PISTON/CONNECTING ROD
REMOVAL
• Before piston removal, place a clean shop towel
around the connecting rod to prevent damaging the
cylinder sleeve.
• Do not try to remove the piston/connecting rod
assembly from bottom of the cylinder; the assembly
will get stuck in the gap between the cylinder liner
and the upper crankcase.
• Do not interchange the bearing inserts. They must
be installed in their original locations or the correct
bearing oil clearance may not be obtained, resulting
in engine damage.
Remove the following:
