Turn the pump housing over and make sure that the bores in the bearings and spacer are in alignment. Install the shaft through the bearings from the impeller side of the housing. The shaft to bearing clearance can be .0007 in. (0.018 mm) loose to .0003 in. (0.008 mm) tight. If it is necessary to use a press to install the shaft, make sure the inner races of the bearings have support. 5. Install pulley (6) on the shaft and tighten the bolt to a torque of 55 5 lb. ft. (75 7 N m). 6. Put a new seal assembly (7) on the shaft as shown. 7. Use tool (B) and a press to install the seal assembly in housing (3). Do not use a hammer to install the seal. 8. Put tool (D) between impeller (8) and the pump housing.9. Use a press and tool (C) to install impeller (8) on
