ZF 4644.306.324 BUSH for WG180/WG200/WG201 | OEM Genuine Part

Overview

The ZF 4644.306.324 BUSH is a precision-engineered wear component designed for the clutch and gear train assemblies within the WG180, WG200, and WG201 series transmissions. This OEM genuine part, identified by SKU 4644.306.324, serves as a critical bearing surface, reducing friction between rotating shafts and stationary housings. It is typically pressed into the TRANSMISSION HOUSING to support the output shaft, ensuring concentric alignment and smooth power transfer. Without this bushing, metal-on-metal contact would accelerate wear and degrade shift quality.

Symptoms of Failure

• Oil seepage around the output flange area: A worn 4644.306.324 bushing can cause misalignment, leading to seal distortion and hydraulic fluid leaks near the OUTPUT FLANGE.
• Gear slipping under load: Excessive radial play from a degraded bushing allows the shaft to wobble, resulting in intermittent power loss during acceleration.
• Metallic grinding noise from the transmission housing: As the bushing material erodes, steel-on-steel contact generates a distinct whine or grind, particularly in neutral or low gear.
• Vibration at the DISCONNECTION point: A failing bushing introduces axial play that transmits vibration through the driveline, often felt in the chassis during gear changes.

Technical Specifications

Compatibility

This bushing is engineered for the ZF WG180, WG200, and WG201 series transmissions. It is a direct fit for models requiring a replacement of the shaft support bushing within the main housing. The 4644.306.324 is commonly used in conjunction with the HEXAGON SCREW for secure mounting and the TRANSMISSION HOUSING for structural integrity. Always verify your transmission serial number against ZF specifications before installation.
