ZF 4616.308.035 INNER CLUTCH DISK for WG 65 | OEM Genuine Part

Overview

The ZF 4616.308.035 INNER CLUTCH DISK is a critical friction component engineered for the WG 65 series transmission. This OEM genuine part resides within the clutch pack assembly, where it transmits torque between rotating shafts during gear engagement. By providing precise frictional contact, it ensures smooth power flow and prevents slippage under heavy loads. The SKU 4616.308.035 is specifically designed to meet ZF’s exacting tolerances, making it a direct replacement for worn units in commercial vehicle drivelines. When installed alongside the 4616101059 TRANSMISSION HOUSING, this disk maintains proper alignment and hydraulic pressure within the clutch drum.

Symptoms of Failure

• Delayed or harsh gear engagement: A worn inner clutch disk causes hesitation or jerky shifts, particularly when accelerating from a stop.
• Transmission slipping under load: You may notice RPM spikes without corresponding speed increase, especially during uphill climbs or towing.
• Burning smell from transmission fluid: Excessive friction from a glazed disk generates heat, producing a distinct burnt odor in the oil.
• Metallic debris in the oil pan: As the friction material erodes, fine particles contaminate the fluid, often visible during routine changes.

Technical Specifications

Compatibility

This inner clutch disk is primarily used in the ZF WG 65 series, but it also fits several other heavy-duty transmissions from the same family. Compatible models include the WG 180, WG 200, and WG 250, all of which share similar clutch pack dimensions. For proper installation, ensure the 0636011038 HEXAGON SCREW and 0636011118 HEXAGON SCREW are torqued to specification. Additionally, the 0636016015 HEXAGON SCREW secures the clutch housing cover. Always verify your transmission model’s serial number before ordering.
