INSPECTION
1. INSPECT PRESSURE REGULATOR VALVE
Coat the valve piston with engine oil and check that it falls
smoothly into the valve hole by its own weight.
If necessary, replace the valve.
2. INSPECT ROTOR BODY CLEARANCE
Using a feeler gauge, measure the clearance between the driv-
en rotor and pump body.
Standard clearance:
0.10 - 0.16 mm (0.0039 - 0.0063 in.)
Maximum clearance:
0.20 mm (0.0079 in.)
If the clearance is greater than maximum, replace the oil pump
rotor set and/or pump body.
3. INSPECT TIP CLEARANCE
Using a feeler gauge, measure the clearance between both ro-
tor tips.
Standard clearance:
0.03 - 0.14 mm (0.0012 - 0.0055 in.)
Maximum clearance:
0.20 mm (0.0079 in.)
If the clearance is greater than maximum, replace the oil pump
rotor set.
4. INSPECT SIDE CLEARANCE
Using a feeler gauge and flat block, measure the side clearance
as shown.
Standard clearance:
2.91 - 2.97 mm (0.1145 - 0.1169 in.)
Minimum clearance:
2.90 mm (0.1142 in.)
If the clearance is greater than maximum, replace the oil pump
rotor set and/or pump body.

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 contact
surfaces and sealing grooves.

Thoroughly clean all components to remove all the
loose material.

Using a non-residue solvent, clean both sealing
surfaces.
(b) Place the driven rotors into the pump body with the marks
facing the front.
(c) Align the pully and oil pump drive shaft.
(d) Using a vise, install the oil pump pully and nut.
Torque: 37 N´m (370 kgf´cm, 27 ft´lbf)
(e) Apply seal packing to the oil pump as shown in the illustra-
tion.
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.
HINT:
Avoid applying an excessive amount to the surface.
