Check the oil for deterioration, entry of water, discoloring .
or thinning.

Europe (‘IM-GE) and Australia *
Use API grade SE, SF or better and recommended
viscosity oil.
Europe (7M-GTE)
Use API grade SF or better and recommended
viscosity oil.
Others
Use API grade SC, SD, SE, SF or better and recom-
mended viscosity oil.
CHECK ENGINE OIL LEVEL
The oil level should be between the “L” and “F” marks on
the dipstick.
If low, check for leakage and add oil up to the “F” mark.
REMOVE OIL PRESSURE SENDER GAUGE
INSTALL OIL PRESSURE GAUGE
START ENGINE
Start engine and warm it up to normal operating tem-
perature.
MEASURE OIL PRESSURE
Oil pressure:
At idle 0.3 kg/cm2 (4.3 psi, 29 kPa1
or more
At 3,000 rpm 2.5 - 5.0 kg/cm
(36 - 71 psi, 245 - 490 kPa1
NOTE: Check for oil leakage after reinstalling the oil
pressure sender gauge.

~. -.--. . ._. I ”
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 does not, replace the relief valve.,If necessary, replace
the oil pump assembly.
INSPECT BODY CLEARANCE
Using a thickness gauge, measure the clearance between
the driven gear and pump body.
Standard clearance:
0.105 - 0.175 mm
(0.0041 - 0.0069 in.1
Maximum clearance: 0.2 mm (0.008 in.)
If the clearance is greater than maximum, replace the gear
or oil pump assembly.
INSPECT GEAR BACKLASH
Using a thickness gauge, measure the backlash as shown
in several places.
Standard backlash: 0.5 - 0.6 mm
(0.020 - 0.024 in.)
Maximum backlash: 0.9 mm (0.035 in.)
If the backlash is greater than maximum, replace the oil
pump drive shaft and driven gear.
INSPECT SIDE CLEARANCE
Using a thickness gauge and precision straight edge,
measure the clearance between the gears and precision
straight edge.
Standard clearance:
0.03 - 0.09 mm
(0.0012 - 0.0035 in.)
Maximum clearance: 0.15 mm (0.0059 in.)
If the clearance is greater than maximum, replace the drive
shaft and driven gear. If necessary, the oil pump assembly.

5. INSTALL OIL PUMP DRIVE SHAFT
Install the oil pump drive shaft, key, shaft drive gear,
spacer, and using snap ring pliers, install the snap ring.
INSTALL OIL PUMP DRIVEN GEAR
INSTALL OIL PUMP COVER
Install the oil pump cover with the five bolts.
Torque the bolts.

INSTALL RELIEF VALVE
Install the relief valve and spring with the relief valve plug.
Torque the plug.
Torque:
375 kg-cm (27 ft-lb, 37 N.m)
CHECK PUMP OPERATION
(a) Immerse the suction end of the pump into clean
engine oil and turn the shaft counterclockwise. Oil
should come out of the discharge hole.
(b) Close the discharge hole with your thumb, and turn
the shaft as before. The shaft should be difficult to
turn.

2. INSTALL OIL PAN
(a) Remove any old packing (FIPG) material and be care-
ful not to drop any oil on the contact surfaces of the
oil pan and cylinder block.
l Using a razor blade and gasket scraper, remove all
the packing (FIPG) material from the gasket sur-
faces.
0 Thoroughly clean all components to remove all the
loose material.
l Clean both sealing surfaces with a non-residue
solvent.
CAUTION: Do not use a solvent which will affect the
painted surfaces.
ib) Apply seal packing to the oil pan as shown in the
figure.
Seal packing: Part No. 08826-00080 or equivalent
0 Install a nozzle that has been cut to a 5 mm (0.20
in.) opening.
(c) Install the oil pan with the bolts and nuts.
