ZF 0730.000.342 WASHER for WG201 | OEM Genuine Part

Overview

The ZF 0730.000.342 WASHER for WG201 is a precision-engineered sealing component designed to maintain critical clamping force and prevent fluid migration within the transmission assembly. This OEM genuine part sits between the TRANSMISSION HOUSING and mating surfaces, acting as a load-distributing interface that ensures proper torque retention on fasteners. As a factory-specification washer, the SKU 0730.000.342 is essential for maintaining the structural integrity of the WG 200 series gearbox, particularly when paired with the THREADED BUSH and SCREW PLUG in the main housing assembly.

Symptoms of Failure

• Transmission oil seepage at housing joints: A worn or deformed 0730.000.342 washer cannot maintain adequate seal compression, leading to visible oil weeping around the TRANSMISSION HOUSING interface.
• Audible gear rattle under load: Loss of washer thickness reduces clamping force on internal components, allowing axial play that produces metallic noise during acceleration.
• Recurring fastener loosening: When this washer fatigues, bolts and plugs lose preload over time, causing intermittent gear engagement issues and potential fluid contamination.
• Increased operating temperature: Compromised sealing allows hot transmission fluid to escape, reducing lubrication efficiency and causing thermal stress on adjacent parts.

Technical Specifications

Compatibility

This washer is specifically designed for the ZF WG 201 series transmission, but it also fits select models in the WG180, WG200, and WG210 families due to shared housing bolt patterns. It is a direct replacement for the sealing washer used in conjunction with the SCREW PLUG on the transmission sump and side cover. For complete assembly verification, always cross-reference the part with the TRANSMISSION HOUSING casting number to ensure correct fitment.
