ZF 4657.176.027 CLUTCH for WG 190/WG 210 | OEM Genuine Part

Overview

The ZF 4657.176.027 CLUTCH is a critical torque-transfer component engineered specifically for the WG 190 and WG 210 series transmissions. Positioned within the planetary gear set assembly, this OEM genuine part manages the engagement and disengagement of power flow between the input shaft and the intermediate shaft. The SKU 4657.176.027 is a direct replacement for worn units, ensuring precise hydraulic actuation and minimal power loss during gear changes. This clutch pack works in concert with the 4657101049: TRANSMISSION HOUSING to maintain structural alignment under high torque loads.

Symptoms of Failure

• Delayed engagement or gear slipping under load: When the friction discs wear thin, the clutch fails to lock up completely, causing the transmission to slip during acceleration or hill climbs.
• Erratic shift timing and harsh engagements: Worn seals or scored steel plates lead to inconsistent hydraulic pressure, resulting in jarring shifts or delayed gear changes.
• Contaminated transmission fluid with metallic debris: As the clutch material degrades, fine metal particles circulate through the oil, often visible during routine fluid changes.
• Overheating and burnt oil smell: Slipping generates excessive friction heat, which oxidizes the transmission fluid and produces a distinct burnt odor.

Technical Specifications

Compatibility

This clutch assembly is a direct fit for ZF WG 191 series transmissions and is also compatible with the WG 180, WG 190, WG 200, and WG 210 models. It integrates with the 4657301130: HOUS.FRONT SECT and the 4657301131: HOUSING REAR PART to form the complete clutch drum assembly. Proper installation requires the 0631306816: CYLINDRICAL PIN for precise alignment of the clutch pack within the drum.
