(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 9 bolts. Uniformly tighten the
bolts in several passes.
Torque:
10 mm head: 8 N´m (80 kgf´cm, 69 in.´lbf)
12 mm head: 19.5 N´m (200 kgf´cm, 14 ft´lbf)
2. INSTALL CRANKSHAFT POSITION SENSOR
Torque: 8 N´m (80 kgf´cm, 69 in.´lbf)
3. INSTALL BAFFLE PLATE TO NO.1 OIL PAN
Torque: 8 N´m (80 kgf´cm, 69 in.´lbf)
4. 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 oil pan,
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 pan as shown in the illustra-
tion.
Seal packing: Part No. 08826-00080 or equivalent
Region ºXº is at the outer side of the bolt hole.
Region ºYº is at the inner side of the bolt hole.

Install a nozzle that has been cut to a or 3 - 4 mm
(0.12 - 0.16 in.) opening.
HINT:
Avoid applying an excessive amount to the surface.

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 the oil pan with the 17 bolts and 2 nuts. Uniformly
tighten the bolts and nuts in several passes.
Torque:
10 mm head: 8 N´m (80 kgf´cm, 69 in.´lbf)
12 mm head: 19.5 N´m (200 kgf´cm, 14 ft´lbf)
14 mm head: 37.2 N´m (380 kgf´cm, 27 ft´lbf)

NOTICE:

Be careful not to the damage the No.2 oil pan contact
surface of the No.1 oil pan.

Be careful not to damage the No.2 oil pan flange.
13. REMOVE OIL STRAINER
Remove the bolt, 2 nuts, oil strainer and gasket.
14. REMOVE NO.1 OIL PAN
(a) Remove the 2 bolts and No.1 exhaust pipe support brack-
et.
(b) Remove the 17 bolts and 2 nuts.
(c) Using a screwdriver, remove the oil pan by prying the por-
tions between the cylinder block and oil pan.
NOTICE:
Be careful not to damage the contact surfaces of the cylin-
der block and oil pan.
15. REMOVE BAFFLE PLATE FROM NO.1 OIL PAN
16. REMOVE CRANKSHAFT POSITION SENSOR
17. REMOVE OIL PUMP
(a) Remove the 9 bolts.
(b) Remove the oil pump by prying a screwdriver between the
oil pump and main bearing cap.
(c) Remove the O-ring.
