Overview
The ZF 0736.101.206 CAP SCREW is a critical fastening component engineered specifically for the WG 100 series transmission assembly. This OEM genuine part secures the shift mechanism housing and maintains precise clamping force within the gear train. The SKU 0736.101.206 ensures a factory-spec fitment, preventing axial movement that could compromise gear alignment. When installed alongside the 2094104412: MAIN SHAFT and the 2094304054: MAIN SHAFT, this cap screw delivers the structural integrity required for heavy-duty industrial applications.
Symptoms of Failure
- Transmission oil seepage at housing joints: A worn or stripped cap screw reduces sealing pressure, leading to fluid migration around the WG100 casing. This is a common “ZF transmission oil leak” indicator.
- Gear engagement hesitation or grinding: When the cap screw loosens, the 2094106010: SHIFT SYSTEM can shift out of tolerance, causing delayed or rough gear changes.
- Abnormal driveline vibration: Insufficient clamping from a failing 0736.101.206 allows the 2094206001: GEARSHIFT SHAFT to develop play, transmitting vibration through the chassis during operation.
- Metallic debris in transmission fluid: A fractured cap screw can shed particles into the oil circuit, accelerating wear on bearings and synchronizers.

Compatibility
This cap screw is primarily designed for the ZF WG100 series transmission. Based on its thread pattern and application, it is also compatible with the WG180 and WG200 models where the shift housing uses identical bolt patterns. Always verify fitment against your specific transmission serial number. For complete rebuilds, pair this part with the 2094306053: GEARSHIFT SHAFT and the 0630513070: SNAP RING for optimal assembly integrity.

Frequently Asked Questions
Q: Can the ZF 0736.101.206 cap screw be reused after removal?
A: ZF recommends replacing this cap screw with a new OEM unit during any transmission overhaul. The thread locking compound and torque-to-yield design make reuse unreliable for maintaining proper clamp force.
Q: What torque specification is required for this cap screw?
A: For the WG100 series, the standard tightening torque is 45 Nm plus an additional 90-degree angle turn. Always consult your service manual for exact values, as variations exist between transmission generations.
Q: Will this part fit the ZF WG180 transmission?
A: Yes, the 0736.101.206 cap screw is dimensionally identical to the fasteners used in WG180 shift housings. However, verify that your WG180 uses the M10 x 1.5 thread pattern before installation.
