ZF 4644.153.040 CLUTCH for WG 180/WG 200 | OEM Genuine Part

Overview

The ZF 4644.153.040 CLUTCH is a critical internal component engineered for the WG 180 and WG 200 series transmissions. This OEM genuine part serves as the primary engagement mechanism, managing torque transfer between the engine and the gearset. Positioned within the main drive assembly, the SKU 4644.153.040 ensures precise hydraulic actuation for smooth shifting under heavy loads. When paired with the 4644105475: DISCONNECTION unit, this clutch facilitates seamless power interruption during gear changes, reducing drivetrain stress in industrial applications.

Symptoms of Failure

When the 4644.153.040 clutch wears out, operators typically notice these specific failure modes:

• Delayed engagement or clutch slipping under load – A common long-tail search query, this manifests as hesitation when accelerating or a loss of torque during uphill operation.
• Oil leaks near the bell housing – Worn seals on the clutch assembly allow transmission fluid to escape, often visible as drips around the 4644101134: TRANSMISSION HOUSING.
• Erratic shifting or harsh engagement – The clutch fails to modulate pressure correctly, causing jarring gear changes that can damage the 4642303097: OUTPUT FLANGE over time.
• Burning smell from overheated friction material – Slipping generates excessive heat, degrading the clutch lining and potentially warping nearby components.

Technical Specifications

Compatibility

This OEM genuine clutch is specifically designed for ZF WG 180 and WG 200 series transmissions. It also fits select WG 160 variants with the same spline count and piston bore. The 4644.153.040 interfaces directly with the 0636020211: HEXAGON SCREW used to secure the clutch pack to the drum. For full assembly integrity, always verify the condition of the transmission housing and output flange during replacement.
