Triumph TR5-250 Water Pump with Fixed Pulley - 6 Cylinder
TR5s, TR250s and the earliest TR6s were fitted with a water pump that had a detachable pulley. This type of pump is easily identified by the self locking nut that retains the pulley on the pump spindle. As a bonus, this design of water pump is repairable. It was replaced on later TR6s by a water pump and pulley assembly. This time the pulley was pressed on to the shaft. This unfortunately means that the pulley cannot easily be removed and therefore the pump is not easily repaired. The pump and pulley assembly, GWP201, will substitute for any previous TR5 and TR250 water pump application.
