• When installation directions are specified, install parts according to the directions. Refer to EM-72, "Compo-
nent".
• Prior to installing the upper torque rod, apply a light coat of silicone
lubricant (A) to the washer facing side of the bushing inner tube as
shown.
NOTE:
• Apply silicone lubricant (A) by dabbing the outward facing tube
surface with a sponge or suitable tool.
• Do not apply excess lubricant.
• Make sure that each mounting insulator is seated properly, and tighten nuts and bolts.
• Tighten engine mounting insulator (RH) bolts in the numerical
order shown.
INSPECTION AFTER INSTALLATION
Inspection for Leaks
The following 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-10
.
• 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 leak-
age 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 includ-
ing engine oil and engine coolant.
• Bleed air from lines and hoses of applicable lines, such as in cooling system.
• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to the
specified level, if necessary.

• Install connecting rod bearings (2) to connecting rod (3) and con-
necting rod bearing cap (1), and tighten connecting rod bolts to the
specified torque. Refer to EM-77, "
Disassembly and Assembly"
for tightening procedure.
• Measure the inner diameter of connecting rod bearing with an
inside micrometer.
(Bearing oil clearance) = (Connecting rod bearing inner diameter)
– (Crankshaft pin journal diameter)
• If clearance exceeds the limit, select proper connecting rod bearing according to connecting rod big end
diameter and crankshaft pin journal diameter to obtain specified bearing oil clearance. Refer to EM-85, "
How
to Select Piston and Bearing".
Method of Using Plastigage
• Remove engine oil and dust on crankshaft pin and the surfaces of each bearing completely.
• Cut a plastigage slightly shorter than the bearing width, and place it in crankshaft axial direction, avoiding oil
holes.
• Install connecting rod bearings to connecting rod and cap, and tighten connecting rod bolts to the specified
torque. Refer to EM-77, "
Disassembly and Assembly" for the tightening procedure.
CAUTION:
Never rotate crankshaft.
• Remove connecting rod cap and bearing, and using the scale (A)
on the plastigage bag, measure the plastigage width.
NOTE:
The procedure when the measured value exceeds the limit is
same as that described in the “Method by Calculation”.
MAIN BEARING OIL CLEARANCE
Method by Calculation
• Install main bearings (3) to cylinder block (1) and main bearing cap
(2), and tighten main bearing cap bolts to the specified torque.
Refer to EM-77, "
Disassembly and Assembly" for the tightening
procedure.
• Measure the inner diameter of main bearing with a bore gauge.
(Bearing oil clearance) = (Main bearing inner diameter) – (Crank-
shaft main journal diameter)

MAIN BEARING CRUSH HEIGHT
• When main bearing cap is removed after being tightened to the
specified torque with main bearings (1) installed, the tip end of
bearing must protrude (B). Refer to EM-77, "
Disassembly and
Assembly" for the tightening procedure.
• If the standard is not met, replace main bearings.
CONNECTING ROD BEARING CRUSH HEIGHT
• When connecting rod bearing cap is removed after being tightened
to the specified torque with connecting rod bearings (1) installed,
the tip end of bearing must protrude. Refer to EM-77, "
