Overview
The ZF 4644.152.468 CLUTCH is a critical torque-transfer component engineered specifically for the WG 180 and WG 200 series transmissions. This OEM genuine part sits within the planetary gear set assembly, where it engages and disengages power flow between the input shaft and the main drive gears. The SKU 4644.152.468 is manufactured to ZF’s original tolerances, ensuring precise hydraulic actuation and consistent clamping force under high-load industrial applications. When installed alongside a 4644101216 TRANSMISSION HOUSING or a 4644301223 TRANSMISSION HOUSING, this clutch maintains the structural integrity required for heavy-duty operations.
Symptoms of Failure
When the ZF 4644.152.468 clutch begins to wear, operators often notice delayed engagement or gear slipping under load, particularly during uphill travel or when towing. A second common symptom is erratic shift quality, where the transmission hunts between gears or produces harsh engagement noises. Third, low hydraulic pressure warnings may appear on the dashboard, as worn clutch plates allow fluid bypass. Finally, visible metal particles in the transmission fluid indicate friction material degradation from this specific clutch pack. Ignoring these signs can lead to catastrophic transmission failure, requiring replacement of the entire assembly.
