Motor Service Group began as a small but dedicated diesel engine machine shop in Miami in 1949. From the beginning, our focus has been on precision diesel engine machining, accurate inspection, and delivering factory-level results for every customer.
What started as a local operation quickly built a reputation for quality across South Florida. In 1973, we relocated to our current Miami facility to support growing demand for specialized diesel machining services including engine block machining, cylinder head rebuilding, crankshaft grinding, and crack detection.
Over the decades, we expanded our capabilities to serve marine diesel engines, heavy construction equipment, fleet vehicles, power generation systems, and industrial diesel platforms. Our technicians are factory-trained, and our equipment reflects the latest advancements in precision machining and inspection technology.
Today, Motor Service Group serves mechanics, dealerships, marine operators, fleet managers, and industrial clients who require reliable turnaround times and uncompromising quality. Our exchange programs and inspection processes help businesses minimize downtime and keep engines running efficiently.
Motor Service Group has delivered precision diesel engine machining in Miami since 1949. Our facility supports marine engines, construction equipment, fleet vehicles, generators, and industrial diesel platforms with strict quality control and advanced machining equipment.
