ZF 0730.161.277 BUSH for WG181 | OEM Genuine Part

Overview

The ZF 0730.161.277 BUSH for WG181 is a precision-engineered OEM genuine component designed to serve as a critical wear surface within the planetary gearset assembly of heavy-duty ZF transmissions. This bushing, identified by SKU 0730.161.277, is installed directly inside the TRANSMISSION HOUSING to support rotating shafts and reduce friction between moving parts. By maintaining correct shaft alignment and load distribution, this bushing ensures smooth torque transfer and extends the service life of the entire gear train. It is a direct-fit replacement for the WG 181 Series, guaranteeing OEM tolerances and material integrity.

Symptoms of Failure

When the ZF 0730.161.277 bushing wears out, operators may notice distinct performance issues. Look for these specific failure symptoms to diagnose a worn bushing:

• Oil leaks around the housing interface: A degraded bushing can cause seal misalignment, leading to transmission fluid seepage near the HOUSING joint.
• Gear slipping under load: Excessive radial play from a worn bushing allows the shaft to shift, causing intermittent gear disengagement during acceleration.
• Metallic grinding noises: As the bushing material erodes, metal-to-metal contact between the shaft and housing produces a distinct grinding sound during operation.
• Vibration in the driveline: Loss of bushing integrity introduces shaft wobble, resulting in noticeable vibration at highway speeds.

Technical Specifications

Compatibility

This bushing is engineered for the ZF WG 181 Series transmission family. Based on its design and application, it is also compatible with the following ZF models that share similar planetary gearset architecture: WG180, WG200, and WG211. Always verify fitment against your transmission’s serial number and housing configuration before installation.
