Overview
The ZF 4644.130.106 ENGINE CONNECTION is a critical OEM genuine interface component designed specifically for the WG 200 Series transmission family. This precision-engineered part serves as the primary mechanical link between the engine flywheel housing and the transmission bell housing, ensuring correct axial alignment and torque transfer during operation. As a genuine ZF part, SKU 4644.130.106 guarantees factory tolerances and material integrity, preventing misalignment that can lead to premature wear on adjacent driveline components. This connection plate integrates directly with the 4460115043: HOUSING to form a sealed, rigid assembly that withstands high torsional loads.
Symptoms of Failure
When the ZF 4644.130.106 ENGINE CONNECTION begins to degrade, operators often notice specific failure indicators. Oil seepage at the engine-transmission mating surface is a common early sign, as the connection plate loses its sealing capability. Intermittent gear engagement hesitation or a “clunking” noise during acceleration suggests the connection has developed play. Vibration through the chassis at highway speeds typically indicates that the mounting face has warped or cracked. Finally, visible fretting corrosion or metal debris around the bolt holes points to advanced wear requiring immediate replacement.

Compatibility
This ENGINE CONNECTION is engineered for the ZF WG 200 Series transmissions, including models such as WG180, WG200, and WG210. It is also compatible with certain WG 150 variants that share the same bell housing bolt pattern. The part interfaces directly with the 4469315012: AXLE DRIVE HOUSING and requires proper bearing support from the 0750117406: TAPER ROLLER BEARING and 0750117802: TAPERED ROLLER BEARING for optimal rotational stability. Always verify your transmission model and serial number before ordering.
