This paper contains the results of experimental analysis of fatigue endurance of used steel teeth regenerated by hard facing. The cylindrical spur gears were tested and compared with the newly made ones, oiler being regenerated by hard facing with subsequent cementation and quenching. The fatigue testing wider variable amplitude loading was used to determine the duration of operational life through measurement of wear. The obtained results demonstrated the impact of hard facing methods on gear endurance in operation. In the test on regenerated gears it was discovered that initial pits appeared almost simultaneously for different facing materials and a bit earlier than in tests on newly made ones, despite their considerably higher pitting rate. Apart from that, the tested operational lives of regenerated and newly-made gears were approximately equal and much longer than predicted.
