Overview
The ZF 0501.330.190 FILTER HEAD is a critical hydraulic component designed for the WG100, WG130, and WG131 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 filtered before circulating through the valve body and torque converter. The SKU 0501.330.190 sits directly on the transmission housing, where it channels pressurized oil through the filter element, removing contaminants that can cause premature wear. When paired with a 2093109022 DIFFERENTIAL, this filter head helps maintain consistent lubrication pressure across the entire drivetrain.
Symptoms of Failure
- Hydraulic oil leaks at filter base: A worn gasket or cracked filter head housing allows transmission fluid to seep out, often visible as drips beneath the vehicle after shutdown.
- Erratic gear engagement or slipping: When the filter head fails to maintain proper flow, insufficient hydraulic pressure causes delayed shifts or clutch slip during acceleration.
- Whining noise from transmission pump: A restricted or bypassing filter head forces the pump to cavitate, producing a high-pitched whine that intensifies under load.
- Overheating transmission fluid: Restricted oil flow through a degraded filter head reduces cooling capacity, leading to elevated operating temperatures and potential seal damage.

Compatibility
This genuine ZF filter head is engineered for the WG100, WG130, and WG131 series transmissions commonly found in medium-duty trucks, buses, and construction equipment. It also fits select WG180 and WG200 variants that share the same filter housing interface. For complete drivetrain reliability, inspect the 0750117075 TAPER ROLLER BEARING and the 2093209096 DIFFERENTIAL during filter head replacement. Always verify the 2093309073 DIFF.HOUSING for cracks or warping when servicing the lubrication circuit.

Frequently Asked Questions
Q: Can the 0501.330.190 filter head be reused after cleaning?
A: ZF recommends replacement rather than reuse. The aluminum housing can develop micro-cracks from thermal cycling, and the internal sealing surfaces degrade over time, leading to bypass leakage.
Q: What torque specification should I use for the mounting bolts?
A: Tighten the four M8 bolts to 22 Nm (16 ft-lbs) in a cross pattern. Over-torquing can distort the filter head and cause internal leakage.
Q: Does this filter head fit the ZF WG180 transmission?
A: Yes, the WG180 uses the same filter head interface as the WG130 series. However, always verify the port orientation matches your specific transmission housing casting number.
