CONNECTING RODS
1. When reinstalling, make sure that cylinder numbers
put on t he connecting rod and cap at disassembly
match. When a new connecting rod is installed, make
sure that the notches for holding the bear ing in place
are on the same side.
2. Replace the connecting rod if it is damaged on the
thrust fa ces at either end. Also if step wear or a
severely rough surface of the inside diameter of the
small end is apparent, the rod must be replaced as
well.
3. Using a connecting rod aligning tool, check the rod for
bend and twist. If the measured value is close to the
repair limit, correct the rod by a press. Any connecting
rod that has been severely bent or distorted should be
replaced.

0.05mm / 100mm (0.0020 in./3.94 in.) or less
