PISTON AND CONNECTING ROD DISASSEMBLE
IMPORTANT: Prior to piston/connecting rod removal, mark or identify the piston/connecting rod assembly, and its orientation to the front of the
engine, before removal.
1. Remove the pistons from the engine following the instructions found in the Engine Repair Section of the Service Manual.
NOTICE: A rod kiln MUST be used during assembly of the connecting rod to the piston. If a connecting rod kiln is not available, seek the assistance
of a reputable machine shop with a kiln. Under NO circumstances should an acetylene torch or other uncontrolled heating device be used on
connecting rods, as permanent damage to the connecting rod may result.
IMPORTANT: It is not necessary to replace the piston rings, unless they were damaged during the repair process. If the piston rings are to be
reused, mark or identify the location/order of the rings as they correspond to location on the piston being serviced.
2. Using piston ring pliers, remove the piston rings from the piston.
