Key considerations before purchasing industrial engines

Buying an industrial engine is a significant investment that demands careful attention to detail. With so many technical factors involved, the process can seem daunting, but it doesn’t have to be. This guide outlines the essential aspects you should consider when selecting an industrial engine, helping you make a well-informed decision.

Choosing the Right Industrial Engine for Your Application

The type of engine you need depends on its intended application. Industrial engines come in various forms, each with specific requirements for power, efficiency, and fuel type. These engines drive a wide array of machinery across industries such as construction, agriculture, manufacturing, transportation, power generation, and marine operations. Understanding the distinct characteristics of engines used in these fields is crucial.

For instance, a marine engine must be corrosion-resistant and feature specialized cooling systems, while engines for construction or manufacturing may prioritize power output and durability. Two primary factors to consider when choosing an engine are its size and fuel type:

  • Size: The engine’s size determines its power output. Evaluate the machinery it will power and calculate the necessary power to ensure the engine meets, but does not exceed, those requirements.
  • Fuel Type: The choice of fuel—whether diesel, gasoline, natural gas, or electric—affects operating costs and environmental impact. Diesel engines are common for heavy-duty tasks, but other fuels may offer specific advantages depending on availability, cost, and environmental considerations.

New vs. Used (industrial) Engine

Deciding between a new or used engine is another important step in the buying process. Used engines generally come at a lower cost and may have a proven performance history, making them easier to assess. They are often customizable to meet specific power or size needs and are usually more readily available.

However, when purchasing a used engine, it’s vital to examine maintenance records and usage history to gauge reliability. Ensure the seller has a reliable process for testing and quality assurance, as these factors significantly impact the engine’s suitability for your needs.

Leading Industrial Engine Brands

Choosing a reputable brand can provide confidence in your purchase. Top brands known for their reliability in various industrial applications include:

  • Cummins: Renowned for durability, serving diverse industries including marine.
  • Caterpillar: Specializes in construction and industrial engines, offering diesel, natural gas, and marine options.
  • Kohler: Offers a wide range of diesel, gas, and marine engines with a long-standing reputation.
  • MTU: A global leader in power generation, particularly with diesel and marine propulsion systems.

Diesel Engine Cylinder Head Buying Guide | Diesel Pro Power

The diesel cylinder head in your engine probably doesn’t get a lot of attention until you notice a problem with your boat’s performance. Without cylinder heads, there’d be no pressure seal within engine cylinders or the internal combustion that powers modern engines.

Additional responsibilities of diesel engine cylinder heads include:

  1. Provides a housing at the top of the engine block for the combustion chamber, exhaust valves, lifters and springs.
  2. Lets air into the combustion process and evacuates exhaust.
  3. Helps fuel and coolant move through the marine engine smoothly.

When it’s time to replace your marine engine’s cylinder heads, refer to our buying guide. Learn more about the signs that your cylinder head needs to be replaced and find suggestions for what to look for in a new or remanufactured diesel cylinder head.

Signs You Need to Replace Your Boat’s Diesel Cylinder Head

Look for these five signs that your engine cylinder head may be reaching the end of its lifecycle:

1. Your boat is consuming more oil than it should.

2. If your cylinder head is cracked, the engine may issue white smoke. This signifies potential oil contamination.

3. Your boat is leaking oil or coolant.

4. If the pressure seal of a cylinder head is compromised, each stroke of the engine will be weaker than it should be, limiting the total power output of your boat.

5. If the cylinder head is worn or cracked, your engine may misfire. When this occurs, it forces the contents of the cylinder through the rest of the engine system components.

Tips When Buying Diesel Engine Cylinder Heads for Your Boat

When choosing between a OEM engine cylinder head or a remanufactured one, here’s what to keep in mind:

Remanufactured cylinder heads:

 To save money, aftermarket engine cylinder heads are an ideal choice. Only buy rebuilt engine cylinder heads from a source with a solid reputation, like Diesel Pro Power.

New cylinder heads:

Here are a few additional buying tips for diesel cylinder heads to ensure you get the results you’re looking for:

Match the cylinder head with your engine:

Not every cylinder head is compatible with all marine engines. Make sure you know your transmission and engine model numbers. If you’re not sure, get help from your mechanic.

Match the material to the engine block:

If you’re stuck between a cast iron or aluminum cylinder head and don’t know which to choose, match the build material of your replacement part with the primary engine block material.

Look for a good warranty:

 Even rebuilt engine parts from reputable dealers will carry some kind of warranty. Make sure your provider’s policies meet your expectations.
