TerryB Posted May 22, 2021 Share Posted May 22, 2021 Has to be a slower operating device as the rpms are in hundreds. At a max of 2400 rpm I would think diesel or some type of equipment. Military is sure possible. 1 1 Link to comment Share on other sites More sharing options...
Dandy Dave Posted May 23, 2021 Share Posted May 23, 2021 Red lined at 1,600. Older diesel or possibly for a generator set or a farm tractor PTO engine speed. Most diesels from the 60's and 70's were governed to run around 1,900 normally and would be run for shot periods at 2,100. 1,600 would be a common engine speed for an output of 540 PTO (Power Take Off) speed for a farm tractor. Also could be for a large marine engine. The bigger they are, The slower they run. Dandy Dave! 1 Link to comment Share on other sites More sharing options...
