INSPECTION AFTER INSTALLATION
• Before starting engine, check oil/fluid levels incl uding engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-14, "
Fluids and Lubricants".
• Use procedure below to check for fuel leakage.
• Turn ignition switch ON (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leak-
age at connection points.
• Start engine. With engine speed increased, check again for fuel leakage at connection points.
• Run engine to check for unusual noise and vibration.
• Warm up engine thoroughly to make sure there is no leak age of fuel, exhaust gas, or any oils/fluids including
engine oil and engine coolant.
• Bleed air from passages in lines and hoses, such as in cooling system.
• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to spec- ified level, if necessary.

b. Drive out valve guide with a press [under a 20 kN (2 ton, 2.2 US
ton, 2.0 lmp ton) pressure] or a hammer and the valve guide
drift.
WARNING:
Cylinder head contains heat . Wear protective equipment to
avoid getting burned.
INSPECTION AFTER DISASSEMBLY
Valve Dimensions
• Check the dimensions of each valve. For the dimensions, refer to EM-114, "Cylinder Head".
• If dimensions are out of the standard, replace valve and check valve seat contact.
Valve Guide Clearance
Valve Stem Diameter• Measure the diameter of valve stem with micrometer (A).
Valve Guide Inner Diameter• Measure the inner diameter of valve guide with bore gauge.
Valve Guide Clearance
• (Valve guide clearance) = (Valve guide inner diameter) – (Valve stem diameter)
• If the calculated value exceeds the limit, replace valve and/or valve guide.
Valve Seat Contact
• After confirming that the dimensions of valve guides and valves are within the specifications, perform this procedure.
• 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. Refer to EM-76, "
Disassembly and Assembly".

CYLINDER BLOCK
• Measure the outer diameter (Dp) 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 on eachmain 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 lim it, correct or replace crankshaft.
• If corrected, measure the bearing oil clearance of t he 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 t he 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-90, "
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-106, "
Connecting Rod Bearing".

• 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-90, "
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-90, "
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.
• 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.
• If reduction appears in a position other than “d”, regard it as “d”.

• 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 standar ds and the selection method of the
selective fitting parts, follow the procedures.
