152 MOTOR | OEM Genuine Part

Overview

The ZF 4699.170.152 MOTOR is a critical hydraulic actuation component within ZF heavy-duty powershift transmissions, specifically engineered for construction machinery applications. This OEM genuine part converts hydraulic pressure into precise mechanical motion to engage clutch packs and shift gears. Positioned within the transmission valve body or directly on the clutch housing, the 4699.170.152 motor ensures reliable torque delivery during demanding operations like earthmoving and material handling. The SKU 4699.170.152 is manufactured to ZF’s exacting tolerances, guaranteeing seamless integration with the 4699100019: BASIC PARTS assembly and the 4699300139: HOUSING unit.

Symptoms of Failure

• Intermittent gear engagement delay — When the motor wears, you may notice a 2-3 second lag between shifting and actual gear engagement, especially under load. This “delayed shift response” is a common long-tail search query among fleet managers.
• Hydraulic fluid contamination — A failing motor can shed metallic debris into the transmission oil, leading to “clutch slip due to contaminated fluid.” This often accompanies erratic shifting patterns.
• Unusual whining or grinding noises — Worn internal seals or bearings cause “transmission whine during acceleration,” particularly in ZF WG180 and WG200 series units.
• Complete loss of forward or reverse — In advanced failure, the motor seizes, resulting in “no drive in any gear” — a critical symptom requiring immediate replacement.

Technical Specifications

Compatibility

This motor is designed for ZF WG series transmissions commonly used in construction machinery. It is a direct fit for the WG180 and WG200 series, as well as the WG150 and WG250 models. The 4699.170.152 interfaces directly with the 4699300156: GEAR SHAFT and the 4699300127: PLANET CARRIER to ensure synchronized clutch pack engagement. Always verify your transmission model tag before ordering.
