ZF 4656.176.057 CLUTCH for WG 130/WG 160 | OEM Genuine Part

Overview

The ZF 4656.176.057 CLUTCH is a critical torque-transfer component engineered specifically for the WG 130 and WG 160 transmission series. Positioned within the clutch pack assembly, this OEM genuine part manages the engagement and disengagement of gear sets, ensuring smooth power delivery from the engine to the driveline. As a direct replacement for the original factory component, the SKU 4656.176.057 guarantees precise fitment and hydraulic compatibility, preventing premature wear on adjacent assemblies such as the 4656101023: TRANSMISSION HOUSING and the 4656201016: HOUS.FRONT SECT.

Symptoms of Failure

• Delayed or harsh gear engagement: When the clutch disc or piston wears, hydraulic pressure drops, causing noticeable lag or jarring shifts during acceleration.
• Transmission fluid leaks near the bell housing: Deteriorated seals on the 4656.176.057 clutch assembly allow ATF to escape, leaving puddles under the vehicle and reducing lubrication to the 4656301142: OIL TUBE.
• Slipping under load: Worn friction material fails to hold torque, resulting in engine RPM spikes without corresponding speed increase—especially common in WG 160 units.
• Burning odor or discolored fluid: Overheated clutch plates generate a distinct burnt smell and darken the transmission oil, indicating imminent failure of the 4656201029: HOUSING REAR PART seals.

Technical Specifications

Compatibility

This clutch is designed for the ZF WG 130 and WG 160 transmissions, which are commonly found in medium-duty trucks, buses, and construction equipment. It also fits select variants of the WG 180 and WG 200 series when used with the appropriate 0631306816: CYLINDRICAL PIN and 4656301148: FIXING PLATE. Always verify the clutch pack stack height against your transmission’s service manual to ensure proper clearance with the 0636102489: CAP SCREW and 4656301016: SCREEN SHEET.
