Earlier Pump
Later Pump3. Remove bolts (1) and pointer (3). Remove water pump (2) from the timing gear cover. The following steps are for installation of the water pump.4. Put the gasket and water pump (2) in position in the timing gear cover.5. Install pointer (3) and bolts (4).6. Put the vee belts in position on the engine.7. Use a belt tension gauge such as Borroughs Tool Company Part No. BT-33-72C or an equivalent and make an adjustment of the vee belts. Tighten new belts until the gauge indication is 120 5. Operate the engine at high idle for a minimum of 30 minutes after Step 8. Make another adjustment of the belt tension. The correct gauge indication for used belts is 90 10. Tighten the bolts that hold the alternator and raw water pump in position.8. Fill the cooling system with coolant to the correct level.Disassemble Water Pump (Earlier)
Start By:a. remove water pump Make a replacement of the shaft assembly, seal assembly, cup and seat with new parts when the water pump is assembled. 1. Use tooling (A) to remove pulley (1) from the shaft assembly.
The press must have a guard. The guard has been removed for photo illustration.
2. Use tool (B) and a press to remove the shaft assembly from the impeller and housing as shown.3. Use a hammer and punch to remove the seal assembly from the housing.4. Remove the seat and cup from the impeller.Assemble Water Pump (Earlier)
1. Use a press and tool (C) to install shaft assembly (2) in the housing as shown. 2. Use a press and tool (D) to install seal assembly (3) in the housing as shown. 3. Use a press and tool (E) to install pulley (1) on the shaft assembly as shown. 4. Put the cup and seat in position in impeller (4) and use tool (F) to install them by hand. Tools (G) and (H) have been replaced by an 8T0457 Installer.5. Put impeller (4) on the shaft assembly and use a press and tooling (E), (G) and (H) as shown to push the impeller on to the shaft assembly until tool (G) can just be moved between the housing and impeller. If the 8T0457 Installer is used, the impeller is pressed on until the installer makes contact with the housing.End By:a. install water pumpDisassemble Water Pump (Later)
Start By:a. remove water pump 1. Hold the pump shaft in a vise as shown, and remove the bolt and pulley (1).
The press must have a guard. The guard has been removed for photo illustration.
2. Use tooling (A) and a press to remove the shaft, seal and impeller from housing (2) as shown. 3. Remove bearing (3) from housing (2). 4. Remove spacer (4) from housing (2). 5. Use tool (B) to remove ring (5) from housing (2). Remove bearing (6) from housing (2). 6. Use a press and tool (C) to remove the shaft and seal assembly from impeller (7) as shown. 7. Install the seal assembly and shaft in housing (2) as shown. Use a press and tool (C) to remove the shaft from the seal assembly.Assemble Water Pump (Later)
1. Install bearing (1) in housing (3). Use tool (A) to install ring (2) that holds bearing (1) in position. 2. Install spacer (4) in housing (3). 3. Make sure the outside diameter of bearing (5) and the bore in housing (3) are clean and dry. Install bearing (5) in housing (3). Put Loctite No. 242 Adhesive/Sealant on outer bearing O.D. and housing bore before assembly. 4. 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 0.018 mm (.0007 in) loose to 0.008 mm (.0003 in) 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 75 7 N m (55 5 lb ft). 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. Tools (C) and (D) have been replaced by an 8T0457 Installer.8. Put tool (D) between impeller (8) and the pump housing.9. Use a press and tool (C) to install impeller (8) on the shaft until tool (D) can be moved between the housing and impeller. If the 8T0457 Installer is used, the impeller is pressed on until the installer makes contact with the housing.10. If the impeller is installed too far, and tool (D) cannot be removed, turn the pump over, and remove the pulley. Use tooling (E) and press to push the shaft out of the bearings enough to remove tool (D). Install the pulley, and tighten the bolt to a torque of 75 7 N m (55 5 lb ft).End By:a. install water pump
