ZF 0730.006.509 WASHER for WG65 | OEM Genuine Part

Overview

The ZF 0730.006.509 WASHER is a precision-engineered OEM genuine component designed specifically for the WG 65 series transmission. This hardened steel washer functions as a critical load-spreading interface between fasteners and transmission housing surfaces, ensuring proper clamp load distribution during assembly. Installed within the gear train assembly, the SKU 0730.006.509 prevents galling and maintains alignment between mating components. It is typically secured using a 0636011118 HEXAGON SCREW and interfaces directly with the 4616101111 TRANSMISSION HOUSING to maintain structural integrity under high torque conditions.

Symptoms of Failure

• Oil seepage at housing joints: A worn or deformed 0730.006.509 washer can cause uneven clamping, leading to transmission fluid leaks around the 4616301304 HOUSING interface.
• Gear engagement hesitation: Loss of washer thickness alters bearing preload, resulting in delayed or rough shifting during load cycles.
• Fastener loosening under vibration: A crushed or fatigued washer reduces bolt retention, causing audible rattling or component misalignment.
• Metallic debris in oil pan: Spalling of the washer surface introduces ferrous particles into the lubrication system, accelerating wear on adjacent gears.

Technical Specifications

Compatibility

This washer is engineered for the ZF WG 65 series, but its dimensions and load rating also suit other ZF powershift transmissions including WG180, WG200, and WG210 models. It is commonly replaced during overhaul of the 4616301309 HOUSING assembly. Always verify fitment against your transmission’s parts catalog before ordering.
