Information:
1. Remove oil supply tube (1) and suction bell and tube (2). 2. Remove bolts (3) that hold the oil pump to the cylinder block and remove oil pump (4).3. To install, put oil pump (4) in position on the cylinder block. Install the bolts that hold the oil pump to the cylinder block.4. Put clean engine oil on the O-ring seals of the tubes.5. Install oil supply tube (1), suction bell and tube (2).End By:a. install oil panDisassemble Oil Pump
Start By:a. remove oil pump 1. Remove the bolt and washer that hold the gear on the shaft.2. Use Tool (A) and remove drive gear (1) from the shaft. Remove the key from the shaft. 3. Remove retainer (3) for the bypass valve. Remove the spring and the bypass valve.4. Remove cover (2) from the pump body. 5. Use Tool (B) and remove the bearings from the cover. 6. Remove gears (5) from pump body (4).7. Use Tool (B) and remove the bearings from pump body (4).Assemble Oil Pump
1. Use Tool (B) to install the bearings in the pump body. Install the bearings so the joint in the bearings is 30 15 degrees from the center line of the oil pump outlet passage (2). 2. Install idler gear and drive gear (5) in the oil pump body (4). Put clean engine oil on the bearings and the gears. 3. Use Tool (A) and install the bearings in cover (2). Install the bearings so the joint of the bearing bores toward oil pump outlet passage (6).4. Install bypass valve (7), spring (8) and the retainer.5. Install the key on the shaft. 6. Install gear (1) on the shaft. Install the washer and bolt that hold the gear on the shaft. Be sure the pump turns freely after assembly.End By:a. install oil pump
