ZF 0730.103.288 THRUST WASHER | OEM Genuine Part

Overview

The ZF 0730.103.288 THRUST WASHER is a precision-engineered OEM genuine component designed to manage axial loads and maintain critical clearances within ZF heavy-duty transmissions. Positioned between rotating shafts and stationary housings, this hardened steel washer absorbs end-play forces that would otherwise cause metal-on-metal contact and premature wear. The SKU 0730.103.288 is specifically calibrated for use in construction machinery transmissions, ensuring that gear sets remain properly aligned under extreme torque and vibration. When installed alongside a TRANSMISSION HOUSING, this thrust washer provides the necessary bearing surface to prevent scoring and maintain hydraulic pressure integrity.

Symptoms of Failure

• Transmission gear slipping under load: A worn 0730.103.288 allows excessive axial movement, causing gears to lose engagement during heavy operation.
• Metallic grinding noise from the clutch pack area: As the thrust washer surface degrades, steel particles contaminate the oil, creating audible friction sounds.
• Erratic shift timing or delayed engagement: Increased end-play disrupts the precise hydraulic balance required for smooth clutch application.
• Low transmission oil pressure warnings: A collapsed or worn washer can misalign the HOUSING, leading to internal oil leakage and pressure drops.

Technical Specifications

Compatibility

This thrust washer is a direct fit for ZF WG180, WG200, and WG250 series transmissions commonly used in wheel loaders, excavators, and telehandlers. It also applies to select ZF 4WG-200 and 6WG-200 models where axial thrust loads are present on the input shaft or planetary carrier. For proper installation, always pair this washer with a new HOUSING and COVER to ensure correct preload and sealing.
