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
(a) Place the drive and driven rotors into the oil pump body.
(see page LU±14)
(b) Inspect the rotors for the body clearance.
Using a feeler gauge, measure the clearance between
the drive and driven rotor tips.
Standard tip clearance:
0.060 to 0.180 mm (0.0024 to 0.0071 in.)
Maximum tip clearance: 0.18 mm (0.0071 in.)
If the tip clearance is greater than maximum, replace the rotors
as a set.
(c) Inspect the rotors for the side clearance.
Using a feeler gauge and precision straight edge, mea-
sure the clearance between the rotors and precision
straight edge.
Side clearance:
0.030 to 0.090 mm (0.0012 to 0.0035 in.)
Maximum body clearance: 0.09 mm (0.0035 in.)
If the side clearance is greater than maximum, replace the ro-
tors as a set. If necessary, replace the oil pump assembly.
(d) Inspect the rotor for the body clearance.
Using a feeler gauge, measure the clearance between
the driven rotor and body.
Standard body clearance:
0.250 to 0.325 mm (0.0098 to 0.0128 in.)
Maximum body clearance: 0.325 mm (0.0128 in.)
If the body clearance is greater than maximum, replace the ro-
tors as a set. If necessary, replace the oil pump assembly.
(e) Remove the drive and drive rotors.

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 3 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:
