1. Disconnect hose assembly (1) from the trunnion oil pump. 2. Remove bolts (2) and pull transmission oil pump (3) from the torque converter housing.Install Transmission Oil Pump
1. Make sure the O-ring seals are installed in the pump body and put clean power train oil on them. Fill the pump with clean power train oil also. 2. Put transmission oil pump (1) in position and install the bolts to hold it. 3. Make sure the O-ring seal is installed in the end of hose assembly (2) and put clean power train oil on it. Connect hose assembly (2) to the power train oil pump.end by:a) install pilot and hydraulic pump **This operation is in the VEHICLE SYSTEMS DISASSEMBLY AND ASSEMBLY section.Disassemble Transmission Oil Pump
start by:a) remove transmission oil pump 1. Remove O-ring seals (2) and (3) from manifold (4).2. Remove the six bolts (1) that hold the pump together. 3. Remove cover (5) from the pump body. 4. If necessary, remove bearings (6) from cover (5). 5. Remove gears (7) and (8) from the pump body and manifold (4). 6. Remove body (9) from manifold (4). 7. If necessary, remove the four dowels (10) from body (9). 8. If necessary, remove bearings (11) from manifold (4).Assemble Transmission Oil Pump
1. Use tool group (A) and a press to install bearings (2) in manifold (3) until they are 1.5 0.5 mm (.059 .020 in.) below the surface of manifold (3). Make sure the bearing joints are 30° 15° from the centerline toward oil passage (1) as shown. 2. Install the four dowels (5) in body (4) until they extend 5.0 0.5 mm (.197 .020 in.) above the surfaces of the body. 3. Install body (4) on manifold (3). 4. Put clean oil on the bearings and install gears (6) and (7) in manifold (3). 5. Use tool group (A) and a press to install bearings (9) in cover (10) until they are 1.5 0.5 mm (.059 .020 in.) below the surface of cover (10). Make sure the bearing joints are 30° 15° from the centerline toward oil passage (8) as shown. 6. Put clean oil on the bearings and install cover (10) over the gears on body (4). 7. Install bolts (11) to hold the pump together. The pump gears must turn freely by hand after bolts (11) are tightened.8. Install O-ring seals (12) and (13) on the manifold.end by:a) install transmission oil pump
