ZF 0730.107.719 WASHER | OEM Genuine Part

Overview

The ZF 0730.107.719 WASHER is a precision-engineered OEM genuine component designed for heavy-duty construction machinery transmissions. This hardened steel washer functions as a critical thrust bearing surface and axial spacer within the planetary gearset assembly, ensuring correct load distribution and shaft alignment during high-torque operations. The SKU 0730.107.719 is specifically positioned between the main shaft and gearshift shaft components, preventing metal-on-metal contact that would otherwise lead to premature wear. As a factory-specification part, it maintains the exact clearance tolerances required for ZF’s modular transmission architecture.

Symptoms of Failure

• Transmission oil leaks near the main shaft housing – When the 0730.107.719 washer wears thin, seal compression changes, allowing hydraulic fluid to escape past the shaft bore.
• Gear slipping under load in construction equipment – A collapsed washer reduces preload on the 2094104412: MAIN SHAFT, causing intermittent disengagement of clutch packs during excavation or grading operations.
• Metallic grinding noise during gear changes – Worn washer material contaminates the transmission fluid, accelerating damage to the 2094106010: SHIFT SYSTEM components.
• Excessive axial play in the driveline – Measurable end-float at the output flange indicates the washer has lost its original thickness, requiring immediate replacement to avoid catastrophic failure.

Technical Specifications

Compatibility

This washer is engineered for ZF WG-series powershift transmissions commonly found in wheel loaders, dozers, and telehandlers. Confirmed compatible models include WG180, WG200, WG210, and WG310 series. It also applies to select ZF 4WG-200 and 6WG-310 variants used in construction machinery from 2005 onward. Always verify fitment with the 2094304054: MAIN SHAFT and 2094206001: GEARSHIFT SHAFT assemblies, as these components share the same axial stack-up tolerances.
