Overview
The ZF 0501.216.106 MAGNET is an OEM genuine component engineered to capture ferrous debris circulating within the transmission fluid system. Positioned inside the sump or housing cavity of heavy-duty construction machinery transmissions, this magnet prevents metallic particles from re-entering the hydraulic circuit, thereby protecting valve bodies, clutch packs, and bearing surfaces from abrasive wear. The SKU 0501.216.106 is a direct replacement part that maintains the original magnetic flux density and corrosion resistance specified by ZF for long service intervals. When installed alongside the 4663101003 HOUSING, it ensures that captured contaminants remain isolated from the oil flow, while the 4663301026 COVER provides a sealed enclosure that prevents debris from escaping during operation.
Symptoms of Failure
- Transmission fluid contamination with metallic glitter – A worn or cracked magnet loses its ability to retain particles, allowing fine steel shavings to circulate and accelerate internal wear.
- Erratic shifting or gear hunting under load – Debris bypassing a degraded magnet can clog solenoid screens or valve orifices, causing pressure fluctuations and delayed engagement.
- Unusual whining or grinding noises from the transmission sump – Loose ferrous fragments that are not captured by a failing magnet can embed in bearing races or gear teeth, producing audible distress.
- Oil leaks around the housing interface – A magnet that has shifted or fractured can compromise the seal between the 0631306816 CYLINDRICAL PIN and the housing bore, leading to external seepage.

Compatibility
This magnet is designed for ZF power shift transmissions commonly used in wheel loaders, excavators, and telehandlers. Based on its form factor and magnetic rating, the 0501.216.106 is compatible with the following ZF models: WG180, WG200, WG210, and 4WG200 series. It also fits select variants of the Ecomat 2 and Ecomat 4 transmissions where the sump magnet is a serviceable insert. Always verify the housing bore diameter and retention method before installation; the 0636100817 CAP SCREW that secures the cover plate must be torqued to ZF specifications to prevent magnet displacement.
