2. Drain the coolant from the cooling system.3. Loosen the tension on the V-belts, and disconnect the V-belts from the water pump pulley.4. Remove bolts (1) and pointer (3). Remove water pump (2) from the timing gear cover.Install Water Pump
1. Put the gasket and water pump (1) in position in the timing gear cover.2. Install the pointer and bolts to hold the water pump.3. Put the V-belts in position on the engine.4. Make an adjustment to the belt tension with a belt tension gauge such as a Borroughs Tool Company Part No. BU-33-95 or equivalent. The correct gauge indication is 534 22 N (120 5 lb.ft.) for a new belt. Operate the engine at high idle for a minimum of 30 minutes; then make another adjustment to the belt tension. The correct tension for a used belt is a gauge indication of 400 44 N (90 10 lb.). Used belt tension is for a belt which has more than 30 minutes of operation at rated speed of the engine.5. Fill the cooling system with coolant to the correct level. See the Maintenance Guide.6. Install fan. See Install Fan And Fan Drive.Disassemble Water Pump
START BY:a. remove water pump 1. Hold the pump shaft in a vise as shown, and remove the bolt and pulley (1). 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
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). Fill the chamber area between the housing and outside diameter of bearing (5) with 7M7456 Bearing Mount. Remove the excess bearing mount from the housing.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. 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 just be moved between the housing and impeller.10. If the impeller is installed too far and tool (D) can not 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
