IMPORTANT: It is recommended that the piston and rod assembly be removed from
the crankshaft before removing the piston pin to prevent possible bending of the
connecting rod.
IMPORTANT: It is recommended that new needle bearings be installed in connect-
ing rod to assure lasting repair. If needle bearings must be reused, they should be
reassembled on the same crankpin throw and on the same connecting rod.
