5. Cylinder bore size is determined by adding pi
ston-to-bore clearance to piston diameter (A).
6. Install main bearing caps, and tighten to the specified torque. Otherwise, cylinder bores may be distorted after boring.
7. Cut cylinder bores. •When any cylinder needs boring, all ot her cylinders must also be bored.
• Do not cut too much out of cylinder bore at a time. Cut only 0.05 mm (0.0020 in) or so in diameter
at a time.
8. Hone cylinders to obtain specified piston-to-bore clearance.
9. Measure finished cylinder bore for out-of-round and taper. •Measurement should be done after cylinder bore cools down.
CRANKSHAFT
1. Check the crankshaft main and pin journals for scoring, wear, or
cracks.
2. Measure the journals for taper and out-of-round.
3. Measure crankshaft runout.
a. Place a V-block on a precise flat table to support the journals on the both ends of the crankshaft.
b. Place a dial gauge straight up on the No. 3 journal.
c. While rotating the crankshaft, read the movement of the pointer on the dial gauge.
BEARING CLEARANCE
• Use either of the following two methods, however me thod (A) gives more reliable results and so is the pre-
ferred method.
Method A (Using Bore Gauge and Micrometer )

1. Set the main bearings in their proper positions on the cylinder
block and the main bearing cap.
2. Install the main bearing caps and bearing beam to the cylinder block. Tighten all bolts in the numerical order as specified. Refer
to EM-224, "Disassembly and Assembly"
.
3. Measure the inner diameters (A) of each main bearing as shown.
4. Measure the outer diameters (Dm) of each crankshaft main jour- nal as shown.
5. Calculate the main bearing clearance. Main bearing clearance = (A) - (Dm)
• If it exceeds the limit, replace the bearing.
• If clearance cannot be adjusted using any standard bearing
grade, grind crankshaft journal and use an undersized bear-
ing.
• When grinding the crankshaft journal, confirm that the (L) dimension in the fillet role is more than the specified limit.
6. If the crankshaft or the cylinder block is replaced wit h a new one, select thickness of the main bearings as
follows:
SEM175F
SEM845E
Standard : 0.035 - 0.045 mm (0.0014 - 0.0018 in)
Limit : 0.065 mm (0.0026 in)

a. The grade number of each cylinder block main journal is
punched on the respective cylinder block. These numbers are
punched in either Arabic or Roman numerals. If measured diam-
eter is out of the grade punched, decide suitable grade from
available main bearings.
b. The grade number of each crankshaft main journal is punched on the crankshaft end. These numbers are punched in either
Arabic or Roman numerals. If measured diameter is out of grade
punched, decide the suitable grade from available main bear-
ings.
c. Select the main bearing suitable thickness according to the following table:

Connecting Rod Bearing (Big End)
1. Install the connecting rod bearing to the connecting rod and cap.
2. Install the connecting rod cap to the connecti ng rod. Tighten to specification. Refer to EM-224, "Disassem-
bly and Assembly".
3. Measure the inner diameter (C) of each connecting rod (big end) as shown.
4. Measure the outer diameter (Dp) of each crankshaft pin journal.
5. Calculate the connecting rod bearing clearance. Connecting rod bearing clearance = (C) - (Dp)
6. If the calculated clearance exceeds the specified limit, replace the bearings.
7. If the clearance cannot be adjusted within the standard of any bearing, grind the crankshaft journal and use undersized bear-
ings.
8. If the crankshaft is replaced with a new one, select the connect-
ing rod bearings according to the following table:
Connecting Rod Bearing Grad e Number (Identification
Color)
These numbers are punched in eit her Arabic or Roman numer-
als.
Method B (Using Plastigage)
• Remove oil and dust on the 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 the connecting rod bearings to the connecting rod cap, and tighten the connecting rod nuts 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 repair limit
is same as that described in "Method A (Using Bore Gauge and Micrometer)".

2. Remove the drive plate.
• Loosen the drive plate bolts in a diagonal order.
CAUTION:
• Do not disassemble drive plate.
• Do not place drive plate with signal plate facing down.
• When handling the signal plate, take care not to damage
or scratch it.
• Handle the signal plate in a manner that prevents it from becoming magnetized.
INSTALLATION
Installation is in the reverse order of removal.
• When installing the drive plate to the crankshaft, use the triangle shaped match mark (A) as shown to correctly align the crankshaft
side dowel pin to the drive plate side dowel pin hole.
• Install the drive plate and drive plate reinforcement plate in the direction as shown.
• Tighten the drive plate bolts in a diagonal pattern in two steps. Refer to EM-224, "Disassembly and Assembly"
.
