This long oil pump shaft provides mechanical drive for the oil pump in classic Citroën engines. The shaft links the engine drive to the internal pump and supports pressure generation in the lubrication system. Its slim design with fixed diameter and length fits within the housing of specific engine versions. The surface allows installation with bearings and seals. The shaft is suitable for replacement during overhaul or restoration of the lubrication function. The component contributes to stable oil supply to bearings and moving parts during operation under standard load conditions in normal engine use.
