Why Remanufactured for Industrial Applications?
Significant Cost Savings
Industrial diesel engines are expensive — a new CAT C18 can cost $473,000+. Our remanufactured units deliver the same performance at 40–60% less, freeing capital for other operational needs.
Faster Availability
New industrial engines can have lead times of 6–12 months. Our remanufactured engines typically ship within 3–5 business days, minimizing equipment downtime.
OEM-Quality Warranty
Every remanufactured engine comes with our comprehensive warranty. For generator and critical applications, extended warranty options are available.
Environmental Responsibility
Remanufacturing an engine uses 85% less energy than manufacturing a new one. It's the sustainable choice for environmentally conscious operations.
Industrial Engine FAQ
How much does a remanufactured industrial diesel engine cost?
Remanufactured industrial diesel engines range from $4,000 to $30,000+ depending on the make, model, and horsepower. Smaller engines like the Perkins 1104 start around $4,000, mid-range engines like the Cummins QSL 9 run $6,500–$11,000, and large engines like the Cummins KTA 38 can reach $30,000. Call (631) 991-7700 for an exact quote.
Can I use a truck engine in an industrial or generator application?
Many industrial engines share the same base block as their on-highway counterparts but have different accessories, governor settings, and cooling configurations. For example, a Cummins QSX 15 shares its architecture with the ISX but has industrial-rated accessories. We can supply engines configured for your specific industrial application.
What is the difference between standby and prime power generator engines?
Standby generators run only during power outages (typically less than 200 hours/year) and can be rated at higher output. Prime power generators run continuously as the primary power source and are rated at a lower, sustainable output. The engine configuration, governor settings, and cooling capacity differ between the two ratings.
How long does a remanufactured generator engine last?
A properly maintained remanufactured generator engine can last 20,000 to 40,000+ operating hours in standby applications and 10,000 to 20,000 hours in prime/continuous applications. Regular oil changes, coolant maintenance, and load bank testing are essential for maximizing engine life in generator applications.
Do you offer engines for specific generator brands like Caterpillar, Cummins, or Kohler?
Yes, we supply remanufactured engines compatible with all major generator brands including Caterpillar, Cummins Power Generation (Onan), Kohler, Generac, MTU, and others. The key is matching the engine model, horsepower rating, and accessory configuration to your specific generator set.
Can you help me identify the right engine for my industrial equipment?
Absolutely. Our industrial engine specialists can help identify the correct replacement engine based on your equipment make/model, the engine serial number, or your application requirements. Call (631) 991-7700 with your equipment details and we'll find the right engine.
