CRANKSHAFT PIN JOURNAL DIAMETER
 Measure the outer diameter of crankshaft pin journal with a micrometer.
 If out of the standard, measure the connecting rod bearing oil clearance. Then use undersize bearing.
OUT-OF-ROUND AND TAPER OF CRANKSHAFT
 Measure the dimensions at four different points as shown in the
figure on each main journal and pin journal with a micrometer.
 Out-of-round is indicated by the difference in dimensions between
“X” and “Y” at “A” and “B”.
 Taper is indicated by the difference in dimension between “A” and
“B” at “X” and “Y”.
 If the measured value exceeds the limit, correct or replace crankshaft.
 If corrected, measure the bearing oil clearance of the corrected main journal and/or pin journal. Then select
main bearing and/or connecting rod bearing.
CRANKSHAFT RUNOUT
 Place a V-block on a precise flat table to support the journals on
the both end of crankshaft.
 Place a dial indicator (A) straight up on the No. 3 journal.
 While rotating crankshaft, read the movement of the pointer on the
dial indicator. (Total indicator reading)
 If it exceeds the limit, replace crankshaft.
CONNECTING ROD BEARING OIL CLEARANCE
Method by Calculation
 Install connecting rod bearings to connecting rod and cap, and tighten connecting rod bolts to the specified
torque. Refer to EM-101, "
Disassembly and Assembly".
 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 the clearance exceeds the limit, select proper connecting rod
bearing according to connecting rod big end diameter and crank-
shaft pin journal diameter to obtain the specified bearing oil clear-
ance. Refer to EM-117, "
Connecting Rod 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-101, "
Disassembly and Assembly".

 When main bearing cap is removed after being tightened to the
specified torque with main bearings installed, the tip end of bearing
must protrude. Refer to EM-101, "
Disassembly and Assembly".
 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 installed, the
tip end of bearing must protrude. Refer to EM-101, "
Disassembly
and Assembly".
 If the standard is not met, replace connecting rod bearings.
MAIN BEARING CAP BOLT OUTER DIAMETER
 Measure the outer diameters (“d1”, “d2”) at two positions as shown
in the figure.
 If reduction appears in a position other than “d
2 ”, regard it as “d2”.
 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 in the figure.
 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.

DescriptionINFOID:0000000001381436
 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 dimension 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 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 row and column in the “Connecting Rod Bearing Selection
Table”.

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 Bearing 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 main bearing housing inner diameter and crankshaft main
journal diameter individually. Refer to EM-108, "
Inspection".
2. Apply the measured dimension to the “Main Bearing Selection Table”.

4. Heat cylinder head to 110° to 130°C (230° to 266°F) by soaking
in heated oil (A).
5. Press valve guide (1) from camshaft side to dimensions as
shown.
CAUTION:
Cylinder head contains heat, when working, wear protective
equipment to avoid getting burned.
6. Apply reamer finish to valve guide using suitable tool (A).
VALVE SEAT CONTACT
 After confirming that the dimensions of valve guides and valves are within specifications, perform this proce-
dure.
 Apply prussian blue (or white lead) onto contacting surface of valve seat to check the condition of the valve
contact on the surface.
 Check if the contact area band is continuous all around the circum-
ference.
 If not, grind to adjust valve fitting and check again. If the contacting
surface still has NG conditions even after the re-check, replace
valve seat.
VALVE SEAT REPLACEMENT
When valve seat is removed, replace with oversized [0.5 mm (0.020 in)] valve seat.
1. Bore out old seat until it collapses. Boring should not continue beyond the bottom face of the seat recess
in cylinder head. Set the machine depth stop to ensure this. Refer to EM-238, "
Standard and Limit".
