Typical Example
(1) Diameter of the shaft at the seat area of the carbon seal assembly ... 44.450 0.020 mm (1.7500 0.0008 inch) (2) Seal assembly
Ring and water seal
Lubricate the housing bore with a light amount of glycerin.
Use the 8T-3034 Water Pump Seal Driver and hand pressure in order to install the seal (3) 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.
Seal assembly.
Remove the spring from the seat.
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. Note: 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. (3) Seal. Put a light coat of glycerin on the seal and in the housing bore at assembly. (4) Diameter of the impeller shaft at the location of the lip type seal ... 49.200 0.020 mm (1.9370 0.0008 inch) (5) Diameter of impeller shaft ... 64.850 0.020 mm (2.5531 0.0008 inch) (6) Diameter of the impeller shaft at the support end. ... 88.878 0.013 mm (3.4991 0.0005 inch) (7) Put 5P-3931 Anti-Seize Compound on the threads of the bolt at assembly. (8) Put a light coat of glycerin on the O-ring seal at assembly. Put a light coat of glycerin in the housing bore at assembly. (9) Put a light coat of clean engine oil on the seal at assembly. (10) Thickness of thrust washer ... 11.85 0.05 mm (0.467 0.002 inch)Width of groove in the impeller shaft for the thrust washer ... 12.00 0.05 mm (0.472 0.002 inch)End play for impeller shaft ... 0.05 to 0.25 mm (0.002 to 0.010 inch)
Illustration 2 g00525960 (11) Bore in impeller shaft bearing ... 65.00 0.06 mm (2.559 0.002 inch) (12) Dimension of impeller shaft bearing from surface of pump housing ... 92.5 1.0 mm (3.64 0.04 inch) (13) Bore in shaft support bearing ... 89.08 0.06 mm (3.507 0.002 inch)The shaft support bearing should be flush with the surface of the pump housing during installation.
