If its limit is exceeded, replace thrust bearing with
new standard one or oversize one to obtain standard

Out-of-Round and Taper (Uneven Wear) of Journals
An unevenly worn crankshaft journal shows up as a
difference in diameter at a cross section or along its
length (or both). This difference, if any, is determined by
taking micrometer readings. If any one of journals is
badly damaged or if amount of uneven wear in the sense
exceeds its limit, regrind or replace crankshaft.

Selection of Main Bearings
Standard bearing
If bearing is in malcondition, or bearing clearance is out
of specification, select a new standard bearing according
to the following procedure and install it.
1) First check journal diameter. As shown in the figure, crank web No.2 has stamped numbers.
Three kinds of numbers (“1”, “2” and “3”) represent
the following journal diameters.
Stamped numbers on crank web No.2 represent
journal diameters marked with an arrow in the figure
respectively. For example, stamped number “1”
indicates that corresponding journal diameter is
51.9940 – 52.0000 mm (2.0471 – 2.0472 in.).
Crankshaft journal diameter2) Next, check bearing cap bore diameter without bearing. On mating surface of cylinder block, five
alphabets are stamped as shown in figure.
Three kinds of alphabets (“A”, “B” and “C”) or
numbers (“1”, “2” and “3”) represent the following
cap bore diameters.
Stamped alphabets or numbers on cylinder block
represent bearing cap bore diameter marked with an
arrow in the figure respectively.
For example, stamped “A” or “1” indicates that
corresponding bearing cap bo re diameter is 56.0000
– 56.0060 mm (2.2048 – 2.2049 in.).

CAUTION!
• When servicing the iridium / platinum
spark plugs (slender center electrode type
plugs), do not touch the center electrode
to avoid damage to it. The electrode is not
strong enough against mechanical force
as it is slender and its material is not
mechanically tough.
• Do not clean or adjust gap for the iridium / platinum spark plugs.

Inspect spark plug for:
• Electrode wear
• Carbon deposits
• Insulator damage
If any abnormality is found for nickel spark plugs, adjust
air gap, clean with spark plug cleaner or replace them
with specified new plugs.
For iridium / platinum spark plugs, replace them with
new plugs.
