ZF 4644.151.531 COUPLING for WG 180/WG 200 | OEM Genuine Part

Overview

The ZF 4644.151.531 COUPLING is a precision-engineered component designed for the WG 180 and WG 200 transmission series. This OEM genuine part serves as the critical torque transfer link between the engine flywheel and the transmission input shaft, ensuring smooth power delivery and vibration dampening in heavy-duty industrial applications. The SKU 4644.151.531 sits directly within the bell housing assembly, connecting directly to the TRANSMISSION HOUSING (4644101160) and the TRANSMISSION HOUSING (4644301323) to maintain structural integrity during high-torque operations.

Symptoms of Failure

When the 4644.151.531 coupling begins to wear, operators may notice these specific failure indicators:

• Transmission gear slipping under load – A worn coupling cannot maintain proper engagement, causing intermittent power loss during acceleration or uphill operation.
• Oil leaks near the bell housing – Degraded seals around the coupling allow transmission fluid to escape, often visible as drips from the joint between the engine and transmission.
• Abnormal vibration or shuddering – Excessive play in the coupling creates driveline oscillations, particularly noticeable at low RPM or during gear changes.
• Metallic grinding noises – Worn splines or bushing surfaces produce a distinct grinding sound when the transmission is engaged.

Technical Specifications

Compatibility

This ZF 4644.151.531 COUPLING is specifically engineered for the following ZF transmission models:

• ZF WG 180 (all variants)
• ZF WG 200 (all variants)
• ZF WG 201 Series (current category)

For proper installation, this coupling works in conjunction with the THREADED BUSH (4644301189) and the SCREW PLUG (4475280043) to secure the assembly. Always verify housing compatibility with your specific transmission serial number before ordering.
