ZF 0501.323.205 MAGNET SEGMENT | OEM Genuine Part

Overview

The ZF 0501.323.205 MAGNET SEGMENT is a critical ferrous component engineered to capture metallic debris circulating within the transmission fluid of heavy-duty construction machinery. Positioned inside the lower sump area of the gearbox, this OEM genuine part (SKU: 0501.323.205) works in conjunction with the 4663101001: HOUSING to ensure that ferrous particles are trapped before they can damage precision-ground gears and clutch packs. By maintaining fluid cleanliness, this magnet segment directly extends the service life of the entire drivetrain assembly.

Symptoms of Failure

• Transmission fluid contamination with metallic sludge: When the magnet segment loses its magnetic retention capacity or cracks, ferrous particles circulate freely, causing accelerated wear on bearings and shafts.
• Intermittent gear engagement hesitation: Debris buildup on valve bodies leads to delayed shifts, particularly in ZF WG-series transmissions operating under heavy load.
• Unusual whining or grinding noises from the sump area: Loose metal fragments trapped between rotating elements produce audible distress signals, often mistaken for bearing failure.
• Reduced hydraulic pressure in the clutch circuit: Contaminated oil clogs fine mesh screens, resulting in slipping clutches and eventual transmission overheating.

Technical Specifications

Compatibility

This magnet segment is primarily specified for ZF WG180, WG200, and WG210 series powershift transmissions used in wheel loaders, graders, and dump trucks. It also fits select 4WG-200 and 6WG-200 variants. Always verify fitment by cross-referencing the 4663301025: COVER and 0631306816: CYLINDRICAL PIN in your assembly drawing. The segment is secured using a 0636100817: CAP SCREW to prevent dislodgement during high-vibration operation.
