Overview
The ZF 0730.008.815 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. Positioned within the gear train assembly, the SKU 0730.008.815 prevents galling and maintains axial alignment under high-torque conditions. As a factory-specified part, it guarantees exact dimensional tolerances required for reliable WG200 operation.
Symptoms of Failure
- Transmission oil seepage at bolt interfaces: A worn or deformed 0730.008.815 washer can compromise sealing pressure, leading to slow fluid migration around fasteners.
- Gear engagement hesitation during load shifts: When this washer loses its flatness, fastener preload diminishes, causing slight axial movement that delays clutch pack engagement.
- Abnormal metallic debris in transmission fluid: Degraded washers shed fine steel particles that contaminate the hydraulic circuit, often mistaken for bearing wear.
- Recurring fastener loosening in high-vibration applications: A collapsed washer reduces clamping force, allowing hexagon screws to back out over time.
