WARNING:
Cylinder head (2) contains h eat. Wear protective equipment
to avoid getting burned.
d. Using suitable tool (A), apply reamer finish to valve guide.
2. Install the valve seat, if necessary. CAUTION:
Replace with oversize [0.5 mm (0.020 in)] valve seat.
a. Ream cylinder head recess diameter (a) for service valve seat.
• Be sure to ream in circles concentric to valve guide center.This will enable valve to fit correctly.
b. Heat cylinder head to 110 to 130 °C (230 to 266 °F) by soaking in
heated oil (A).
c. Provide valve seats cooled well with dry ice. Force fit valve seat into cylinder head. WARNING:
• Cylinder head contains heat. Wear prot ective equipment to avoid getting burned.
• Avoid directly touching cold valve seats. Projection “H”: Refer to

CONNECTING ROD BEARING CRUSH HEIGHT
• When connecting rod bearing cap is removed after being tightened to the specified torque with connecting rod bearings installed, the
tip end of bearing must protrude. Refer to EM-96, " Disassembly
and Assembly " .
• If the standard is not met, replace connecting rod bearings.
MAIN BEARING CAP BOLT OUTER DIAMETER
• Measure the outer diameters (“d 1”, “d 2”) at two positions as shown.
• If reduction appears in a position other than “d 2 ”, regard it as “d 2”.
• If it exceeds the limit (a large difference in dimensions), replace main bearing cap bolt with a new one.
CONNECTING ROD CAP BOLT OUTER DIAMETER
• Measure the outer diameter “d” at position as shown.
• If reduction appears in a position other than “d”, regard it as “d”.
• When “d” falls below the limit (when it becomes thinner), replace connecting rod cap bolt with a new one.
FLYWHEEL DEFLECTION
• Measure the deflection of flywheel contact surface to clutch with a
dial indicator.
• If measured value is out of the standard, replace flywheel. Standard: There must be crush height. PBIC1646E

HOW TO SELECT PISTON AND BEARING
Description INFOID:0000000004784319
• The identification grade stamped on each part is the grade for the dimension measured in new condition.
This grade cannot apply to reused parts.
• For reused or repaired parts, measure the dimens ion accurately. Determine the grade by comparing the
measurement with the values of each selection table.
• For details of the measurement method of each part , the reuse standards and the selection method of the
selective fitting parts, follow the procedures.
Connecting Rod Bearing INFOID:0000000004784320
WHEN NEW CONNECTING ROD AND CRANKSHAFT ARE USED 1. Apply connecting rod big end diameter grade stamped (C) on connecting rod side face to the row in the “Connecting Rod
Bearing Selection Table”.
2. Apply crankshaft pin journal diameter grade stamped (B) on crankshaft front side to the column in the “Connecting Rod Bear-
ing Selection Table”.
3. Read the symbol at the cross point of selected ro w and column in the “Connecting Rod Bearing Selection
Table”.
4. Apply the symbol obtained to the “Connecting Rod Bear ing Grade Table” to select connecting rod bearing.
WHEN CONNECTING ROD AND CRANKSHAFT ARE REUSED 1. Measure the dimensions of the connecting rod big end diameter and crankshaft pin journal diameter indi-
vidually. Refer to EM-103, " Inspection " .

Main Bearing INFOID:0000000004784321
HOW TO SELECT MAIN BEARING
When New Cylinder Block and Crankshaft Are Used
1. “Main Bearing Selection Table” rows correspond to main bearing housing grade on left side of cylinder block.
• If there is a corrected stamp mark (B) on cylinder block, use it as a correct reference.
2. Apply main journal diameter grade stamped on crankshaft front side to column in the “Main Bearing Selection Table”.
3. Read the symbol at the cross point of selected row and column in the “Main Bearing Selection Table”.
4. Apply the symbol obtained to the “Main B earing Grade Table” to select main bearing.
NOTE:
Service part is available as a set of both upper and lower.
When Cylinder Block and Crankshaft Are Reused 1. Measure the dimensions of the cylinder block ma in bearing housing inner diameter and crankshaft main
journal diameter individually. Refer to EM-103, " Inspection " .
2. Apply the measured dimension to t he “Main Bearing Selection Table”.
3. Read the symbol at the cross point of selected row and column in the “Main Bearing Selection Table”.
4. Apply the symbol obtained to the “Main B earing Grade Table” to select main bearing.
