Note: For a complete description of Type 1 and Type 2 engines, refer to the Disassembly and Assembly, "Engine Design" topic.
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Note: The water pump for Type 2 Engines and 7BJ Engines is not serviceable. Contact your Caterpillar dealer for more replacement information.
Clean the inside of the pump body. Ensure that the bearing bore and the counterbore for the water seal are particularly clean.
Apply 4C-9507 Retaining Compound to the outer surface of the bearing. Keep the compound away from the ends of the bearing.

Support the gear end of the water pump body.
Place the bearing and shaft (6) square in the pump body. Ensure that the shortest end of shaft (6) is in housing (9) .
Use a suitable press and a suitable adapter that will apply force to the bearing. The adapter should not apply force to the shaft. Press the bearing onto the shaft until the end of the bearing is level with the bottom of the counterbore for the water seal.Note: Remove the excess compound from the end of the bearing.
Install seal (7) .

Ensure that the water seal is not contaminated by oil or grease. Hold the seal only by the edge of the flange. Do not damage the ring of green sealant that is applied to the body of the water seal behind the flange.
Hold water seal (5) by the edge of the flange. Push the seal onto shaft (6) until the seal is against the chamfer of the counterbore. Only apply force to the outer flange of the seal.Note: Ensure that the wide end of the seal is toward the bearing and that the seal is square with the counterbore.
Continue to apply force and hold water seal (5) for ten seconds. This ensures that the water seal will remain in place.
Hold the water pump with the gear end of the shaft on a suitable support. Use a flat bar in order to press impeller (8) onto shaft (6) to a depth of 8.30 0.20 mm (.320 .010 inch). After installation, ensure that the impeller will turn freely.Note: Apply 4C-9507 Retaining Compound to impeller (8) if the original impeller is used. Remove excess compound after assembly.

Lubricate oil seal (3) with clean engine oil. Install oil seal (3) with the flat surface toward the bearing. Press oil seal (3) into the body with a suitable adapter until the rear of the seal is level with the end of the pump.
Continue to apply force and hold oil seal (3) in position for ten seconds. This ensures that the seal will remain in place.
Press gear (4) onto shaft (6) to a depth of 1.60 1.00 mm (.015 .005 inch) .Note: Apply 4C-9507 Retaining Compound to gear (4) if the original gear is used. Remove excess compound after assembly.

Install a new gasket and cover (2) on the pump body.
Install six bolts (1). Tighten the bolts to a torque of 9 N m (80 lb in).End By: Install the water pump. Refer to Disassembly and Assembly, "Water Pump - Install".
