ZF 0730.107.707 WASHER | OEM Genuine Part

Overview

The ZF 0730.107.707 WASHER is an OEM genuine thrust washer engineered for precise axial load management within heavy-duty construction machinery transmissions. This component sits directly between rotating gear assemblies and the transmission housing, acting as a sacrificial bearing surface that maintains critical clearances. Specifically designed for ZF power shift transmissions, the SKU 0730.107.707 ensures that gear stacks remain properly spaced under high-torque conditions, preventing metal-on-metal contact that would otherwise cause catastrophic wear. When installed alongside the 2094104412: MAIN SHAFT and the 2094304054: MAIN SHAFT, this washer forms a foundational component of the transmission’s load-bearing architecture.

Symptoms of Failure

• Transmission oil leaks around the main shaft housing: A worn 0730.107.707 washer loses its sealing surface, allowing pressurized ATF to seep past the shaft seals. This manifests as visible drips under the bell housing after machine shutdown.
• Gear slipping under load during excavation: When the washer thickness degrades below specification, axial play increases, causing the 2094106010: SHIFT SYSTEM to lose engagement pressure. Operators report intermittent power loss when digging into hard-packed material.
• Metallic grinding noise during gear changes: Excessive clearance from a collapsed washer allows the 2094206001: GEARSHIFT SHAFT to contact the housing, producing a distinct high-pitched scraping sound that worsens with transmission temperature rise.
• Increased end-play on the main shaft: Measurable axial movement exceeding 0.5mm at the input flange indicates the washer has been compressed beyond its elastic limit, requiring immediate replacement to prevent secondary damage to adjacent bearings.

Technical Specifications

Compatibility

This washer is a standard fitment across ZF’s WG-series powershift transmissions commonly found in wheel loaders, dozers, and telehandlers. Verified compatible models include the WG180, WG200, WG210, and WG250 series. It also applies to select variants of the Ergopower and Ecomat transmissions used in agricultural tractors. For precise fitment confirmation, cross-reference your transmission serial number against the ZF parts catalog. The washer interfaces directly with the 2094306019: WASHER in the clutch pack stack and is retained by the 0630513070: SNAP RING on the output shaft.
