CAMSHAFT

Camshaft Journal Oil Clearance
CAMSHAFT JOURNAL DIAMETER

Measure outer diameter of camshaft journal with micrometer.
CAMSHAFT BRACKET INNER DIAMETER

Install camshaft bracket and tighten bolts to the specified torque. Refer to EM-184, "INSTALLATION" for
the tightening procedure.

Measure inner diameter of camshaft bracket using the inside
micrometer.
CAMSHAFT OIL CLEARANCE CALCULATIONS

(Oil clearance) = (Camshaft bracket inner diameter) – (Camshaft journal diameter)

If out of standard, refer to the standard value of each unit, then replace the camshaft and/or cylinder head.
NOTE:
As the camshaft bracket is manufactured with the cylinder head, it is impossible to replace only the cam-
shaft bracket.
Camshaft End Play

7. Install main bearing caps.

Identify main bearing caps by the punched mark. Install cor-
rectly matching the journal No. on the bearing cap and the
journal with the front mark facing forward.

Main bearing caps are commonly processed with the cylinder
block. Therefore, caps and cylinder block should be replaced
as a set.
8. Check the main bearing cap bolts for deformation. Refer to EM-254, "
MAIN BEARING CAP BOLT
DEFORMATION" .
9. With the TORX socket (size: E14, commercial service tool),
tighten the main bearing cap bolts according to the following
procedure:
a. Apply engine oil to the threaded part and seat surface of each
bolt.
b. Tighten all bolts in numerical order shown in the figure.
c. Put alignment marks (with paint) on each bolt and the main
bearing cap, all in the same direction. (When using a protractor)
d. Then, tighten 90 degrees. (angle tightening)
CAUTION:
Always use either the angle wrench (special service tool) or
protractor during angle tightening. Avoid tightening based
on visual checks alone.

After tightening bolts to specified torque, make sure that
crankshaft rotates smoothly.

Check crankshaft end play. Refer to EM-245, "CRANKSHAFT
END PLAY" .
10. Check the outer diameter of connecting rod bolts. Refer to EM-
254, "CONNECTING ROD BOLT DEFORMATION" .
11. Install piston to connecting rod.
a. Using the snap ring pliers, install snap rings to groove on piston rear side.

Fit snap ring correctly into grooves.
b. Install pistons to connecting rods.

Using the industrial use dryer, heat pistons up to approx. 60 to
70°C (140 to 158°F) until piston pin can be pressed down by
finger touch. Then insert piston pin into piston and connecting
rod from front side of piston toward rear.

If it exceeds the limit, replace connecting rod and/or piston and piston pin assembly. Refer to EM-242,
"HOW TO SELECT CONNECTING ROD BEARING" and/or EM-242, "HOW TO SELECT PISTON" .
CYLINDER BLOCK TOP SURFACE DISTORTION

Using scraper, remove gasket installed onto cylinder block sur-
face. Remove contamination such as engine oil, scale, and car-
bon.
CAUTION:
Keep broken pieces of gasket clear of engine oil and engine
coolant passages.

Use straightedge and feeler gauge to check block upper surface
for six distortion.

If it exceeds the limit, replace cylinder block.
MAIN BEARING HOUSING INNER DIAMETER

Without installing main bearings, install main bearing caps, and
tighten bolts to the specified torque. Refer to EM-235, "
ASSEM-
BLY" .

Measure the inner diameter of main bearing housing with a bore
gauge.

If the measurement is out of the standard, replace cylinder block
and main bearing caps.

2. Install main bearing caps and tighten bolts to the specified torque. Refer to EM-235, "ASSEMBLY" . This
will prevent distortion of cylinder bores.
3. Cut cylinder bore.
NOTE:

When any cylinder needs boring, all other 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 at a time.
4. Hone cylinders to obtain the specified piston-to-cylinder bore clearance.
5. Measure finished cylinder bore for the out-of-round and taper.
NOTE:

Measurement should be done after cylinder bore cools down.
CRANKSHAFT MAIN JOURNAL DIAMETER

Use micrometer to measure main journal diameter.

If out of the standard, measure the main bearing oil clearance.
then use the undersize bearing. Refer to EM-253, "
MAIN BEAR-
ING OIL CLEARANCE" .
CRANKSHAFT PIN JOURNAL DIAMETER

Use micrometer to measure crankshaft pin journal diameter.

If out of the standard, measure the connecting rod bearing oil
clearance. then use the undersize bearing. Refer to EM-252,
"CONNECTING ROD BEARING OIL CLEARANCE" .
CRANKSHAFT OUT-OF-ROUND AND TAPER

Using micrometer, measure each main journal and pin journal at
four points shown in the figure.

Out-of-round value is indicated by difference in dimensions
between directions “X” and “Y” at points “A” and “B”.

Taper value is indicated by difference in dimensions between
points “A” and “B” in directions“X” and“Y”.D: Bored diameter

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 the main bearing or connecting rod bearing. Refer to EM-253, "
MAIN BEARING OIL CLEARANCE"
and/or EM-252, "CONNECTING ROD BEARING OIL CLEARANCE" .
CRANKSHAFT RUNOUT

Place V-block onto surface plate to support main journal at both
ends of crankshaft.

Position dial indicator vertically onto No. 3 journal.

Rotate crankshaft to read needle movement on dial indicator
(total indicator reading).

If it exceeds the limit, replace crankshaft.
CONNECTING ROD BEARING OIL CLEARANCE
Method by Measurement

Install connecting rod bearings to connecting rod and cap, and
tighten connecting nuts to the specified torque. Refer to EM-235,
"ASSEMBLY" . Use inside micrometer to measure connecting
rod bearing inner diameter.
(Bearing oil clearance) = (Connecting rod bearing inner diame-
ter) − (Crankshaft pin journal diameter)

If clearance exceeds the standard, 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-242, "
HOW TO SELECT CONNECTING
ROD BEARING" .
Method of Using Plastigage

Remove contamination such as engine oil, dust completely from
crankshaft pin journal and each bearing surface.

Cut plastigage slightly shorter than bearing width, place it in
crankshaft direction, avoiding oil holes.

Install connecting rod bearings to caps, and tighten connecting
rod nuts to the specified torque. Refer to EM-235, "
ASSEMBLY"
for the tightening procedure.
CAUTION:
Do not rotate crankshaft.

Remove connecting rod caps and bearings, and measure plasti-
gage width using scale on plastigage bag.
NOTE:
If out of specification, take same action mentioned in “Method by Measurement”.Standard : 0.05 mm (0.0020 in)
