Product Description

Caterpillar G399 SI natural gas engine, serial 49C01056, arrangement number 3N3773. The data plate was photographed and is the source for all three numbers. No horsepower or RPM rating is published because the plate photographed carries identification only. The photographs show a V-block gas engine with the cooling group and the flywheel exposed, stored outdoors with surface rust on the exhaust side. Published G399 ratings run from 730 hp (G399 TA) to 930 hp at 1,200 RPM (G399 natural gas) depending on configuration and duty. This unit's rating was not confirmed on the plate photographed, so no output is published here.
