ZF 2094.303.044 SPLINED BUSH | OEM Genuine Part

Overview

The ZF 2094.303.044 SPLINED BUSH is a precision-engineered OEM genuine component designed to serve as a critical interface within the transmission’s rotating assembly. Positioned directly on the main shaft, this bushing absorbs torsional loads and maintains alignment between the gear train and the shift system. Its splined geometry ensures a secure, backlash-free connection, reducing wear on adjacent components. The SKU 2094.303.044 is manufactured to ZF’s exacting tolerances, guaranteeing a direct fit and long service life in demanding construction machinery applications.

Symptoms of Failure

• Transmission gear slipping under load: A worn splined bush can cause the main shaft to lose engagement with the gear hub, leading to intermittent power loss during operation.
• Metallic grinding noise from the transmission housing: As the bushing’s splines degrade, metal-on-metal contact occurs, producing a distinct grinding sound that worsens with acceleration.
• Oil contamination with metallic debris: Excessive bushing wear sheds fine metal particles into the transmission fluid, visible during routine oil changes as glitter-like residue.
• Vibration in the driveline at low speeds: Misalignment caused by a failing bush transfers uneven forces to the gearshift shaft, creating noticeable shuddering during gear engagement.

Technical Specifications

Compatibility

This splined bush is engineered for ZF’s heavy-duty powershift transmissions commonly found in wheel loaders, excavators, and dozers. It is a direct replacement for units in the WG180, WG200, and WG250 series. Additionally, it fits select 4WG-200 and 5WG-180 models used in construction machinery from OEMs such as Caterpillar, Volvo, and Liebherr. Always verify your transmission model and serial number before ordering.

When replacing the 2094.303.044, it is critical to inspect the 2094104412 MAIN SHAFT for wear, as a damaged bush can score the shaft surface. The 2094304054 MAIN SHAFT should also be checked for runout. For proper reassembly, ensure the 2094106010 SHIFT SYSTEM is aligned correctly, and the 2094206001 GEARSHIFT SHAFT moves freely within its bore. Neglecting these components can lead to premature bushing failure.
