Overview
The ZF 4642.152.471 CLUTCH is a critical torque-transfer component engineered specifically for the WG 150 Series transmission. This OEM genuine part serves as the primary engagement mechanism, managing power flow between the engine and the gear train. Positioned within the hydraulic control circuit, the clutch assembly ensures smooth gear shifts and reliable load handling under heavy-duty industrial conditions. The SKU 4642.152.471 is manufactured to ZF’s exacting tolerances, guaranteeing a direct fit and long service life. When paired with a robust TRANSMISSION HOUSING (4642101109) or a TRANSMISSION HOUSING (4642301205), this clutch delivers consistent performance in demanding environments.
Symptoms of Failure
When the ZF 4642.152.471 CLUTCH begins to wear, operators often notice specific operational issues. Delayed or harsh gear engagement is a primary symptom, where the transmission hesitates before shifting or clunks into gear. Another common failure sign is slipping under load, where engine RPM rises without a corresponding increase in vehicle speed, particularly during uphill climbs. Oil leaks near the clutch housing may also develop, indicating seal degradation. Finally, intermittent loss of drive in specific gears can occur, often accompanied by burnt transmission fluid odor. Addressing these symptoms promptly prevents damage to adjacent components like the GROOVED STUD (0631311009).
