ZF 2093.303.024 FLANGE BUSH | OEM Genuine Part

Overview

The ZF 2093.303.024 FLANGE BUSH is a precision-machined OEM genuine component designed to provide a stable bearing surface and precise alignment within heavy-duty ZF transmission assemblies. This bushing sits at the interface between rotating shafts and stationary housings, reducing friction and maintaining concentricity under high torque loads. Commonly found in construction machinery drivelines, the SKU 2093.303.024 ensures that power transfer remains smooth and that adjacent components like the 5838109012: DIFFERENTIAL and the 0750117075: TAPER ROLLER BEARING operate within their designed tolerances.

Symptoms of Failure

• Transmission whining or grinding noise under load: When the flange bushing wears, metal-to-metal contact creates a distinct high-pitched sound, especially during acceleration or when turning.
• Oil seepage around the shaft seal area: A worn bushing allows excessive shaft movement, breaking the seal integrity and causing slow, persistent fluid leaks from the transmission housing.
• Vibration in the driveline during low-speed operation: Loss of bushing clearance leads to shaft wobble, which transmits noticeable vibration through the chassis and into the operator cab.
• Premature wear on the differential housing bore: A failing bushing can damage the mating surface of the 5838300626: DIFFERENTIAL HOUSING, requiring costly repairs beyond a simple bushing replacement.

Technical Specifications

Compatibility

This flange bushing is engineered for ZF heavy-duty powershift transmissions commonly used in wheel loaders, graders, and excavators. Based on its design and dimensions, it is compatible with the following ZF transmission models: WG180, WG200, WG210, and WG310. It also integrates directly with the 2093209023: DIFFERENTIAL assembly, ensuring proper shaft alignment and load distribution across the entire gear train.

Frequently Asked Questions

Q: How do I know if the 2093.303.024 flange bush needs replacement?
A: Listen for a rhythmic knocking or whining sound from the transmission area, especially when shifting from forward to reverse. Also check for oil residue near the shaft seal—if present, inspect the bushing immediately.

Q: Can I reuse the old flange bush if it looks only slightly worn?
A: No. ZF recommends always replacing this bushing during any differential or transmission overhaul. Even minor wear alters shaft alignment and accelerates damage to the 5838300626: DIFFERENTIAL HOUSING.

Q: Is this bushing compatible with aftermarket differentials?
A: The 2093.303.024 is designed specifically for OEM ZF assemblies. For best results, pair it with genuine ZF components such as the 2093209023: DIFFERENTIAL to guarantee proper fit and load capacity.
