ENGINE / COOLING SYSTEM

                PISTON / CONNECTING ROD ASSEMBLY                                         CAUTION
                1. Lubricate connecting rod small end, piston pin bore    DO NOTapply heat to piston rings or a loss of
                   and piston pin with engine oil.
                                                                                   radial tension could result.
                                   CAUTION
                Do not re-use circlips. Circlips become deformed during
                                the removal process.
                 Do not compress the new clip more than necessary to
                 prevent loss of radial tension. Severe engine damage
                  may result if circlips are re-used or deformed during
                                    installation.
                2. Install a new circlip on one side of piston with gap at
                   the top (12:00 position) or bottom (6:00 position).
                                     NOTE
                           Never re-use a piston pin circlip.

                3. When installing the piston, be sure the piston
                   marking “EX” is positioned towards the exhaust side  5. Install the remaining circlip r with gap at the top
                   of the engine.                                        (12:00 position) or bottom (6:00 position). Push the
                                                                         piston pin in both directions to make sure the clips
                                                                         are properly seated in the groove.


















                4. Place piston q on connecting rod w. Push piston pin
                   e through rod and piston until it seats against the
                   installed circlip.

                                     NOTE
                    Do not tap on pin or cause any sideways force to
                  connecting rod. Warm piston crown with a heat gun if
                   pin cannot be installed by hand, or use a piston pin
                                  installation tool.
