ZF 4657.362.002 ROTOR for WG210 | OEM Genuine Part

Overview

The ZF 4657.362.002 ROTOR is a precision-machined hydraulic component integral to the torque converter lock-up clutch assembly within the WG 210 Series transmission. This OEM genuine part, identified by SKU 4657.362.002, sits directly on the turbine shaft and modulates fluid flow to engage or disengage the lock-up clutch. It works in concert with the TRANSMISSION HOUSING to maintain correct hydraulic pressure. Without a properly functioning rotor, the transmission cannot achieve efficient power transfer from the engine to the drivetrain.

Symptoms of Failure

• Torque converter shudder at highway speeds: A worn rotor causes inconsistent lock-up clutch engagement, leading to vibration during cruising.
• Delayed or harsh lock-up engagement: When the rotor loses its sealing surface, hydraulic pressure drops, causing a noticeable lag or jolt when the clutch locks.
• Transmission fluid contamination: Degraded rotor material can shed fine metallic particles into the oil, often visible as glitter in the fluid pan.
• Overheating transmission under load: A failing rotor prevents proper clutch lock-up, generating excess heat that can damage the HOUS.FRONT SECT and surrounding seals.

Technical Specifications

Compatibility

This rotor is specifically engineered for the ZF WG 210 Series, but it also fits select models in the WG180 and WG200 families due to shared hydraulic architecture. It is a direct replacement for transmissions used in municipal buses, fire trucks, and heavy-duty construction vehicles. Always verify fitment with your HOUSING REAR PART dimensions, as variations exist between early and late production runs. The rotor interfaces with the CYLINDRICAL PIN that aligns the stator support, so ensure that pin is inspected during installation.
