ZF 0636.102.037 CAP SCREW for WG210 | OEM Genuine Part

Overview

The ZF 0636.102.037 CAP SCREW is a critical fastening component engineered specifically for the WG210 transmission series. This OEM genuine part secures the transmission housing assembly, ensuring precise clamping force and structural integrity under high-torque conditions. Positioned along the main casing joints, this cap screw works in concert with the 4657101042: TRANSMISSION HOUSING and the 4657201028: HOUS.FRONT SECT to maintain leak-free sealing and prevent gear train misalignment. The SKU 0636.102.037 is manufactured to ZF’s exacting tolerances, making it a direct replacement for worn or damaged fasteners in WG210 gearboxes.

Symptoms of Failure

• Transmission fluid seepage around bolt heads: When the cap screw loses its preload, oil can migrate past the mating surfaces of the 4657201013: HOUSING REAR PART, leading to visible drips or wet spots on the casing exterior.
• Abnormal gear rattle or vibration: A loosened 0636.102.037 allows micro-movement between housing sections, causing gear teeth to contact unevenly and generating low-frequency noise during acceleration.
• Intermittent clutch engagement hesitation: Loss of housing rigidity can shift the alignment of valve body passages, delaying hydraulic pressure delivery to clutch packs.
• Increased metallic debris in oil pan: Fretting corrosion from a loose cap screw introduces fine steel particles into the lubrication circuit, accelerating wear on bearings and the 0631306792: CYLINDRICAL PIN.

Technical Specifications

Compatibility

This cap screw is primarily designed for the WG210 transmission series, but its thread pattern and length also suit the WG180, WG200, and WG250 models where identical housing bolt patterns are used. It is a direct fit for any ZF gearbox employing the 0636.102.XXX fastener family. Always verify the thread engagement depth against your specific housing variant before installation.
