Overview
The ZF 0636.015.347 HEXAGON SCREW is a critical fastening element engineered for the WG100, WG130, and WG131 transmission series. This OEM genuine part secures the 4699101152: HOUSING assembly, ensuring precise clamping force to maintain gear alignment and torque transfer integrity. As a hexagon-headed bolt, it resists vibrational loosening in high-stress environments. The SKU 0636.015.347 is your direct reference for authentic ZF replacement, guaranteeing thread pitch and tensile strength match factory specifications.
Symptoms of Failure
- Oil seepage around housing joints: A loosened or fatigued hexagon screw compromises the seal between the 4699309059: HOUSING COVER and main casing, leading to visible fluid trails.
- Gear engagement hesitation: When this fastener loses preload, the housing shifts slightly, causing delayed or rough shifting under load.
- Metallic rattling from bell housing: Excessive clearance from a stripped or broken screw allows the 0636101411: CAP SCREW assembly to vibrate against adjacent components.
- Torque converter misalignment: A failed hexagon screw can induce axial play, resulting in uneven wear on the 0631302212: CYLINDRICAL PIN alignment system.

Compatibility
This hexagon screw is specifically validated for ZF WG100, WG130, and WG131 transmissions. It also serves as a direct replacement in WG180 and WG200 series where the housing interface uses identical thread patterns. Always verify the 0636302013: SCREW PLUG and 0750108986: SCREW PLUG positions are clear before installation to avoid cross-threading.
