ZF 0730.100.289 THRUST WASHER for WG200 | OEM Genuine Part

Overview

The ZF 0730.100.289 THRUST WASHER is a precision-engineered OEM genuine component designed specifically for the WG200 series transmission. This hardened steel washer sits between rotating shafts and stationary housings within the planetary gear set, absorbing axial loads and maintaining critical clearances. As part of the oil pump drive assembly, it prevents metal-on-metal contact that would otherwise lead to premature gear wear. The SKU 0730.100.289 is manufactured to ZF’s exacting tolerances, ensuring consistent oil film thickness and torque distribution across the transmission’s high-stress zones.

Symptoms of Failure

• Intermittent gear slipping under load – When the thrust washer wears thin, axial play increases, causing the clutch packs to lose engagement pressure during acceleration.
• Low oil pressure warnings – A degraded washer alters the oil pump’s internal clearances, triggering erratic pressure readings on the dashboard gauge.
• Metallic debris in transmission fluid – Flaking or scoring of the washer surface introduces fine steel particles into the oil, visible during routine fluid changes.
• Whining or grinding noise from the bell housing – Excessive end float from a worn 0730.100.289 creates a distinct high-pitched sound during gear shifts, especially in reverse.

Technical Specifications

Compatibility

This thrust washer is engineered for the ZF WG200 series transmissions, including the WG180, WG200, and WG210 variants. It is a direct replacement for units manufactured between 1998 and 2018, commonly found in municipal buses, fire trucks, and heavy-duty construction vehicles. The 0730.100.289 also fits select ZF Ecolife models that share the same planetary carrier architecture. Always verify your transmission’s serial number against the OEM parts catalog before installation.
