ZF 0636.010.284 HEXAGON SCREW for WG150 | OEM Genuine Part

Overview

The ZF 0636.010.284 HEXAGON SCREW is a critical OEM genuine fastening component engineered specifically for the WG150 transmission series. This precision-machined bolt secures the transmission housing assembly, ensuring structural integrity under high-torque loads. As a factory-specified part, the SKU 0636.010.284 is designed to withstand extreme vibration and thermal cycling within the gearbox. It is typically installed at the interface between the main casing and the TRANSMISSION HOUSING or the TRANSMISSION HOUSING, providing a leak-proof seal and preventing axial movement of internal components.

Symptoms of Failure

• Transmission oil leaks at the housing seam: A worn or stripped hexagon screw cannot maintain clamping force, allowing ATF fluid to seep past the gasket. This is a common symptom when the 0636.010.284 loses its thread engagement.
• Abnormal gearbox vibration or rattle: Loose fasteners cause micro-movement between the transmission housing sections, leading to audible noise during acceleration or deceleration.
• Difficulty shifting or gear slippage: If the screw fails completely, internal misalignment can occur, affecting shift timing and clutch engagement. This often mimics hydraulic system failures.
• Visible corrosion or thread galling: Exposure to heat and moisture can degrade the hexagon screw, making removal difficult and compromising the seal integrity.

Technical Specifications

Compatibility

While the 0636.010.284 HEXAGON SCREW is primarily designed for the WG150 transmission, it is also compatible with other ZF WG-series models that share the same housing architecture. This includes the WG180, WG200, and WG210 series. The screw is used in conjunction with the TYPE PLATE for identification and the GROOVED STUD for alignment. Always verify thread pitch and length against your specific transmission model before installation.
