ZF 0730.260.792 BUSH for WG90/WG94 | OEM Genuine Part

Overview

The ZF 0730.260.792 BUSH is a precision-engineered wear component designed for the WG90 and WG94 series transmissions. This OEM genuine part functions as a sacrificial bearing surface, reducing friction between rotating shafts and stationary housings within the gear train assembly. Installed directly inside the TRANSMISSION HOUSING, it ensures proper shaft alignment and load distribution during high-torque operations. The SKU 0730.260.792 is manufactured to ZF’s exacting tolerances, guaranteeing a seamless fit that prevents metal-to-metal contact and extends the service life of adjacent components.

Symptoms of Failure

• Oil leaks near the housing interface: A worn 0730.260.792 bushing allows pressurized transmission fluid to bypass the seal, causing visible drips or wet spots around the HOUSING.
• Gear slipping under load: Excessive bushing clearance leads to shaft misalignment, resulting in intermittent power loss or delayed engagement during acceleration.
• Metallic grinding noises: As the bushing wears thin, steel-on-steel contact produces a distinct whining or grinding sound, particularly in lower gears.
• Vibration in the driveline: Worn bushings fail to dampen rotational forces, transmitting noticeable shudder through the chassis at highway speeds.

Technical Specifications

Compatibility

This bushing is specifically engineered for ZF WG90 and WG94 series transmissions, including models such as WG180, WG200, and WG210. It also fits select WG92 variants used in mid-range commercial vehicles. For proper installation, ensure the TUBE is free of burrs and the CYLINDRICAL PIN is correctly aligned to prevent premature wear.
