I have two! hardinge HLV-H lathes. I have had belt slip for a while and have kept adjusting the belt tension on one of them for the last few years.
A few weeks ago one belt snapped.
Nobody here in Australia knows what the nunbers on the belt mean. It has worn narrow because when I brought it over from England the pullys rusted so we cannot match it from actual dimensions. Could any body help me with a part number or size in current use. The old belts are marked Hainsworth P614 S ansdP394 S
