Overview
The ZF 4646.351.182 INNER CLUTCH DISK is a critical friction component engineered for the WG 250, WG 260, and WG 310 transmission series. This OEM genuine part resides within the multi-plate clutch pack assembly, where it transmits torque between rotating shafts during gear engagement. As a wear item, the SKU 4646.351.182 directly influences shift quality and power delivery. When paired with a robust TRANSMISSION HOUSING, this disk ensures consistent hydraulic pressure distribution across the clutch stack, preventing premature failure in high-torque industrial applications.
Symptoms of Failure
- Delayed or harsh gear engagement: Worn friction material causes the clutch pack to slip before fully locking, resulting in a noticeable lag or jolt when shifting from neutral to drive.
- Transmission overheating: Excessive slippage from a degraded inner clutch disk generates abnormal heat, often indicated by a burnt smell or rising oil temperature gauges.
- Loss of power under load: When the disk cannot maintain friction, the transmission may momentarily lose torque transfer, particularly during uphill climbs or heavy hauling.
- Metallic debris in transmission fluid: As the friction lining disintegrates, fine metal particles contaminate the oil, visible during routine fluid changes or filter inspections.
