ZF 0730.008.855 WASHER for WG200 | OEM Genuine Part

Overview

The ZF 0730.008.855 WASHER is a precision-engineered OEM genuine component designed for the WG200 series transmissions. This hardened steel washer functions as a critical load-spreading interface between fasteners and transmission housing surfaces, ensuring proper torque retention and preventing galling during high-vibration operations. Located within the clutch pack or planetary gear assembly, this washer (SKU: 0730.008.855) maintains axial clearance and reduces fretting wear on adjacent components. For complete assembly integrity, this washer is often paired with the 0636011429 HEXAGON SCREW and the 0730100365 WASHER to achieve optimal clamping force distribution.

Symptoms of Failure

• Transmission oil seepage at bolt interfaces: A worn or deformed 0730.008.855 washer allows fastener loosening, creating micro-gaps that permit ATF leakage under pressure.
• Intermittent gear slipping under load: When the washer loses its original thickness, axial play increases in the planetary set, causing momentary torque loss during acceleration.
• Metallic debris in the oil pan: Fretting corrosion from a failed washer generates fine steel particles that contaminate the hydraulic circuit and clog valve bodies.
• Abnormal driveline vibration: Uneven washer compression leads to misalignment of the 4460165051 CONSOLE and 4460368311 CONSOLE, producing low-frequency shudder during gear changes.

Technical Specifications

Compatibility

This OEM washer is engineered for the ZF WG200 series transmissions, including the WG180, WG200, and WG210 variants. It is also compatible with select ZF Ecolife and AS Tronic mid-range models that share the same planetary carrier bolt pattern. Always verify fitment with your transmission’s parts catalog, as the 0730.008.855 is frequently used alongside the 4644105418 DISCONNECTION and 4644305041 ADAPTER in clutch housing assemblies.
