TYPE="TABLE" @@@-->Note: Reposition the auxiliary water pump on suitable cribbing. Ensure that the shaft assembly is supported. Carefully inspect the surface of the seal assembly. If the surface is cracked or scratched, discard the seal assembly and obtain a new seal assembly for installation. Ensure that the faces of the seal assembly are clean.
Lubricate the stationary segment of seal assembly (21) with a solution of water and five percent soap. Use hand pressure to install the stationary segment of seal assembly (21) into the pump body. After the seal is installed, wipe the surface dry. Lubricate the rotating segment of seal assembly (21) with a solution of water and five percent soap. Use hand pressure to install the rotating segment of seal assembly (21) over the shaft assembly.

Determine the thickness of the shims for the body. The shims will be used in order to obtain a Clearance (X) of 0.20 to 0.30 mm (0.008 to 0.012 inch) between the top face of the impeller and the top face of the ring.The ring should be raised slightly above the face of the impeller.Place a straight edge on the face of the ring across the impeller. Use a feeler gauge to measure the Dimension between the face of the impeller and the bottom of the straight edge.Note: If necessary, remove the bolts and use the forcing holes to raise the body in order to install the shims.
After Clearance (X) is correct, tighten bolts (17) from Step 14 to a torque of 22 4 N m (195 35 lb in).
