4.7 Inspecting connecting rod bend and twist
(1)
Measure the dimensions of C and L in the illustration to
check bend and twist of the connecting rod. Straighten
the connecting rod with a press to meet the standard.
If the standard is exceeded after correction, replace the
connecting rod with a new one.
(2) In general, a connecting rod aligner is used to check
bend and twist.
Note: Before checking bend, tighten the connecting rod cap
to the specified torque.
(3) To inspect the connecting rod with the piston installed,
turn the piston upside down and place it on a surface
plate. Insert a round bar having the same diameter as
the crankpin into the big-end bore, and measure the
height of the bar using a dial gauge.
