Overview
The ZF 0501.208.626 OIL FILTER is a critical component engineered specifically for the lubrication circuit of ZF WG100, WG130, and WG131 powershift transmissions. This OEM genuine part ensures that hydraulic fluid remains free of particulate contaminants, which is essential for maintaining precise clutch engagement and valve body operation. The SKU 0501.208.626 sits directly within the transmission’s oil sump or external filter housing, capturing debris before it can circulate through the torque converter and planetary gear sets. Regular replacement of this filter is mandatory to prevent abrasive wear on precision-machined surfaces.
Symptoms of Failure
- Erratic gear engagement and slipping: A clogged 0501.208.626 restricts oil flow, causing delayed or harsh shifting, especially under load. This is a common search query for “ZF transmission slipping when hot.”
- Visible oil leaks around the filter housing: When the filter bypass valve sticks or the filter media collapses, internal pressure spikes can force fluid past seals, leading to “ZF transmission oil leak from filter area.”
- Overheating transmission fluid: Restricted flow reduces the cooler’s efficiency. Operators often search for “ZF WG100 transmission overheating” when this filter is overdue for service.
- Contaminated oil on the dipstick: A failed filter allows debris to recirculate, turning the fluid dark or metallic, which is a direct indicator of “transmission oil filter failure symptoms.”

Compatibility
This oil filter is engineered for the ZF WG series of powershift transmissions. It is directly compatible with the WG100, WG130, and WG131 models, which are commonly found in agricultural tractors, telehandlers, and construction loaders. It also fits select variants of the WG180 and WG200 transmissions where the filter head uses the same thread pattern and bypass specification. Always verify the filter head condition; if replacing the housing, consider the 2095101022: TRANSMISSION HOUSING or the 2095301025: TRANSMISSION HOUSING for complete assembly renewal.
During installation, the 0634304731: O-RING must be replaced to ensure a leak-free seal against the housing. The filter canister is secured with a 4475280150: SCREW PLUG in certain remote-mount configurations. For optimal performance, always pair this filter with fresh hydraulic fluid and inspect the transmission housing for cracks or warpage.
