Overview
The ZF 0501.209.080 SUCTION FILTER is a critical component designed to protect the hydraulic system in WG100, WG130, and WG131 transmissions. Positioned within the oil sump, this genuine OEM part ensures that transmission fluid entering the pump is free of contaminants, debris, and wear particles. The SKU 0501.209.080 is engineered to maintain consistent oil flow and pressure, directly supporting the longevity of internal assemblies such as the 2094104412 MAIN SHAFT and the 2094106010 SHIFT SYSTEM. Without this filter, particulate matter can rapidly degrade precision components, leading to costly downtime.
Symptoms of Failure
- Erratic gear engagement or slipping: A clogged suction filter restricts oil flow, causing delayed or harsh shifting. This is a common symptom when the 0501.209.080 becomes saturated with debris.
- Whining or cavitation noise from the pump: As the filter blocks, the transmission pump struggles to draw fluid, producing a high-pitched whine. This often precedes total pump failure.
- Overheating transmission: Reduced lubrication from a blocked filter increases friction, leading to elevated operating temperatures. This can warp the 2094304054 MAIN SHAFT if left unaddressed.
- Visible metal particles in the oil pan: When the filter fails to capture debris, metallic shavings appear during oil changes, indicating internal wear on components like the 2094206001 GEARSHIFT SHAFT.

Compatibility
This suction filter is specifically designed for ZF WG-series transmissions. Confirmed compatible models include WG100, WG130, and WG131. It is also suitable for certain variants of the WG180 and WG200 series when used in off-highway or industrial applications. Always verify the sump depth and mounting flange geometry against your transmission’s serial number. For rebuilds involving the 2094304054 MAIN SHAFT, replacing this filter is mandatory to prevent contamination of new bearings.
