ZF 0501.214.009 OUTER CLUTCH DISK for WG158/WG200

Overview

The ZF 0501.214.009 OUTER CLUTCH DISK is a critical friction component engineered for the WG158 and WG200 series transmissions. This OEM genuine part sits within the clutch pack assembly, where it transfers torque between rotating elements during gear shifts. As a steel-backed friction plate, it engages with the inner clutch disks to lock or release planetary gear sets, enabling smooth power flow through the drivetrain. The SKU 0501.214.009 is precision-machined to ZF’s original tolerances, ensuring consistent clamping force and heat dissipation under heavy-duty industrial loads. When paired with a properly sealed TRANSMISSION HOUSING, this disk maintains optimal hydraulic pressure within the clutch circuit.

Symptoms of Failure

• Delayed or harsh gear engagement: Worn friction material causes slipping, especially when shifting from neutral to drive under load.
• Burning smell from transmission fluid: Overheated clutch disks generate acrid odors due to excessive friction and glazing.
• Erratic shift timing: The transmission may hunt for gears or flare during upshifts as the outer disk fails to grip properly.
• Metallic debris in oil pan: Flaking friction material or worn steel separator plates contaminate the fluid, often requiring replacement of the HOUS.FRONT SECT and related seals.

Technical Specifications

Compatibility

This outer clutch disk is designed for ZF WG158 and WG200 series transmissions, commonly found in medium-duty trucks, buses, and construction equipment. It directly replaces OEM part 0501.214.009 in clutch packs A, B, and C. Compatible models include WG158, WG180, WG200, and WG210 variants. Always verify the spline count and stack height against your existing assembly. For proper installation, ensure the OIL TUBE is clear of debris and the HOUSING REAR PART is torqued to factory specifications.
