Remove bearing (15) from the pump housing.Assemble Auxiliary Water Pump
1. Make sure the oil hole in the bearing is in alignment with the oil passage in housing (16). Use tool group (A) and a press to push the bearing in housing (16) until it is 1.5 0.5 mm (.06 .02 in) below the surface of housing (16). The inside diameter of the bearing must be 75.000 0.055 mm (2.9528 .0022 in). 2. Use tool group (A) to install the lip-type seal in housing (16). Make sure the lip of the seal is toward the bearing as shown. Put clean engine oil on the lip of the seal. 3. Install shaft (8) in the pump housing. Install retainer washers (13), the shims and bolts to hold shaft (8) in the pump housing. 4. Put clean engine oil on the bearing in the pump housing, and install shaft (1) and retainer washers (12) over shaft (8). Install the bolts to hold retainer washers (12) to the pump housing.
Clean water only is permitted for use as a lubricant for assembly. Do not damage or put hands on the wear surfaces of the carbon ring or the ceramic ring. Install the ceramic ring with the smoothest face of the ring toward the carbon seal assembly.
5. Install ceramic seal ring (11) in the rubber seal. Put clean water on the rubber seal and ceramic seal ring for lubrication. Use hand pressure and the tool (which is with the replacement seal group) to install the seal and seal ring as shown. 6. Remove the spring from carbon seal assembly (10). Put clean water on the inside diameter of the seal assembly for lubrication. Use hand pressure and the tool (which is with the replacement seal group) to push seal assembly (10) on the shaft until seal faces make light contact. 7. Install spring (9) on carbon seal assembly (10). 8. Put impeller (7) in position on the pump shaft as shown. 9. Install the bolt and washer that hold impeller to the pump shaft. Tighten the bolt to a torque of 38 4 N m (28 3 lb ft). 10. Install O-ring seal (17) around adapter (5) and put a small amount of clean engine oil or glycerin on it.11. Put adapter (5) in position, and install the bolts to hold it to the pump housing. 12. Put gear (2) in position on shaft (1), and install the bolts to hold gear (2). 13. Install O-ring seals (3) and (4) in the pump
