Overview
The ZF 4644.152.452 CLUTCH is a critical torque-transfer component engineered for the WG 180 and WG 200 series transmissions. Positioned within the planetary gear set assembly, this OEM genuine part directly manages the engagement and disengagement of power flow between the engine and the drivetrain. The SKU 4644.152.452 is precision-machined to ZF’s original specifications, ensuring seamless integration with the 4644101160: TRANSMISSION HOUSING and the 4644301323: TRANSMISSION HOUSING to maintain structural integrity under heavy loads.
Symptoms of Failure
When the ZF 4644.152.452 clutch begins to degrade, operators may notice specific performance issues. Common failure symptoms include:
- Oil leaks near the clutch housing – Worn seals allow hydraulic fluid to escape, reducing system pressure.
- Gear slipping under load – The clutch fails to hold torque, causing unexpected disengagement during acceleration.
- Delayed or harsh shifting – Inconsistent clutch engagement leads to jerky gear changes or hesitation.
- Burning smell from transmission fluid – Excessive friction from a slipping clutch overheats the oil.
