ZF 4644.130.158 ENGINE CONNECTION for WG201 | OEM Genuine Part

Overview

The ZF 4644.130.158 ENGINE CONNECTION is a critical interface component designed for the WG 201 Series transmission family. This OEM genuine part serves as the mechanical link between the transmission housing and the engine bellhousing, ensuring precise alignment and secure torque transfer during operation. Positioned at the front of the gearbox assembly, the ENGINE CONNECTION absorbs vibrational loads while maintaining a sealed boundary against contaminants. The SKU 4644.130.158 is manufactured to ZF’s exacting tolerances, making it essential for rebuilds or replacements in heavy-duty industrial drivelines.

Symptoms of Failure

• Oil seepage at the engine-transmission interface: A worn ENGINE CONNECTION can cause gradual fluid loss, often noticed as dark streaks on the bellhousing exterior.
• Gear engagement hesitation or slipping: Misalignment from a degraded connection point leads to delayed clutch pack engagement under load.
• Abnormal driveline vibration: When the part loses its structural integrity, operators may feel rhythmic shaking during acceleration or deceleration.
• Metallic rattling from the front of the transmission: Loose fitment allows the housing to shift slightly, creating audible contact between adjacent components.

Technical Specifications

Compatibility

This ENGINE CONNECTION is engineered for the ZF WG 201 Series, but it also fits select models in the WG180, WG200, and WG210 families where the bellhousing interface matches the 120 mm bolt pattern. It is commonly used in off-highway trucks, wheel loaders, and industrial pumps. For proper installation, always pair this part with a new SEALING RING (0634801088) and verify the TRANSMISSION HOUSING (4644101241) or TRANSMISSION HOUSING (4644301365) is free of cracks. Secure the assembly using a SCREW PLUG (0636305019) to prevent fluid bypass.
