ZF 0636.011.614 HEXAGON SCREW for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 0636.011.614 HEXAGON SCREW is a critical fastening element engineered for secure assembly within the WG100, WG130, and WG131 transmission series. This OEM genuine part ensures precise clamping force when mounting key structural components, including the 2094101012 TRANSMISSION HOUSING and the 2094301036 HOUSING. Designed to withstand high torque and vibration, this hexagon screw maintains the integrity of the transmission’s internal architecture. The SKU 0636.011.614 is directly interchangeable with factory-installed hardware, guaranteeing a perfect fit for maintenance or rebuild operations.

Symptoms of Failure

• Transmission oil seepage at housing joints: A loose or fatigued hexagon screw can compromise the seal between the 2094298057 HOUSING and the 2094301071 COVER, leading to visible fluid leaks around mating surfaces.
• Abnormal gear engagement noise: When this fastener loses its clamping tension, internal components may shift, causing a distinct clattering or grinding sound during gear changes.
• Vibration during torque converter lockup: A degraded hexagon screw can allow micro-movement in the housing assembly, resulting in noticeable driveline shudder under load.
• Intermittent gear slipping under heavy load: Insufficient fastener torque can alter the alignment of clutch packs and valve bodies, leading to erratic power transfer.

Technical Specifications

Compatibility

This hexagon screw is specifically designed for ZF WG-series transmissions, including the WG100, WG130, and WG131 models. It is also commonly used in the WG180 and WG200 series for securing housing assemblies and covers. Always verify the thread pitch and length against your transmission’s service manual before installation. For related sealing components, consider the 0750111371 SHAFT SEAL and the 0634303085 O-RING to ensure a complete leak-free assembly.
