From 83 horsepower to 315. Same basic engine design. 🤯

Caterpillar introduced this 5.75-inch bore six-cylinder design in the early 1930s — and variations of it stayed in production all the way to 1981.

Jim Coles explains how an engine configuration that started around 83 HP eventually powered a D8K at 315 HP.

Nearly 50 years of development packed into one basic design.

Why was Caterpillar so hard for its competitors to beat?

Former Cat engineer Jim Coles points to one major advantage: Caterpillar built its own components and engineered them to work together.

Meanwhile, competitors were combining engines, transmissions, axles, hydraulics and other components from multiple manufacturers — and hoping everything played nice.

Ever wonder why an inline-6 can run so much smoother than a 4-cylinder?

Jim Coles explains the engineering behind engine balance — and how Caterpillar overcame the problem with counter-rotating balancers in engines like the D8800 and D339.

Another little piece of engineering that helped make these machines what they were.

“Nobody ran engineering at the level that Caterpillar did.”

Former Caterpillar engineer Jim Coles explains what he believes was the real secret behind Caterpillar’s product design success: vertical integration.

It wasn’t one great engine, transmission, or hydraulic system. It was designing every component to work together as one complete machine.

This was Caterpillar’s engine-design revolution.

Former Caterpillar engineer Jim Coles explains how the new high-BMEP engines combined twin overhead camshafts, four valves per cylinder, turbocharging, aftercooling, and wastegating.

The result? Up to 500 horsepower from a 20-liter engine.

"It was an absolute bet-the-farm decision."

During the Great Depression, Caterpillar made one of the boldest engineering decisions in its history—switching from gasoline to diesel engines. As historian Jim Coles explains, those early engines were engineered so well that many of their core designs remained in service for decades.

Craig needed to restore himself.

Steve wishes he had knocked first. 😂

The commercial is satire. The reminder behind it isn’t: those in the construction industry need time to restore themselves, too.

The Old Iron Candle is our version of self-care—old iron, shop air, and pure nostalgia. Light it, slow down, and take a minute to #RestoreYourself.

Buy a candle or share with someone who needs to restore themself.

At the Earthmoving Legacy Center, we preserve more than historic machines.

We preserve the stories of the people who used them.

As America celebrates its 250th birthday, we wanted to take a moment to honor the generations of builders, operators, mechanics, farmers, soldiers, and innovators whose work helped shape our nation.

These machines are reminders of their legacy.

Happy 250th Birthday, America. Thank you to everyone who helped build this great country.

🇺🇸 If you’re looking for something unique to do this Independence Day, stop by the Earthmoving Legacy Center. We’ll be open July 4 from 9:00 AM–4:00 PM.

Strong teams don’t happen by accident. They’re built intentionally.

The Legacy Leadership Program is designed specifically for the earthmoving and construction industry — focused on practical leadership skills that actually translate to the field, the shop, and the jobsite.

Over two days, participants work through:
• Communication & accountability
• Building trust and team culture
• Leadership under pressure
• Growth mindset & self-awareness
• Coaching, clarity, and connection
• Real-world leadership application

Our May 20–21 class is nearly full, and this is your last chance to reserve a seat before registration closes.

We’ve also opened our next session:
📅 June 23–24

If you or someone on your team is ready to grow as a leader, now’s the time to reach out.

A 100+ year old machine getting ready to breathe again.

This Holt 10-Ton crawler has been in the shop since last summer, and it’s finally starting to look whole again. The engine is coming together, the cab is ready to go back on, and we’re getting close to the moment everyone’s waiting for…

The first fire-up.

When it runs, this tractor will replace another 10-ton currently displayed in the museum.

After more than a century, this piece of earthmoving history is about to move again.

Stay tuned.

🔧 1922 Holt 10-Ton — Transmission Rebuild

This Holt didn’t arrive as a showpiece.
After a fire and decades of wear, it needed a full mechanical restoration before it could ever enter the museum.

In this video, Craig and Steve take on one of the most critical steps — rebuilding and reinstalling the transmission that drives the entire machine.

No shortcuts. Just careful work on a piece of early tracked tractor history.
