Overview
The ZF 0501.208.244 SUCTION FILTER is a critical hydraulic component engineered specifically for the WG250 and WG260 transmission series. Positioned within the oil sump, this genuine OEM part ensures that only clean, debris-free transmission fluid enters the hydraulic pump, safeguarding internal valves and clutch packs from premature wear. The SKU 0501.208.244 is the direct replacement for the original factory-installed filter, guaranteeing a precise fit and optimal flow rate. When paired with a robust TRANSMISSION HOUSING, this filter maintains the system’s hydraulic integrity under heavy load conditions.
Symptoms of Failure
When the ZF 0501.208.244 suction filter becomes clogged or collapses, operators often notice delayed gear engagement during cold starts, as restricted oil flow prevents proper clutch pack pressurization. Another common sign is intermittent gear slipping under load, particularly when climbing grades or hauling maximum payloads. A third failure symptom includes erratic shift quality—harsh upshifts followed by soft downshifts—caused by cavitation in the hydraulic circuit. Finally, persistent low transmission oil pressure warnings on the dash display frequently trace back to a blocked suction filter, even when fluid levels appear normal.

Compatibility
This suction filter is a direct fit for the ZF WG250 and WG260 series transmissions commonly found in mid-range construction and agricultural machinery. It also serves as a replacement in the WG180 and WG200 models where the hydraulic pump suction port configuration matches. For complete assembly integrity, always inspect the HOUSING and COVER for cracks or distortion during filter replacement. Secure the unit using a HEXAGON SCREW torqued to factory specifications to prevent fluid bypass.
