❓ FAQ
Yes. KH25501 shares the H 601/4 dimensions: 60 mm outer diameter, 18 mm inner diameter and 101 mm overall height. It drops into the same reservoir neck with no adapter.
It is a hydraulic steering filter for the power steering reservoir. It is not an engine lube filter, so it will not fit an engine oil housing even though the shape looks similar.
The Mercedes-Benz references are 001 184 22 25, 000 466 02 04 and 000 466 06 04. The same insert is also listed under Renault Trucks 50 00 814 407 and Scania 153 468.
The steering pump moves a smaller volume than the engine oil pump, so the media is sized for that flow. A deep pleat pack keeps pressure drop low when the oil is cold and the pump is at relief.
Yes. The gasket is supplied with the insert, so the reservoir neck can be resealed in the same operation instead of reusing the old seal.
