Caterpillar Diesel EnginesGenerally, the cranking speed needed to start Caterpillar diesel engines is in the range of 100-120 RPM. When warm, the engines will start at a lower cranking speed. In cold temperatures, battery, starting motor, glow plugs, oil viscosity, starting aids (ether, jacket water heater) and type of fuel used have an effect on how rapidly the engine will start. At all times, the engine must be in good condition to start at the normal cranking speed.
