Connecting Rod Twist Inspection
With the big-end arbor [A] still on the V block [C], hold the
connecting rod horizontally and measure the amount that
the arbor [B] varies from being parallel with the surface
plate over a 100 mm (3.94 in.) length of the arbor to de-
termine the amount of connecting rod twist.
If connecting rod twist exceeds the service limit, the con-
necting rod must be replaced.
