15. Using Piston-Pin Puller (p/n 0644-328), remove
the piston pin. Account for the opposite-side cir-
clip. Remove the piston.
NOTE: It is advisable to remove the oppo-
site-side circlip prior to using the puller.
NOTE: Support the connecting rod with rubber
bands to avoid damaging the rod or install a con-
necting rod holder.
! CAUTION
Do not allow the connecting rod to go down inside
the crankcase. If the rod is down inside the crank-
case and the crankshaft is rotated, severe damage
will result.

with new rings, note the location of each ring for
proper installation. When replacing with new rings,
replace as a complete set only. If the piston rings
must be removed, remove them in this sequence.
