1.7 Reassembling piston and connecting rod
(1)
Apply engine oil to the piston pin, and reassemble the
piston and the connecting rod by inserting the piston
pin, observing the orientation of piston and connecting
rod shown in the illustration.
Note: The pistons and piston pins are assembled to each
other in clearance fit. However, the piston pins are
more easily inserted into the pistons if the pistons are
warmed up with a heater or in hot water.
(2) Using ring pliers, install the snap ring. Check the snap
ring for its tension, and make sure the ring fits snugly in
the groove.
Note: Install all the snap rings so that their end gap faces
toward the bottom of the piston.
