Overview
The ZF 0501.223.274 FILTER HEAD is a critical hydraulic component engineered specifically for the BP210 and BP230 transmission series. This OEM genuine part serves as the mounting interface and fluid distribution hub for the main oil filter assembly, ensuring that transmission fluid is properly directed through the filtration media before returning to the valve body and torque converter circuit. The SKU 0501.223.274 integrates directly with the TRANSMISSION HOUSING to maintain consistent oil pressure and cleanliness. Without a properly sealed filter head, particulate contamination can bypass filtration and accelerate internal wear across the entire drivetrain.
Symptoms of Failure
- External oil seepage at filter mounting boss: A cracked or warped filter head gasket surface allows transmission fluid to weep down the side of the HOUS.FRONT SECT, leaving visible drips on the bell housing.
- Erratic shift quality under load: When the filter head bypass valve sticks open due to debris, unfiltered oil reaches the control solenoids, causing delayed or harsh gear engagement.
- Low line pressure warning codes: A restricted or collapsed filter head internal passage reduces pump output, triggering diagnostic trouble codes for insufficient main pressure.
- Overheating transmission fluid: Restricted flow through a degraded filter head forces the torque converter to operate at higher slip speeds, elevating sump temperature beyond normal operating range.

Compatibility
This filter head is designed for ZF BP210 and BP230 series powershift transmissions commonly found in mobile construction equipment and material handlers. It also fits the WG180 and WG200 series when the HOUSING REAR PART is configured with the same filter pad geometry. For installations using the CASE variant with offset filter ports, verify the mounting bolt pattern matches the 0501.223.274 flange before assembly. Always replace the filter head when performing a major transmission overhaul to prevent debris from the old unit contaminating the new filter element.
