 If replacing connecting rod assembly, refer to "CONNECTING
ROD BEARING OIL CLEARANCE" to select the connecting rod
bearing.
Factory installed parts grading: Service parts apply only to grade “0”.

CYLINDER BLOCK DISTORTION
 Using scraper, remove gasket on the cylinder block surface, and also remove engine oil, scale, carbon, orother contamination.
CAUTION:
Be careful not to allow gasket flakes to en ter engine oil or engine coolant passages.
 Measure the distortion on the cylinder block upper face at some different points in six directions with straightedge and feeler gauge.
 If it exceeds the limit, replace cylinder block.
MAIN BEARING HOUSING INNER DIAMETER
 Install main bearing caps and main bearing without installing main bearings, and tighten main bearing cap bolts to the specified
torque. Refer to EM-242, "
Disassembly and Assembly" for the
tightening procedure.
 Measure the inner diameter of main bearing housing with bore gauge.
 If out of the standard, replace cylinder block and main bearing caps as assembly.
NOTE:
Cylinder block cannot be replaced as a single part, because it is
machined together with main bearing caps.

CYLINDER BLOCK
Re-boring Cylinder Bore
1. Cylinder bore size is determined by adding piston to
cylinder bore clearance to piston skirt diameter.
2. Install main bearing caps and main bearing, and tight en to the specified torque. Otherwise, cylinder bores
may be distorted in final assembly.
3. Cut cylinder bores. 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 in diameter 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
 Measure the outer diameter of crankshaft main journals with micrometer.
 If out of the standard, measure t he main bearing oil clearance. Then use undersize bearing. Refer to "MAIN
BEARING OIL CLEARANCE".
CRANKSHAFT PIN JOURNAL DIAMETER
 Measure the outer diameter of crankshaft pin journal with micrometer.
 If out of the standard, measure the connecting rod bearing oil clearance. Then use undersize bearing. Refer to "CONNECTING
ROD BEARING OIL CLEARANCE".
CRANKSHAFT OUT-OF-ROUND AND TAPER
 Measure the dimensions at four different points as shown in thefigure on each main journal and pin journal with micrometer.
 Out-of-round is indicated by the difference in the dimensions between “X” and “Y” at “A” and “B”.
 Taper is indicated by the difference in the dimensions between “A”
and “B” at “X” and “Y”.
 If the measured value exceeds the lim it, correct or replace crankshaft.
Re-bored size calculation: D = A + B – C
where,
D: Bored diameter
A: Piston skirt diameter as measured
B: Piston to cylinder bore clearance (standard value)
C: Honing allowance 0.02 mm (0.0008 in)

 If corrected, measure the bearing oil clearance of the corrected main journal and/or pin journal. Then select
the main bearing and/or connecting rod bearing. Refer to "MAIN BEARING OIL CLEARANCE" and/or
"CONNECTING ROD BEARING OIL CLEARANCE".
CRANKSHAFT RUNOUT
 Place V-block on precise flat table, and support the journals on the both end of crankshaft.
 Place dial indicator straight up on the No. 3 journal.
 While rotating crankshaft, read the movement of the pointer on 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-
242, "Disassembly and Assembly" for the tightening procedure.
 Measure the inner diameter of connecting rod bearing with inside micrometer.
(Bearing oil clearance) = (Connecting rod bearing inner diameter) –
(Crankshaft pin journal diameter)
 If the calculated value exceeds the limit, select proper connecting rod bearing according to connecting rod
big end diameter and crankshaft pin journal diameter to obtain the specified bearing oil clearance. Refer to
EM-250, "
How to Select Piston and Bearing".
Method of Using Plastigage
 Remove oil and dust on crankshaft pin journal and the surfaces of each bearing completely.
 Cut 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-242, "
Disassembly and Assembly" for the tightening procedure.
CAUTION:
Do not rotate crankshaft.
 Remove connecting rod bearing cap and bearing, and using scale
on 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”.

INSPECTION AFTER REMOVAL
Check for deformity, cracks and damage on each parts, replace if necessary.
Ball Joint Inspection
Check for boot breakage, axial looseness, and torque of transverse link and steering outer socket ball joint.
Refer to FSU-13
, PS-17.
INSTALLATION
CAUTION:
Be sure to replace the new differential side oil seal every removal of drive shaft. Refer to FFD-12
.
 Refer to "Removal and Installation"for tightening torque. Install in the reverse order of removal. NOTE:
Refer to component parts location and do not reuse non-reusable parts.
