The specification (SP) value indicates the tolerance of
the value that is displayed in “SPEC” in “DATA MONI-
TOR” mode of CONSULT during normal operation of the Engine Control System. When the value in “SPEC” in
“DATA MONITOR” mode is within the SP value, the E ngine Control System is confirmed OK. When the value
in “SPEC” in “DATA MONITOR” mode is NOT within t he SP value, the Engine Control System may have one
or more malfunctions.
The SP value is used to detect malfunctions that may affect the Engine Control System, but will not illuminate
the MIL.
The SP value will be displayed for the following three items:
• B/FUEL SCHDL (The fuel injection pulse width programmed into ECM prior to any learned on board correc- tion)
• A/F ALPHA-B1/B2 (The mean value of air-fuel ratio feedback correction factor per cycle)
• MAS A/F SE-B1 (The signal voltage of the mass air flow sensor)

CRANKSHAFT RUNOUT
• Place a V-block on a precise flat table to support the journals on
both ends of the crankshaft.
• Place a dial gauge (A) straight up on the No. 3 journal.
• While rotating the crankshaft, read the movement of the pointer on the dial gauge (A), the total indicator runout reading.
OIL CLEARANCE OF CONNECTING ROD BEARING
Method of Measurement
• Install the connecting rod bearings (2) to the connecting rod (3)
and the cap (1), and tighten the c onnecting rod bolts to the speci-
fied torque. Using a inside micrometer measure the inner diameter
of connecting rod bearing (B).
(Oil clearance) = (Inner diameter of connecting rod bearing) –
(Outer diameter of crankshaft pin)
• If clearance cannot be adjusted within the standard, grind crankshaft pin and use undersized bearing. Refer
to EM-105, "How to Select Piston and Bearing"
.
Method of Using Plastigage
• Remove oil and dust on the crankshaft pin and the surfaces of
each bearing completely.
• Cut the Plastigage slightly shorter than the bearing width, and place it in crankshaft axial direction, avoiding oil holes.
• Install the connecting rod bearings to the connecting rod cap, and tighten the connecting rod bolts to the specified torque.
CAUTION:
Do not rotate the crankshaft.
• Remove the connecting rod cap and bearings, and using the scale 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.
OIL CLEARANCE OF MAIN BEARING
Method of Measurement
• Install the main bearings to the cylinder block and bearing cap. Measure the main bearing inner diameter with the bearing cap bolt tightened to the specified torque.
(Oil clearance) = (Inner diameter of main beari ng) – (Outer diameter of crankshaft journal)
• If the measured value exceeds the limit, select main bearings referring to the main bearing inner diameter
and crankshaft journal outer diameter, so that t he oil clearance satisfies the standard. Refer to EM-105,
"How to Select Piston and Bearing".

CYLINDER BLOCK
Method of Using Plastigage
• Remove oil and dust on the crankshaft journal and the surfaces of
each bearing completely.
• Cut the Plastigage slightly shorter than the bearing width, and
place it in crankshaft axial direction, avoiding oil holes.
• Tighten the main bearing bolts to the specified torque. CAUTION:
Do not rotate the crankshaft.
• Remove the bearing cap and bearings, and using the scale 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".
CRUSH HEIGHT OF MAIN BEARING
• When the bearing cap is removed after being tightened to the specified torque with main bearings installed, the tip end of bearing
must protrude.
• If the standard is not met, replace main bearings.
OUTER DIAMETER OF LOWER CYLINDER BLOCK BOLT
• Perform only with M10 (0.39 in) bolts.
• Measure outer diameters (d1, d2) at two positions as shown.
• Measure d2 at a point within area (A) as shown.
• When the value of d1- d2 exceeds the limit (a large difference in dimensions), replace the bolt with a new one.
OUTER DIAMETER OF CONNECTING ROD BOLT
• Measure outer diameter (d) at position as shown.
• When (d) exceeds the limit (when it becomes thinner), replace the
bolt with a new one.
