In order to keep secure position when hoisting engine.
2. Remove engine mounting insulators (RH and LH) under side nut with power tool.
3. Lift with hoist and separate engine and transmission assembly from front suspension member. CAUTION:

Before and during this lifting, always make sure that any harnesses are left connected.

Avoid damage to and oil/grease smearing or spills onto engine mounting insulator.
4. Remove alternator. Refer to SC-20, "
CHARGING SYSTEM" .
5. Remove starter motor. Refer to SC-8, "

9. Remove engine rear member and engine mounting insulator (rear) from transmission.
INSTALLATION
Note the following, and install in the reverse order of removal.

Do not allow engine mounting insulator to be damage and careful no engine oil gets on it.

For a location with a positioning pin, insert it securely into hole of mating part.

For a part with a specified installation orientation, refer to component figure in EM-243, "Removal and
Installation" .

When installing engine mounting brackets (RH and LH) on cylin-
der block, tighten two upper bolts (shown as “A” in the figure)
first. Then tighten two lower bolts (shown as “B” in the figure).
INSPECTION AFTER INSTALLATION
Inspection for Leaks
The followings are procedures for checking fluids leak, lubricates leak and exhaust gases leak.

Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-12, "
RECOMMENDED FLUIDS AND LUBRICANTS" .

Use procedure below to check for fuel leakage.
–Turn ignition switch “ON” (with engine stopped). With fuel pressure applied to fuel piping, check for fuel
leakage at connection points.
–Start engine. With engine speed increased, check again for fuel leakage at connection points.

Run engine to check for unusual noise and vibration.

Warm up engine thoroughly to make sure there is no leakage of fuel, exhaust gases, or any oil/fluids
including engine oil and engine coolant. Slinger bolts:

c. Install main bearings paying attention to the direction.

Main bearing with oil hole and groove goes on cylinder block.
The one without them goes on main bearing cap.

Before installing main bearings, apply engine oil to the bear-
ing surface (inside). Do not apply engine oil to the back sur-
face, but thoroughly clean it.

When installing, align main bearing stopper protrusion to cut-
out of cylinder block and main bearing caps.

Ensure the oil holes on cylinder block and those on the corre-
sponding bearing are aligned.
4. Install pilot converter to crankshaft, if removed.

With drift [outer diameter: approx. 35 mm (1.38 in)], press-fit
as far as it will go.

Press-fit pilot converter with its chamfering side facing crank-
shaft as shown in the figure.

It is possible to remove pilot converter without hoisting engine
with engine stand.
5. Install crankshaft to cylinder block.

While turning crankshaft by hand, make sure it turns smoothly.
6. Install main bearing caps.

Align the identification number to the journal position to install.

Install the upper side of the identification number facing the
front of engine. (The number shall be read correctly from the
rear of engine.)

Using plastic hammer or similar tool, tap them lightly to seat
them on the installation position.
NOTE:
Main bearing cap cannot be replaced as a single parts, because
it is machined together with cylinder block.
