3.2.11. Connecting rod
1) Distorsion
Check the connecting rod for distortion.
As shown in the figure below, install the
connecting rod to the connecting rod
tester, and check for distortion using a
feeler gauge. If the connecting rod is
found distorted, never re-use it but
replace with a new one.
2) Holes alignment (parallelism)
Measure the alignment of the connecting
rod piston pin bushing holes with con-
necting rod big end holes. At this time
also, use both connecting rod tester and
feeler gauge.
3) Wear
•
Assemble the connecting rod to the
crankshaft and measure connecting
rod big end side clearance using a feel-
er gauge.
•
Assemble the connecting rod to the
piston and measure connecting rod
small end side clearance.
•
If the measured values are beyond the
limit, replace the connecting rod.
