RING WATERPUMP BEARING

This key is designed for securing the water pump shaft in older Citroën vehicles. The part ensures a fixed connection between shaft and bearing housing, so rotation remains stable. Its construction supports correct alignment of the pump and limits unwanted movement. The design matches the dimensions of classic applications and can be used during maintenance or overhaul of the cooling system. The key fits a configuration with two identical heights and is suitable for installation together with standard bearings and seals inside the existing pump housing, without changes to the surrounding components or mounting positions.
