Overview
The ZF 0636.010.052 HEXAGON SCREW is a critical fastening component engineered specifically for the WG 65 series transmission. This OEM genuine part secures the 4616105413: OUTPUT assembly to the 4616101117: TRANSMISSION HOUSING, ensuring precise clamping force and vibration resistance under high-torque conditions. Designed to withstand extreme thermal cycling and mechanical stress, this hexagon screw (SKU 0636.010.052) prevents loosening in heavy-duty industrial applications. It is a direct replacement for the original factory-installed fastener, maintaining the structural integrity of the drivetrain.
Symptoms of Failure
When the ZF 0636.010.052 hexagon screw degrades or fatigues, operators may notice specific warning signs. Oil seepage around the output flange interface often indicates insufficient clamping pressure, allowing transmission fluid to escape past the seal. Abnormal gear engagement noise or slipping can occur if the screw loosens, causing misalignment between the 4616203017: OUTPUT FLANGE and the housing. Visible thread galling or corrosion on the screw shank compromises torque retention, leading to progressive joint failure. Increased driveline vibration at low RPM suggests the fastener has lost its preload, permitting micro-movement of the output assembly.

Compatibility
This hexagon screw is primarily designed for the ZF WG 65 series transmission, but it also fits select models in the WG180 and WG200 families due to shared output housing geometries. It is commonly used in WG65, WG180, and WG200 transmissions found in off-highway vehicles, agricultural machinery, and industrial power take-off units. Always verify thread pitch and length against your specific transmission variant before installation. The screw works in conjunction with the 0636011038: HEXAGON SCREW for adjacent mounting points on the same flange.
