ZF 0730.109.597 WASHER | OEM Genuine Part

Overview

The ZF 0730.109.597 WASHER is a precision-engineered OEM genuine component designed for heavy-duty construction machinery transmissions. This hardened steel washer functions as a critical load-spreading interface within the planetary gearset and main shaft assembly, ensuring proper axial clearance and preventing metal-on-metal contact between rotating elements. As an authentic ZF part, SKU 0730.109.597 guarantees exact dimensional tolerances required for reliable torque transmission in demanding off-highway applications. This washer is frequently replaced during transmission overhauls alongside the 2094104412: MAIN SHAFT and 2094304054: MAIN SHAFT to restore factory-specified end-play.

Symptoms of Failure

• Transmission oil leaks at shaft seals – A worn 0730.109.597 washer allows excessive axial movement, distorting seal lips and causing fluid seepage around the output flange.
• Gear slipping under load – When this washer loses its original thickness, gear engagement depth decreases, leading to intermittent slipping during excavation or grading operations.
• Metallic grinding noises from the transmission housing – Thinned washers permit gear teeth to contact housing walls, producing a distinct scraping sound during low-speed operation.
• Vibration in the driveline during shifting – Uneven washer wear creates imbalance in the main shaft assembly, transmitting noticeable shudder through the chassis when changing gears.

Technical Specifications

Compatibility

This washer is engineered for ZF WG-series powershift transmissions commonly used in construction machinery. It is a direct fit for the following models: WG180, WG200, WG210, and WG250. The 0730.109.597 washer is installed on the main shaft between the gearshift mechanism and the planetary carrier. For complete transmission rebuilds, pair this washer with the 2094106010: SHIFT SYSTEM and 2094206001: GEARSHIFT SHAFT to ensure synchronized engagement of all clutch packs.
