The SM 5910 is an industrial-strength, complete Self Starter Motor Assembly specifically engineered for Caterpillar (CAT) 320 series excavators and heavy earthmoving machinery. This ultra-high-output 5KW unit operates on a 24V system and is designed to provide the massive rotational force required to crank large-displacement industrial diesel engines. It is built to survive the extreme vibrations, dust, and temperature fluctuations characteristic of mining and construction sites.
