With the boom in oil and gas production the Caterpillar 3512 series engine has been in increasing demand. The 3512 series engine is not new to the diesel market. It can be found in many different applications such as generators, off-road trucks, boats, and even locomotives. It has been used to power machines in nearly every industrial market. The 3512 has currently found the highest rate of usage in the Gas Compression, Land Drilling, Land Production, Offshore Drilling and Offshore Production industries. The current increase in use can be contributed to the oil and gas booms in both North Dakota and Pennsylvania.

Fuel efficiency has been a hot topic for years, and that hasn’t changed in 2026.

Diesel has dominated heavy-duty trucking for a reason.
It is energy-dense, widely available, familiar to fleets, and supported by a massive fueling and service network. But it is not the only option.
Natural gas semi trucks have been used in commercial fleets for years, especially in refuse, regional haul, port drayage, delivery, and return-to-base operations. They run on either compressed natural gas (CNG), liquefied natural gas (LNG), or renewable natural gas (RNG), offering a lower-emissions alternative to diesel for certain heavy-duty applications.
They are not perfect. They are not a drop-in answer for every fleet. But they are also not experimental.
Natural gas trucks are one of the more mature alternative-fuel options available for heavy-duty commercial transportation today.
HHP Quick Takeaway
Natural gas semi trucks can reduce emissions and fuel-cost volatility in the right application, especially for fleets with predictable routes and access to CNG, LNG, or RNG fueling. The biggest limitations are fueling infrastructure, onboard fuel storage, upfront cost, range planning, and application fit.

Cummins N14 Inframe Rebuild Kit – Additional Items
We’re discussing some inexpensive additional pieces you should think about changing when you rebuild your Cummins N14. The Cummins N14 is a strong, reliable engine that will just keep on going if you treat it right. Depending on how much weight you’re pulling, the average rebuild is needed around 800k to 1 million miles. The standard N14 inframe kit will come with nearly everything you need to rebuild the engine. Here’s a look at some of the additional pieces that are a good idea to change while performing the rebuild. The nice thing is, they won’t break the bank.

In a historic decision by Obama Administration, new fuel efficiency standards for medium and heavy-duty trucks have been passed. These stricter standards, legislation passed as part of President Obamas mounting efforts to combat the effects of climate change, aims to cut fuel consumption and boost fuel efficiency for vehicles weighing 8,500 pounds or more by March 2015. These regulations, to be drafted by the Environmental Protection Agency and the Transportation Department, are then expected to be finalized by March 31, 2016.

Do you like it when your truck breaks down unexpectedly? Probably not. No one does. But what can you do about it? A Preventive Maintenance Inspection (PMI) is a simple way to prevent costly repairs and breakdowns and maximize uptime. Whether you manage an entire fleet of trucks, or if you’re an owner/operator with just one truck, conducting regular inspections is a great, low-cost, high-reward practice. Among other things, PMI can improve your profitability, prevent customer service problems, and, perhaps most importantly, increase safety. There are many things that can cause your engine issues, possibly leading to an overhaul, and regular inspections can help you spot these earlier on.

When a diesel engine suffers a broken crankshaft, it’s easy to assume the crankshaft simply reached the end of its life.
In reality, that’s rarely the full story.
Heavy-duty diesel crankshafts are designed to withstand millions of combustion cycles under enormous loads. Yet even these incredibly strong components are constantly twisting and flexing as each cylinder fires. That twisting motion—known as torsional vibration—is completely normal, but it must be controlled.
That’s where the vibration damper comes in.
While the crankshaft converts combustion into rotational power, the vibration damper absorbs harmful torsional vibrations before they can damage the lower rotating assembly.
When the damper begins to wear out, the crankshaft absorbs more of those forces itself. Over time, the result can be accelerated fatigue, bearing wear, excessive vibration, and eventually a cracked or broken crankshaft.
Understanding how these two components work together can help prevent one of the most expensive diesel engine failures possible.
Quick Takeaway
A broken crankshaft is often the result of long-term torsional fatigue—not simply a defective crankshaft. Replacing both the crankshaft and vibration damper during a major lower-end repair helps restore the engine’s harmonic control system and reduces the risk of repeat failures.
