ZF 4644.152.126 COUPLING for WG 180/WG 200 | OEM Genuine Part

Genuine ZF COUPLING (Part No. 4644.152.126). This part fits: 3 WG 200, 3 WG 201, 6 WG 200(555), 6 WG 200(555/4), 6 WG 200(555/5) and 1 more models. Found in: Coupling. Also referenced as: 4644152126 / 4644.152.126 / 4644 152 126.

Overview

The ZF 4644.152.126 COUPLING is a critical driveline component engineered specifically for the WG 180 and WG 200 series transmissions. This OEM genuine part serves as the primary mechanical link between the engine output and the transmission input shaft, ensuring precise torque transfer and torsional vibration dampening. Located within the bell housing assembly, the 4644.152.126 coupling interfaces directly with the 4644105423: DISCONNECTION mechanism and the 4644303054: OUTPUT FLANGE to maintain driveline integrity. As a genuine ZF component, SKU 4644.152.126 guarantees factory-specified tolerances for heavy-duty industrial applications.

Symptoms of Failure

  • Transmission oil leaks at bell housing: Worn coupling seals allow hydraulic fluid to escape, often pooling near the 4644101229: TRANSMISSION HOUSING joint.
  • Vibration during gear engagement: Deteriorated elastomeric elements in the coupling cause excessive driveline shudder under load.
  • Metallic clicking from transmission front: Loose or fatigued coupling splines produce audible noise during acceleration or deceleration.
  • Erratic shift timing: Failed coupling dampening disrupts torque converter lockup, triggering harsh shifts in WG 200 series units.
