[C] OIL PUMP OUTER ROTOR / INNER ROTOR REMOVAL
Make alignment dots on the outer and inner rotors for ease of reassembly.
INSTALLATION SERVICE POINTS
[A] OIL PUMP INNER ROTOR/OUTER ROTOR INSTALLATION
Apply engine oil to the rotors. Then install the rotors, ensuring that the alignment dots made at disassembly are properly aligned.
[B] OIL PUMP CASE ASSEMBLY INSTALLATION
1. Clean the gasket mating surfaces of oil pump case and cylinder block.
2. Apply a 3 mm (0.1 inch) diameter bead of sealant (Three bond 1217G or exact equivalent) to the oil pump case. Apply sealant as indicated by the broken line in the illustration; the grooves must be traced and the bolt holes must be surrounded with a bead of sealant.
3. Install the oil pump case assembly to the front of the cylinder block.
NOTE: Be sure to install the oil pump case quickly while the sealant is wet (within 15 minutes).
4. Tighten the oil pump case mounting bolts to the specified torque.
Tightening torque: 14 ± 1 Nm (122 ± 9 in-lb)
NOTE: After installation, keep the sealed area away from oil and coolant for approximately one hour.
[C] CRANKSHAFT FRONT OIL SEAL INSTALLATION
1. Install the guide of special tool MD998717 to the front end of the crankshaft.
2. Apply engine oil to the lip area of a new oil seal and push it in until it contacts the oil pump case.
3. Using special tool MD998717, press-fit the oil seal into the oil pump case.
[D] OIL FILTER INSTALLATION
1. Clean the installation surface of the filter bracket.
2. Apply engine oil to the O-ring of the oil filter.
3. Install the oil filter to the bracket and tighten it to the specified torque.
Tightening torque: 14 ± 2 Nm (122 ± 17 in-lb)
4. If no torque wrench can be used for tightening, use the following procedure.
1) Screw in the oil filter until its O-ring contacts the oil filter bracket.
2) Tighten the oil filter 1 turn.
[E] ENGINE OIL PRESSURE SWITCH INSTALLATION
CAUTION
Keep the end of threaded portion clear of sealant. Avoid an overtightening.
Apply sealant (Three bond 1215 or equivalent) to the thread of engine oil pressure switch.
[F] OIL PAN, UPPER INSTALLATION
1. Clean both gasket surfaces of the upper oil pan and cylinder block.
2. Apply a 4 mm (0.2 inch) diameter bead of sealant (Three bond 1217G or exact equivalent) to the upper oil pan. Apply sealant as indicated by the broken line in the illustration the grooves must be traced and the bolt holes must be surrounded with a bead of sealant.
CAUTION
When installing the upper oil pan, be sure not to expel the sealant from the oil pan flange at portion A in the illustration.
3. Install the oil pan to the bottom of the cylinder block.
NOTE: Be sure to install the oil pan quickly while the sealant is wet (within 15 minutes).
4. Tighten the upper oil pan bolts in the sequence shown.
Tightening torque: 9.0 ± 3.0 Nm (80 ± 26 in-lb)
NOTE: After installation, keep the sealed area away from the oil and coolant for approximately one hour.
[G] OIL PAN, LOWER INSTALLATION
1. Clean both gasket surfaces of the upper and lower oil pans.
2. Apply a 4 mm (0.2 inch) diameter bead of sealant (Three bond 1217G or exact equivalent) to the lower oil pan. Apply sealant as indicted by the broken line in the illustration; the grooves must be traced and the bolt holes must be surrounded with a bead of sealant.
3. Install the lower oil pan to the upper oil pan.
NOTE: Be sure to install the oil pan quickly while the sealant is wet (within 15 minutes).
4. Tighten the lower oil pan bolts in the sequence shown.
Tightening torque: 11 ± 1 Nm (98 ± 8 in-lb)
NOTE: After installation, keep the sealed area away from oil for approximately one hour.
[H] DRAIN PLUG GASKET INSTALLATION
