INSPECTION
1. INSPECT RELIEF VALVE
Coat the valve with engine oil and check that it falls smoothly
into the valve hole by its own weight.
If the valve does not fall smoothly, replace the valve. If neces-
sary, replace the oil pump assembly.
2. INSPECT ROTOR BODY CIEARANCE
Using a thickness gauge, measure the clearance between the
driven rotor and pump body.
Standard body clearance:
0.10 − 0.18 mm (0.0039 − 0.0069 in.)
Maximum body clearance:
0.30 mm (0.0118 in.)
If the body clearance is greater than maximum, replace the ro-
tors as a set. If necessary, replace the oil pump assembly.
3. INSPECT ROTOR TIP CLEARANCE
Using a thickness gauge, measure the clearance between the
drive and driven rotor tips.
Standard tip clearance:
0.11 − 0.24 mm (0.0043 − 0.0094 in.)
Maximum tip clearance:
0.35 mm (0.0138 in.)
If the tip clearance is greater than maximum, replace the rotors
as a set.
4. INSPECT ROTOR SIDE CLEARANCE
Using a thickness gauge and precision straight edge, measure
the clearance between the rotors and precision straight edge.
Standard side clearance:
0.03 − 0.09 mm (0.0012 − 0.0035 in.)
Maximum side clearance:
0.15 mm (0.0059 in.)
If the side clearance is greater than maximum, replace the ro-
tors as a set. If necessary, replace the oil pump assembly.

REPLACEMENT
REPLACE CRANKSHAFT FRONT OIL SEAL
HINT:
There are 2 methods (A and B) to replace the oil seal, which are
as follows:
(a) If oil pump is removed from cylinder block.
(1) Using a screwdriver, pry out the oil seal.
(2) Using SST and a hammer, tap in a new oil seal until
its surface is flush with the oil pump body edge.
SST 09309−37010
(3) Apply MP grease to the oil seal lip.
(b) If oil pump is installed to the cylinder block.
(1) Using a knife, cut off the oil seal lip.
(2) Using a screwdriver, pry out the oil seal.
NOTICE:
Be careful not to damage the crankshaft. Tape the screw-
driver tip.
(3) Apply MP grease to a new oil seal lip.
(4) Using SST and a hammer, tap in the oil seal until its
surface is flush with the oil pump body edge.

INSTALLATION
1. INSTALL OIL PUMP
(a) Remove any old packing (FIPG) material and be careful
not to drop any oil on the contact surfaces of the oil pump
and cylinder block.
Using a razor blade and gasket scraper, remove all
the old packing (FIPG) material from the gasket sur-
faces and sealing grooves.
Thoroughly clean all components to remove all the
loose material.
Using a non−residue solvent, clean both sealing
surfaces.
(b) Apply seal packing to the oil pump, as shown in the il-
lustration.
Seal packing:
Part No. 08826−00080 or equivalent
Install nozzle that has been cut out to a 2 − 3 mm
(0.08 − 0.12 in.) opening.
HINT:
Avoid applying an excessive amount to the surface.
Parts must be assembled within 5 minutes of ap-
plication. Otherwise the material must be removed
and reapplied.
Immediately remove nozzle from the tube and rein-
stall cap.
(c) Place a new O−ring into the groove of the cylinder block.
(d) Install the oil pump to the crankshaft with the spline teeth
of the drive rotor engaged with the large teeth of the
crankshaft.

(e) Install the oil pump with the 8 bolts, and ground strap.
Torque:
Bolt A: 20 N·m (200 kgf·cm, 15 ft·lbf)
Bolt B: 42 N·m (420 kgf·cm, 31 ft·lbf)
2. INSTALL CRANK SHAFT POSITION SENSOR
3. INSTALL OIL PAN BAFFLE PLATE
4. INSTALL OIL STRAINER
Place a new gasket and install the oil strainer.
Torque:7.5 N·m (76 kgf·cm, 66 in.·lbf)
5. CLEAN OIL PAN
Remove any old packing (FIPG) material and be careful not to
drop any oil on the contacting surfaces of the, oil pan, cylinder
block and sealing grooves.
Using a razor blade and gasket scraper, remove all
the remaining seal packing (FIPG) material from the
gasket surfaces.
Thoroughly clean all components to remove all the
loose material.
Clean both sealing surfaces with a non−residue sol-
vent.
NOTICE:
Do not use a solvent which will affect the painted surfaces.
6. INSTALL OIL PAN
(a) Apply seal packing to the oil pan, as shown in the illustra-
tion.
Seal packing:
Part No. 08826−00080 or equivalent
Install a nozzle that has been cut to a 3 − 4 mm (0.12
− 0.16 in.) opening.
HINT:
Avoid applying an excess amount to the surface.
If parts are not assembled within 5 minutes of apply-
ing the seal packing, the effectiveness of the seal
packing is lost and the seal packing must be re-
moved and reapplied.
Immediately remove the nozzle from the tube and
reinstall the cap after using the seal packing.
(b) Install the oil pan with the 4 nuts and 15 bolts.
Torque:7.6 N·m (78 kgf·cm, 67 in.·lbf)
