31100-94401 Suzuki BOLT

1. Remove bolt (1) that holds suction bell (3) to the oil pan plate. Bend the locks away from bolts (2). Remove bolts (2) that hold the suction tube to the oil pump. Remove the gasket from between the suction tube flange and the oil pump. 2. Remove two bolts (5) that hold the scavenge tube manifold (6) to the oil pump. Remove manifold (6) from tube (4). Check O-ring seals on tube (4). Make a replacement of the seals if necessary. Remove bolts (7) and remove the oil pump.Install Oil Pump
1. Put oil pump (1) in position under the cylinder block and install the bolts that hold it. 2. Install a new gasket between the oil pump and the scavenge tube manifold. Install manifold on tube. Install bolts (2) that hold manifold to oil pump.3. Put suction tube (3) in position on the oil pump. Make sure there is a new gasket between the flange on the suction tube and the oil pump.4. Install the bolts that hold the suction tube to the oil pump. Bend the locks against the bolts. Install the bolt that holds the bracket on the suction bell to the oil pan plate.end by:a) install oil panDisassemble Oil Pump

Remove the drive gear from the shaft with tooling (A).5. Remove the key from the pump shaft.6. Remove bolts (3) from the pump body. 7. Remove body (8), two gears (7), keys and spacer (4) from the pump.8. Remove two shafts (5) and the gears.9. Remove bolts (6), the cover and the pressure relief valve from the body. 10. Remove the bearings from the oil pump body assembly and the scavenge pump body assembly with tooling (C).Assemble Oil Pump
1. Install the bearings in the scavenge pump body assembly with tooling (A) as follows: a) Put bearings (1) in position on the inside of the scavenge pump body assembly with the chamfer on the bearing as shown. Install the bearing until it is .060 in. (1.52 mm) below the inside machined surface of the scavenge pump body assembly. Make sure the joints in the bearings are at an angle of 30° 15° from the center line through the bores in the scavenge pump body assembly as shown.2. Install the bearings in oil pump body assembly with tooling (A) as follows: a) Put bearing (2) in position on the inside of the oil pump body assembly with the chamfer on the bearings as shown. Install the bearings until they are even with the outside surface of the oil pump body assembly.3. Check the condition of the relief valve. Check the condition and specifications for all the parts of the oil pump before it is assembled. See OIL PUMP in SPECIFICATIONS.4. Put clean engine oil on all of the parts of the oil pump. 5. Install pressure relief valve (3), cover (4) and bolt (5) in the oil pump body assembly. 6. Install gears and shafts (6) in the oil pump body assembly.7. Install spacer (7) and the two keys in shafts (6). 8. Install two gears and scavenge pump body assembly (8).9. Install key (9), drive gear (11), the washer and bolt (10). Tighten the bolt to a torque of 32 5 lb. ft. (43 7 N m).10. Install the bearing in the idler gear with tooling (B) until it is even with the outside surface of the gear.11. Install the idler gear.
The oil pump must turn freely by hand after it is assembled.
