Follow this procedure for assembly:Note: The seal installation tool is part of the replacement seal assembly.
Install ring assembly (2) and oil seal (1) into the pump housing. Install the oil seal dry. Do not lubricate the sealing lip. Use the correct installation tool and use a slow, even motion to press the seal into the pump housing.
Install shaft (6) through the oil seal and through the ring assembly.
Install thrust washer (7).
Lubricate the outside diameter of the ceramic ring and rubber seal (3) with clean water or with 207-1600 Rubber Lubricant.
Orient the polished face of the ceramic ring toward seal assembly (4). Use the installation tool and hand pressure to seat the ceramic ring and the rubber seal into the pump housing.
Remove spring (5) from the seal assembly. Lubricate the inside diameter of the seal assembly with clean water or with 207-1600 Rubber Lubricant.
Use the seal installation tool and hand pressure to install the seal assembly onto the shaft until the face of the seal assembly makes light contact with the face of the ceramic ring and rubber seal.
Install the spring onto the seal assembly.
Lubricate the shaft with clean engine oil. Place the shaft onto a fixture that will absorb the load and press impeller (8) onto the shaft until the face of the impeller is flush with the face of the shaft.
Lubricate the bore for O-ring seal (9) with clean engine oil.
Lubricate the bore for O-ring seal (10) with clean engine coolant.
Tighten studs (11) according to the specified torque.
Tighten nuts (12) according to the specified torque.
Lubricate the bore for O-ring seal (13) with glycerin.
Tighten adapter (14) according to the specified torque. Maximum leakage per minute for the water seal at 138 kPa (20 psi) of air pressure ... 20 cc (1.22 cu in)Maximum leakage per minute for the oil seal at 138 kPa (20 psi) of air pressure ... 24 cc (1.46 cu in)
