6.2.11. Connecting rod
1) Distortion
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 small bushing hole
and the connecting rod big end hole.
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 feeler 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.
