ZF 4660.305.027 BUSH for WG92 | OEM Genuine Part

Overview

The ZF 4660.305.027 BUSH is a precision-engineered wear component designed for the WG 92 Series transmission family. This OEM genuine part functions as a critical bearing surface within the transmission housing assembly, reducing friction between rotating shafts and stationary components. Installed directly inside the TRANSMISSION HOUSING, this bushing ensures proper shaft alignment and load distribution during high-torque operations. The SKU 4660.305.027 is manufactured to ZF’s exacting tolerances, guaranteeing a seamless fit and extended service life in heavy-duty industrial applications.

Symptoms of Failure

• Oil leaks around the transmission housing: When the 4660.305.027 bushing wears, it can cause misalignment that stresses seals, leading to fluid seepage near the HOUSING II interface.
• Gear slipping under load: Excessive bushing clearance allows shaft play, resulting in intermittent power loss or delayed engagement during acceleration.
• Metallic grinding or whining noises: Worn bushings permit metal-on-metal contact, producing audible sounds that intensify with transmission temperature.
• Vibration in neutral or drive: Degraded bushings fail to dampen torsional vibrations, causing noticeable shaking through the drivetrain.

Technical Specifications

Compatibility

This bushing is engineered for the ZF WG 92 Series, including models such as WG92, WG120, WG150, WG180, and WG200. It is a direct replacement for transmissions used in construction equipment, agricultural machinery, and material handling vehicles. The 4660.305.027 interfaces with the CYLINDRICAL PIN for precise alignment and is secured by the TYPE PLATE for identification. Always verify your transmission serial number against ZF’s parts catalog before ordering.
