ZF 0730.061.913 BUSH | OEM Genuine Part

Overview

The ZF 0730.061.913 BUSH is a precision-engineered OEM genuine component designed to serve as a critical wear surface within the transmission assembly of heavy-duty construction machinery. This bushing reduces friction between rotating shafts and stationary housings, ensuring smooth torque transfer and extending the lifespan of adjacent components. The SKU 0730.061.913 is specifically manufactured to ZF’s exacting tolerances, providing a direct replacement that maintains factory-specified clearances. It is typically installed inside the TRANSMISSION HOUSING and works in concert with the HOUSING to support gear shafts under high load conditions.

Symptoms of Failure

When the ZF 0730.061.913 bushing wears beyond its service limits, operators will notice distinct performance issues. Look for these specific failure symptoms:

• Oil leaks around shaft seals: A worn bushing allows excessive shaft movement, compromising seal integrity and causing transmission fluid to weep from the housing interface.
• Gear slipping under load: Increased radial play from a degraded bushing can misalign gears, leading to intermittent power loss during excavation or hauling operations.
• Metallic grinding noises: When the bushing material erodes, metal-to-metal contact between the shaft and housing produces a distinct high-pitched whine or grinding sound during gear changes.
• Vibration in the driveline: Excessive clearance from bushing wear creates harmonic vibrations that can be felt through the chassis, particularly at low RPMs.

Technical Specifications

Compatibility

This bushing is engineered for use in ZF’s heavy-duty powershift transmission series commonly found in construction machinery. It is compatible with the following transmission models:

• ZF WG180
• ZF WG200
• ZF WG210
• ZF WG310
• ZF WG311

During installation, ensure the TYPE PLATE is correctly aligned to confirm the transmission variant, and use a GROOVED STUD to secure the housing assembly. Always replace the bushing in pairs when servicing both sides of a shaft.
