ZF 0730.109.594 WASHER | OEM Genuine Part

Overview

The ZF 0730.109.594 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, specifically positioned between the main shaft and shift system components. The SKU 0730.109.594 ensures correct load distribution and maintains proper gear mesh alignment under extreme torque conditions. When installed alongside the 2094104412: MAIN SHAFT and 2094106010: SHIFT SYSTEM, this washer prevents metal-on-metal contact that would otherwise accelerate wear on adjacent rotating assemblies.

Symptoms of Failure

• Transmission oil leaks from the shift housing area: A worn 0730.109.594 washer allows axial play, breaking the seal between the 2094206001: GEARSHIFT SHAFT and the housing, causing fluid seepage during operation.
• Intermittent gear slipping under load: When this thrust washer loses its precise thickness, the 2094304054: MAIN SHAFT shifts out of tolerance, resulting in partial clutch pack engagement and power loss.
• Metallic grinding noise during gear changes: Excessive clearance from a collapsed washer allows the shift system components to contact the transmission case, producing a distinct high-pitched grinding sound.
• Vibration in the driveline at low speeds: Uneven washer wear creates axial runout that transmits through the main shaft, felt as rhythmic shaking during forward or reverse operation.

Technical Specifications

Compatibility

This genuine ZF washer is engineered for the WG180, WG200, and WG210 series powershift transmissions commonly found in wheel loaders, excavators, and telehandlers. It is a direct replacement for the thrust washer position on the main shaft assembly in these models. The 0730.109.594 also fits select ZF 4WG-200 and 6WG-200 variants used in construction machinery from 1998 onward. Always verify your transmission serial number against the ZF parts catalog before ordering.

“acceptedAnswer”: {
“@type”: “Answer”,
“text”: “No. The 0730.109.594 washer is a single-use component that deforms slightly during initial torque application. Always install a new OEM washer when replacing the main shaft or shift system to ensure proper axial clearance and prevent premature transmission failure.”
