ZF 4644.153.221 CLUTCH for WG 180/WG 200 | OEM Genuine Part

Overview

The ZF 4644.153.221 CLUTCH is a critical torque-transfer component engineered for the WG 180 and WG 200 series transmissions. Positioned within the hydraulic clutch pack assembly, this OEM genuine part engages and disengages power flow between the engine and drivetrain, ensuring smooth gear shifts under heavy load conditions. The SKU 4644.153.221 is precision-machined to ZF’s original specifications, guaranteeing direct interchangeability without modification. When paired with the 4460115043: HOUSING, this clutch forms the core of the transmission’s shifting mechanism, delivering reliable performance in construction and agricultural machinery.

Symptoms of Failure

Worn or damaged ZF 4644.153.221 clutches present distinct failure indicators. Operators may notice gear slipping under load, particularly during uphill travel or when towing heavy implements. Another common symptom is delayed or harsh engagement when shifting from neutral to drive, often accompanied by a grinding noise. Oil contamination with metallic debris in the transmission fluid signals clutch plate wear. Finally, erratic shifting patterns or transmission overheating can occur as the clutch loses its ability to maintain proper hydraulic pressure. Addressing these issues promptly prevents damage to the 4469315012: AXLE DRIVE HOUSING and surrounding components.
