3) Using rod with outer diameter of 30 mm (1.18 in), press pis-
ton pins out.
11. Remove lower cylinder block.
+The lower cylinder block is the lower part of the cylinder
block, which works as the main bearing cap (beam) and oil
pan mounting face.
1) Remove mounting bolts for engine sub-attachment shown by
arrows in the figure.
2) Loosen and remove mounting bolts in the reverse order
shown in the figure.
3) Insert flat-bladed screwdriver into 5 locations shown by
arrows in the figure. Lift lower cylinder block evenly, and
remove liquid gasket.
CAUTION:
Prevent mating faces from being damaged.
4) When removing lower cylinder block, use slot to prevent
dowel pin from interfering with engine sub-attachment.
+No part No. is given to lower cylinder block, because it is
machined with the cylinder block.
12. Remove crankshaft.
13. Remove main bearings and thrust bearings from cylinder
block and lower cylinder block.
CAUTION:
Check mounting positions. Keep them to avoid confusion.

positions on cylinder block and main bearing caps.
2) Install thrust bearings on both sides of No. 4 housing on cyl-
inder block.
+Install thrust bearings with oil groove facing to crankshaft arm
(outside).
3) Being careful with the direction, install main bearings.
+Install main bearings with the oil holes and grooves onto the
cylinder block side, and those without oil holes and grooves
onto the lower cylinder block side.
+While installing bearings, apply engine oil to bearing surfaces
(inside). Do not apply oil to rear surfaces, but clean them
completely.
+Align stopper notches on bearings to install them.
+Check that the oil holes on the cylinder block body are mated
with the oil hole positions on the bearings.
3. Install crankshaft to cylinder block.
+While rotating crankshaft by hand, check for smooth rotation.
4. Install lower cylinder block.
+Apply a continuous bead of liquid gasket to lower cylinder
block as shown in the figure.
+Using slots on engine sub-attachment, install the lower cyl-
inder block to the cylinder block, avoiding interference of
dowel pins.
5. Tighten lower cylinder mounting bolts to the torque shown
below in 3 consecutive steps in the order shown in the fig-
ure.
Unit: Nzm (kg-m, ft-lb)
Main bolt (Nos. 1 - 10) Sub-bolt (Nos. 11 - 20)

ANCEº.
12. Install rear oil seal and retainer assembly.
+Apply a continuous bead of liquid gasket to rear oil seal and
retainer assembly as shown in the figure.
13. Press fit pilot bushing into flywheel (M/T model).
1) Using drift with outer diameter of 35 mm, press fit spacer until
it is in contact with the flywheel to prevent displacement at
removal.
2) Using drift with outer diameter of 20 mm, press fit pilot bush-
ing by the length shown in the figure.

Nickel Metal Hydride Battery Replacement
CONSULT-II contains a nickel metal hydride battery. When replacing the battery obey the following:
WARNING:
Replace the nickel metal hydride battery with Genuine CONSULT-II battery only. Use of another bat-
tery may present a risk of fire or explosion. The battery may present a fire or chemical burn hazard
if mistreated. Do not recharge, disassemble or dispose of in fire.

Oil Pressure Check
WARNING:
+Be careful not to burn yourself, as the engine and oil
may be hot.
+Oil pressure check should be done in ªNeutralº gear
position.
1. Check oil level.
2. Remove oil pressure switch.
3. Install pressure gauge.
4. Start engine and warm it up to normal operating temperature.
5. Check oil pressure with engine running under no-load.
Engine speed
rpmApproximate discharge pressure
kPa (bar, kg/cm2, psi)
Idle speed

4,000More than 147 (1.47, 1.5, 21)
More than 539 (5.39, 5.5, 78)
More than 736 (7.36, 7.5, 107)
If difference is extreme, check oil passage and oil pump.

Body to outer gear axial clearance
V40.050 - 0.105
(0.0020 - 0.0041)
Inner gear to brazed portion of housing
clearance

(0.0018 - 0.0036)
Regulator valve to oil pump cover
clearance
V60.040 - 0.097
(0.0016 - 0.0038)
+If the tip clearance (V2) exceeds the limit, replace gear
set.
+If body to gear clearances (
V1,V3,V4,V5) exceed the
limit, replace oil pump body assembly.
REGULATOR VALVE INSPECTION
1. Visually inspect components for wear and damage.
2. Check oil pressure regulator valve sliding surface and valve
spring.
3. Coat regulator valve with engine oil. Check that it falls
smoothly into the valve hole by its own weight.
If damaged, replace regulator valve set or oil pump cover.
4. Check regulator valve to oil pump cover clearance.
Clearance:
V6: 0.040 - 0.097 mm (0.0016 - 0.0038 in)
