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 it doesn't, replace the relief valve. If necessary, replace the oil
pump assembly.
2. INSPECT DRIVE AND DRIVEN ROTORS INTO OIL
PUMP BODY
Place the drive and driven rotors into the oil pump body with the
mark facing upward.
3. INSPECT ROTORS FOR TIP CLEARANCE
Using a feeler gauge, measure the clearance between the drive
and driven rotor tips.
Standard tip clearance:
0.110 - 0.240 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 ROTORS FOR SIDE CLEARANCE
Using a feeler gauge and precision straight edge, measure the
clearance between the rotors and precision straight edge.
Standard side clearance:
0.030 - 0.090 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.
5. INSPECT ROTOR FOR BODY CLEARANCE
Using a feeler gauge, measure the clearance between the driv-
en rotor and body.
Standard body clearance:
0.100 - 0.175 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.
6. REMOVE DRIVE AND DRIVE ROTORS

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 groove.
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 illustra-
tion.
Seal packing: Part No. 08826-00080 or equivalent
NOTICE:
Avoid applying an excessive amount to the surface. Be par-
ticularly careful near oil passage.
Install a nozzle that has been cut to a 2 - 3 mm (0.08
- 0.12 in.) opening.
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) Install a new O-ring to the cylinder block.
(d) Engage the spline teeth of the oil pump drive gear with the
large teeth of the crankshaft, and slide the oil pump on the
crankshaft.
(e) Install the oil pump with the 8 bolts. Uniformly tighten the
bolts in several passes.
Torque:
15.5 N´m (160 kgf´cm, 11 ft´lbf)
for 12 mm head and 6 mm hexagon head
30.5 N´m (310 kgf´cm, 22 ft´lbf) for 14 mm head
HINT:
Use a 6 mm hexagon wrench for the hexagon head bolt.
Each bolt length is indicated in the illustration.

3. INSTALL NO.1 OIL PAN
(a) Remove any old packing (FIPG) material and be careful
not to drop any oil on the contact surfaces of the No.1 oil
pan, cylinder block, oil pump and rear oil seal retainer.
Using a razor blade and gasket scraper, remove all
the old packing (FIPG) material from the gasket sur-
faces and sealing groove.
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 No.1 oil pan as shown in the il-
lustration.
Seal packing: Part No. 08826-00080 or equivalent
Install a nozzle that has been cut to a 2 - 3 mm (0.08
- 0.12 in.) opening.
Parts must be assembled within 5 minutes of ap-
plication. Otherwise the material must be removed
and reapplied.
