ZF 4699.170.117 MOTOR | OEM Genuine Part

Overview

The ZF 4699.170.117 MOTOR is a critical hydraulic actuation component within ZF powershift transmissions, specifically engineered to control clutch pack engagement in heavy-duty construction machinery. This OEM genuine part converts hydraulic pressure into precise mechanical motion, ensuring smooth gear shifts under extreme load conditions. The SKU 4699.170.117 is a direct replacement unit that interfaces directly with the 4699101090: HOUSING assembly, where it regulates oil flow to the clutch pistons. Without this motor, the transmission cannot modulate gear ratios, making it essential for loaders, graders, and excavators operating in demanding environments.

Symptoms of Failure

• Delayed or harsh gear engagement – When the 4699.170.117 motor loses internal sealing, hydraulic pressure drops, causing a noticeable lag or jarring shift when moving from neutral to forward/reverse.
• Transmission overheating under load – A failing motor can cause constant clutch slippage, generating excessive heat that triggers warning lights or reduces machine performance.
• Intermittent loss of drive – Worn internal components may cause the motor to stick, resulting in sudden loss of power to the wheels, especially during incline operations.
• Hydraulic oil contamination – Debris from a deteriorating motor can migrate into the 0634306309: O-RING seals and 0637885612: BREATHER, leading to system-wide contamination and accelerated wear.

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, WG200, and WG250 models. The 4699.170.117 also appears in select WG120 and WG150 variants where the clutch housing configuration matches. Always verify the 0501329881: HOUSING COVER alignment before installation, as cover tolerances vary between transmission series.
