Engine Parts Manufacturer

Memorial Machine is a trusted engine parts manufacturer that fixes worn engine components for major industrial brands. We rebuild worn engine parts to work like new again. Our facility handles engines from Caterpillar, Cummins, Doosan, Waukesha, and White Superior – basically every major brand running in oil and gas operations today.

Specialized Engine Components Manufacturing

As a leading engine parts and components manufacturer, we understand what each brand builds and how their engines fail. Different manufacturers use unique designs, materials, and tolerances. Our crew knows these differences and rebuilds each brand using the right, specialized methods.

Every manufacturer builds quality engines, but all engines eventually wear out. That’s where we come in as your engine parts manufacturer. Our shop has rebuilt thousands of parts from every major brand since 1974. We know what works and what doesn’t.

Engine Brands We Manufacture Parts For

As an engine parts manufacturer, we rebuild components for all the major brands that power America’s industrial operations. Each manufacturer has its own approach to engine design, but they all require quality rebuilt parts to maintain performance.

Heavy Industrial Engine Parts

These companies build the large engines that power major facilities, compression stations, and industrial plants. Their engines run continuously under heavy loads and need expert remanufacturing to maintain performance.

Mobile and Stationary Engine Components

Some companies make engines for trucks, dozers, and mobile equipment. Others build engines that remain stationary – powering plants, running compressors, generating electricity. Our shop rebuilds parts for engines whether they operate on the highway or in a fixed location for years.

Natural Gas Engine Specialists

Some engine builders focus almost entirely on natural gas applications. They design everything around burning gas fuel – different combustion chambers, special timing, unique fuel systems. We’ve worked on enough of these gas engines to know exactly what makes them tick.

Caterpillar Engine Parts

Caterpillar engine parts power critical operations worldwide. Cat builds tough engines for the harshest conditions – mining, construction, power generation, and industrial applications.

We rebuild Cat parts for 3300, 3500, and 3600 series engines that companies depend on for reliable power. The 3406 and 3412 engines are workhorses in industrial settings. The larger 3516 and 3600 engines power major facilities where downtime costs serious money.

Cat engines are robustly built and respond well to proper rebuilding. We’ve worked on thousands of Cat engines over the decades and know exactly what each model needs. Our rebuilds restore full power and reliability to these proven engines.

Common Cat rebuilds include cylinder heads that crack from heat cycles, engine blocks with worn cylinders, crankshafts that need grinding, and water pumps that develop leaks. We fix all these problems using Cat specifications and quality materials.

Cummins Engine Parts

Cummins engine parts serve industrial and mobile applications where reliability matters most. Cummins builds engines that run for decades with proper maintenance and quality rebuilds.

We specialize in K Model and K19 series engines used in compression, power generation, and industrial equipment. The K19 is legendary for its durability and long service life. These engines power critical operations across America.

Cummins designs are straightforward and service-friendly. Parts are readily available and rebuilds are cost-effective. We keep common Cummins rebuilds in stock for fast delivery when companies need parts quickly.

Typical Cummins rebuilds include cylinder heads with valve problems, engine blocks with cylinder wear, fuel injection components, and cooling system parts. Our shop understands Cummins designs and rebuilds these parts to original specifications.

Doosan Engine Parts

Doosan engine parts power industrial equipment where consistent performance is essential. Doosan builds reliable engines for power generation, industrial machinery, and stationary applications.

We rebuild parts for 11L and 22L series engines that run continuously in demanding environments. These engines are built for long service life but need proper rebuilds to maintain performance over time.

Doosan engines use proven designs with quality materials. They respond well to rebuilding when components wear or fail. Our shop stocks rebuilt parts for common applications and rebuilds cores on an exchange basis.

Common Doosan rebuilds include cylinder heads with cracking or warpage, engine blocks with cylinder wear, turbocharger components, and cooling system parts. We understand these engines and rebuild their components properly.

Waukesha Engine Parts

Waukesha engine parts dominate natural gas applications across America. Waukesha specializes in gas engines and builds some of the most reliable gas-fueled engines in the industry.

We rebuild parts for VHP, 5790, 5792, 5794, 7042, 7044, Series 2, Series 4, Series 5, VRG, and specialty models used in gas compression and power generation. The VHP series engines are legends in the gas industry, with some units running 30+ years.

Waukesha engines are designed specifically for gas fuel, with features like precombustion chambers, special valve timing, and optimized compression ratios. Our shop understands these gas-specific requirements and rebuilds parts accordingly.

Popular Waukesha rebuilds include VHP cylinder heads with prechamber problems, engine blocks with cylinder wear, crankshafts that need grinding, and specialized gas fuel components. We’ve rebuilt thousands of Waukesha parts over the years.

White Superior Engine Parts

White Superior engine parts power heavy-duty industrial applications where reliability and durability are paramount. White Superior builds robust engines for continuous duty in demanding environments.

We rebuild parts for 8G, 8GT, 8GTL, 12G, 12GT, 12GTL, 12SGT, 16G, 16GT, 16GTL, 16SGT, and specialty variants used throughout the oil and gas industry. These engines are built tough for long service life.

White Superior focuses on heavy-duty applications with engines designed for continuous operation under load. Their robust construction makes them excellent candidates for rebuilding when components wear out.

Common White Superior rebuilds include cylinder heads with cracking, engine blocks with cylinder wear, crankshafts requiring grinding, and turbocharger components. Our shop has the equipment and knowledge to handle these large, heavy-duty components.
