ZF 0730.109.704 WASHER for WG200 | OEM Genuine Part

Overview

The ZF 0730.109.704 WASHER is a precision-engineered OEM genuine component designed specifically for the WG200 series transmission. This hardened steel washer functions as a critical load-spreading interface between fasteners and transmission housing surfaces, ensuring proper clamping force distribution during assembly. Located within the main gear train assembly, the SKU 0730.109.704 prevents galling and maintains axial alignment under high-torque conditions. When installed alongside the 4644105424 DISCONNECTION and 4644303538 OUTPUT FLANGE, this washer guarantees secure retention of the 0636021036 HEXAGON SCREW within the 4644101224 TRANSMISSION HOUSING.

Symptoms of Failure

• Transmission oil seepage at fastener points: A worn or crushed washer loses its sealing integrity, allowing ATF to migrate past bolt heads. This often appears as wet spots around the housing perimeter.
• Audible rattling or loose fasteners: When the washer deforms beyond tolerance, the hexagon screw can back out under vibration, producing metallic chatter during gear engagement.
• Inconsistent gear engagement under load: Failed washers permit micro-movement of the output flange, causing delayed or harsh shifting in the WG200 series.
• Visible deformation or cracking: Inspecting the washer during routine service reveals edge cracking or permanent set, indicating imminent failure.
