3.2.11. Connecting rod
1) Check the connecting rod for distortion.
As shown in the figure right, install the
conn. rod to the conn. rod tester, and
check for distortion using a feeler
gauge. If the conn. rod is found distort-
ed, never re-use it and replace it with a
new one.
2) Measure the alignment of the conn. rod
piston ring bushing holes with conn. rod
big end holes. At this time also, use
both conn. rod tester and feeler gauge.
3) Inspection of the amount of wear on the
conn. rod big end and small end
(1) Assemble the conn. rod to the crank
shaft and measure conn. rod big
end side clearance using a feeler
gauge.
(2) Assemble the conn. rod to the piston
and measure conn. rod small end
side clearance.
(3) If the measured values are beyond
the limit(0.5mm), replace the con-
necting rod.

3.2.12. Tappet
1) Check the tappets for cracks, scores, or
damage.
2) With an outside micrometer, measure
the tappet outside diameter. If the mea-
sured value is beyond the limit, replace
tappets.
