ZF 0730.101.098 WASHER for WG200 | OEM Genuine Part

Overview

The ZF 0730.101.098 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 element between fastening hardware and transmission housing surfaces, ensuring proper clamp load distribution during assembly. Installed within the planetary gearset or clutch pack retention system, the SKU 0730.101.098 prevents galling and maintains axial clearance tolerances. When replacing this washer, always inspect the mating 4460165051 CONSOLE and the 4460368311 CONSOLE for wear patterns that could indicate uneven loading.

Symptoms of Failure

• Transmission oil seepage at housing joints — A collapsed or deformed 0730.101.098 washer reduces clamping force, allowing ATF to escape past gaskets and seals, often visible as wet streaks near the bell housing.
• Intermittent gear engagement hesitation — When the washer fatigues, axial play increases in the clutch pack, causing delayed or harsh shifting under load, particularly in WG200-equipped vehicles.
• Metallic debris in transmission fluid — A fractured washer sheds fine steel particles that contaminate the oil, detectable during routine fluid changes or filter inspections.
• Abnormal driveline vibration — Loss of washer thickness alters the preload on the input shaft bearing, producing low-frequency rumble during acceleration.

Technical Specifications

Compatibility

This washer is primarily designed for the ZF WG 200 series transmissions, including models WG180, WG200, and WG210. It is also commonly used in the ZF 6HP and 8HP automatic transmissions for torque converter mounting points. Always verify fitment with your specific transmission serial number. For related assembly components, consider the 0636011429 HEXAGON SCREW which secures this washer in place, and the 0730100365 WASHER used in adjacent clutch pack stacks.
