ZF 2094.324.007 BUSH | OEM Genuine Part

Overview

The ZF 2094.324.007 BUSH is a precision-engineered OEM genuine part designed to function as a critical wear surface within the planetary gearset and shaft support assemblies of heavy-duty construction machinery transmissions. This bushing reduces friction between rotating components, ensuring precise alignment and load distribution under extreme torque conditions. The SKU 2094.324.007 is specifically manufactured to ZF’s exacting tolerances, making it an essential replacement for maintaining drivetrain integrity in demanding off-highway applications.

Symptoms of Failure

• Transmission whining or grinding noise during gear engagement: A worn 2094.324.007 bushing allows excessive radial play, causing metal-on-metal contact that produces audible high-pitched sounds, especially under load.
• Oil pressure fluctuations or low-pressure warnings: As the bushing wears, it can obstruct internal oil galleries, leading to inconsistent lubrication pressure and potential overheating of adjacent components.
• Vibration through the chassis during acceleration: Degraded bushing material fails to dampen rotational harmonics, transmitting vibration from the main shaft assembly to the transmission housing.
• Delayed or harsh shifting in forward/reverse gears: Excessive clearance from a worn bushing disrupts the precise axial positioning required for proper clutch pack engagement.

Compatibility

This bushing is a direct replacement for ZF WG180, WG200, and WG210 series transmissions commonly used in wheel loaders, telehandlers, and graders. It is also found in select ZF 4WG-200 and 6WG-200 powershift models. For proper fitment, always verify the bushing position within the main shaft support bore.

Installation Context

When replacing the 2094.324.007 BUSH, it is standard practice to inspect and often replace the 2094104412: MAIN SHAFT and the 2094304054: MAIN SHAFT to ensure concentricity. The 2094106010: SHIFT SYSTEM and 2094206001: GEARSHIFT SHAFT should also be evaluated for wear, as bushing degradation often damages these mating components.

Frequently Asked Questions

Q: How do I know if the 2094.324.007 bushing is the correct size for my ZF transmission?
A: Measure the inner diameter of the housing bore and the outer diameter of the mating shaft. This bushing fits a 45mm shaft with a 55mm housing bore. Always cross-reference your transmission model (WG180/WG200) with the OEM parts catalog.

Q: Can I reuse the old snap ring when installing this bushing?
A: No. The snap ring (part 0630513070) should always be replaced, as it loses tension over time and can allow the bushing to walk out of position.

Q: What causes premature bushing wear in construction machinery transmissions?
A: Common causes include contaminated hydraulic fluid (abrasive particles), low oil levels causing boundary lubrication, or misalignment from a bent main shaft. Always inspect the 2094104412 MAIN SHAFT for runout during replacement.
