ZF 2074.311.009 BUSH | OEM Genuine Part

Overview

The ZF 2074.311.009 BUSH is a precision-engineered OEM genuine component designed to function as a critical wear surface within the planetary gearset of heavy-duty ZF transmissions. This bushing reduces friction between rotating shafts and stationary housings, ensuring smooth torque transfer in construction machinery applications. The SKU 2074.311.009 is specifically manufactured to maintain tight clearances, preventing axial play that can compromise gear alignment. It sits directly inside the TRANSMISSION HOUSING and works in conjunction with the HOUSING to support load-bearing shafts. Without this bushing, the entire assembly would experience accelerated wear on surrounding components like the HOUSING and COVER.

Symptoms of Failure

• Transmission whining noise under load – A high-pitched metallic sound during acceleration indicates the bushing has worn beyond tolerance, allowing shaft-to-housing contact.
• Oil seepage around the housing joint – Worn bushings create excessive clearance, forcing lubricant past the O-RING and GASKET seals.
• Intermittent gear engagement delay – When the bushing loses its dimensional stability, the shaft can shift slightly, causing hesitation when shifting between forward and reverse.
• Vibration in the driveline at low RPM – A worn 2074.311.009 bushing fails to dampen torsional vibrations, transmitting shudder through the TRANSMISSION HOUSING.

Technical Specifications

Compatibility

This bushing is engineered for ZF power shift transmissions commonly used in wheel loaders, dozers, and graders. It is a direct fit for the WG180, WG200, and WG210 series. Additionally, it appears in certain 4WG-200 and 6WG-200 variants where the planetary carrier requires a replaceable wear surface. Always verify the bushing bore condition in the HOUSING before installation. For shaft sealing, pair this bushing with a SHAFT SEAL to prevent contamination.
