ZF 0730.008.810 WASHER for WG200 | OEM Genuine Part

Overview

The ZF 0730.008.810 WASHER is a precision-engineered OEM genuine component designed specifically for the WG 200 series transmission. This hardened steel washer functions as a critical load-spreading interface between fasteners and transmission housing surfaces, ensuring proper torque retention and sealing integrity. Positioned within the planetary gear assembly and clutch pack areas, the SKU 0730.008.810 prevents metal-on-metal contact that could lead to component fretting or misalignment. Its exacting dimensional tolerances are essential for maintaining the axial clearances required for smooth gear engagement and hydraulic pressure regulation in heavy-duty ZF off-highway transmissions.

Symptoms of Failure

• Transmission oil seepage at bolt interfaces: A worn or crushed 0730.008.810 washer can no longer maintain a proper seal, leading to slow oil weeping around fasteners, often mistaken for gasket failure.
• Gear engagement hesitation or slipping: When this washer deforms under load, axial play increases in the clutch pack, causing delayed shifts or momentary power loss during acceleration.
• Abnormal metallic rattling from bell housing: A collapsed washer allows fastener loosening, resulting in a distinct rattle at idle that intensifies under load as components shift out of alignment.
• Torque loss on critical fasteners: Repeated thermal cycling can cause the washer to lose its spring memory, leading to bolts backing off and requiring frequent retorquing during maintenance intervals.

Technical Specifications

Compatibility

This washer is primarily designed for the ZF WG 200 series transmission, including models WG200, WG180, and WG210. It is also used in select ZF Ergopower and Ecolife variants that share the same planetary carrier bolt pattern. The 0730.008.810 is commonly found in torque converter housing assemblies and clutch drum retention points. For applications requiring a thinner profile, consider the 0730100365: WASHER which serves a similar function in adjacent valve body sections.

When servicing the WG200, always inspect the 4460165051: CONSOLE and 4460368311: CONSOLE for wear, as these consoles support the washer seating surface. Secure the assembly using 0636011429: HEXAGON SCREW to ensure proper clamping force. For complete rebuilds, verify the condition of the 4644105418: DISCONNECTION and 4644305041: ADAPTER which interface directly with the washer’s load path.
