Start By:a. remove oil and water pump drive 1. Remove oil pump O-ring seal (4) from adapter (3).2. Remove the bolts and washers (2). Remove adapter (3) from shaft assembly (1). 3. Remove O-ring seals (6) and (7) from adapter (3).4. Use a press and tooling (A) to remove bearing (5) from adapter (3). 5. Remove bolts (9) to remove gears (8) and (10) from shaft assembly (1). 6. Remove O-ring seal (13) from water pump adapter assembly (12).7. Use a press and tooling (A) to remove bearing (11) from adapter assembly (12).Assemble Oil And Water Pump Drive
1. Lower the temperature of bearing (11) for water pump adapter (12). Use tooling (A) and install bearing (11) in adapter (12). Check the bore in the bearing after assembly. The bore in the bearing must be 75.00 0.06 mm (2.953 .002 in.). Install O-ring seal (13) on adapter (12). 2. Put gears (8) and (10) in position on shaft assembly (1) and install bolts (9) that hold the unit together. 3. Lower the temperature of bearing (5) for adapter (3). Make an alignment of the oil hole in the bearing with the oil hole in adapter (3) and use tooling (A) to install bearing (5). Make sure the bearing does not extend above the surface of the adapter. Make sure the inside diameter is 75.00 0.06 mm (2.953 .002 in.) after installation.4. Install O-ring seals (6) and (7) from adapter (3). 5. Put adapter (3) in position on shaft assembly (1) and install washers (2) to hold the unit together.6. Install O-ring seal (4) on adapter (3).End By:a. install oil and water pump drive
