ZF 0730.108.426 WASHER | OEM Genuine Part

Overview

The ZF 0730.108.426 WASHER is an OEM genuine precision shim engineered for critical load distribution within heavy-duty construction machinery transmissions. This hardened steel washer sits between rotating assemblies and housing surfaces, preventing axial play and maintaining precise gear alignment. As part number 0730.108.426, it functions as a thrust washer in the planetary gearset area, directly supporting the 2094104412: MAIN SHAFT and the 2094304054: MAIN SHAFT during high-torque operations. Without this washer, the entire 2094106010: SHIFT SYSTEM can experience misalignment, leading to premature wear on adjacent components.

Symptoms of Failure

• Transmission oil leaks around the output flange: A worn 0730.108.426 washer allows the 2094206001: GEARSHIFT SHAFT to shift laterally, breaking the seal between the housing and shaft.
• Gear slipping under load in construction equipment: When this washer loses its thickness tolerance, the main shaft stack height decreases, causing clutch packs to engage incompletely.
• Metallic grinding noise during gear changes: Excessive clearance from a flattened washer allows gear teeth to contact housing walls, producing a distinct scraping sound.
• Vibration in the driveline at low speeds: A deformed washer cannot dampen axial thrust from the 2094304054: MAIN SHAFT, transmitting vibration through the shift fork assembly.

Technical Specifications

Compatibility

This washer is specifically engineered for ZF WG180, WG200, and WG211 series powershift transmissions commonly found in wheel loaders, graders, and dump trucks. It also fits select ZF Ecomat 4HP and 5HP models used in construction machinery. Always verify the part number 0730.108.426 against your transmission’s parts manual before installation.
