ZF 0737.006.084 HEXAGON NUT for WG200 | OEM Genuine Part

Overview

The ZF 0737.006.084 HEXAGON NUT is a critical fastening component engineered specifically for the WG200 series transmission. This OEM genuine part secures the main shaft assembly and ensures precise axial clamping force within the gear train. Located in the upper valve body and clutch housing interface, the SKU 0737.006.084 prevents rotational play that can lead to misalignment of adjacent components. When paired with the 0636011429 HEXAGON SCREW and the 0730100365 WASHER, this nut forms a complete locking system that maintains structural integrity under high torque loads.

Symptoms of Failure

• Transmission oil seepage at the output flange: A loose or worn 0737.006.084 nut allows the shaft seal to shift, causing gradual ATF leaks around the rear housing.
• Intermittent gear slipping under load: When the hexagon nut loses its torque retention, the clutch pack clearance increases, resulting in delayed engagement or slipping during acceleration.
• Abnormal vibration during shifting: A compromised nut permits axial shaft movement, producing a distinct shudder or clunk sound when the transmission transitions between gears.
• Difficulty engaging reverse gear: Insufficient clamping from a degraded nut can cause the reverse clutch drum to float, leading to hard or incomplete reverse engagement.

Technical Specifications

Compatibility

This hexagon nut is a direct fit for the ZF WG180, WG200, and WG210 series transmissions used in medium-duty commercial vehicles and off-highway equipment. It also applies to the ZF 6WG200 and 8WG200 variants. The 0737.006.084 is commonly installed alongside the 4460165051 CONSOLE and the 4460368311 CONSOLE, which support the shift mechanism housing. Always verify thread pitch and hex size against your specific transmission model before installation.
