4	1	292-5982 Face Seal Gp	Before assembly, lightly lubricate the bore with 5P-3975 Rubber Lubricant.
			Use the 8T-3034 Water Pump Seal Driver and hand pressure in order to install the water seal (5) and the ring together in the pump housing bore. Ensure that the polished face of the ring is toward the groove of the seal assembly.
			Before assembly, remove the spring from the seal.
			Put clean water on the seal assembly as the only lubrication for assembly. Do not get any grease or oil on the seal faces.
			Do not stretch the rubber of the seal assembly at installation. If the seal is stretched, the service life is shortened.
			Use the 8T-3034 Water Pump Seal Driver and hand pressure to install the seal assembly on the pump shaft until the seal face makes light contact with the smooth face of the ring.
			The seal assembly must rotate with the water pump shaft. Do not use any lubricant (except clean water) that will reduce the friction between the seal and the shaft.
			Install the carbon seal assembly spring.
