ABSTRACT:
In a two-cycle internal combustion engine (2), the sidefaces (60, 62) of the connecting rod (48) have a polymeric material coating thereon, such as polytetrafluoroethylene, PTFE, providing a bearing between the sidefaces (60, 62) and the crankfaces (38, 40) of the crankarm discs (34, 36) of the crankshaft (24), to prevent galling and eliminate the need to silver plate the sidefaces (60, 62).
