ZF 0636.015.244 HEXAGON SCREW for WG150/WG180/WG181 | OEM Genuine Part

Overview

The ZF 0636.015.244 HEXAGON SCREW is a critical fastening component engineered for the WG150, WG180, and WG181 transmission series. This OEM genuine part secures the TRANSMISSION HOUSING assembly, ensuring structural integrity under high torque loads. Designed to withstand extreme vibration and thermal cycling, this hexagon screw maintains precise clamping force to prevent component misalignment. The SKU 0636.015.244 is manufactured to ZF’s exacting tolerances, making it a direct replacement for worn or damaged fasteners in heavy-duty industrial transmissions.

Symptoms of Failure

• Transmission oil seepage around housing joints: A loose or fatigued hexagon screw can compromise the seal between the housing and mating surfaces, leading to gradual fluid loss.
• Abnormal gear engagement noise: When this fastener loses torque, internal components shift, causing clunking or grinding sounds during gear changes.
• Vibration at the bell housing: A failing screw allows micro-movement in the assembly, transmitting excessive vibration through the drivetrain during operation.
• Reduced hydraulic pressure: Misalignment from a degraded screw can disrupt oil flow paths, resulting in sluggish shifting or clutch slippage.

Technical Specifications

Compatibility

This hexagon screw is designed for ZF WG series transmissions, specifically the WG150, WG180, WG181, and WG65 models. It is commonly used in conjunction with the HEXAGON SCREW (0636011038) for housing cover retention and the HEXAGON SCREW (0636011118) for valve body mounting. For complete assembly, pair it with the HEXAGON SCREW (0636016015) used in the oil pan attachment. Always verify thread pitch and length against your transmission’s service manual before installation.
