Adjustment shim for water pump oil seal for Citroën 11CV and 15CV. This thin ring supports correct positioning of the seal in relation to the shaft and housing of the water pump. The shim promotes even load distribution on the seal and limits unwanted axial play. The product contributes to reduction of coolant leakage along the shaft. The adjustment shim is used during overhaul or installation of the water pump and fits common dimensions within this application range. The specific thickness allows alignment within tight tolerances inside the pump housing.
