The Case G188D engine is a diesel engine that was used in a variety of industrial and agricultural equipment. The engine was manufactured by the Case Corporation, a company that has a long history of producing quality equipment for the agricultural and construction industries.

When the Case G188D engine was first introduced it was a popular choice for use in industrial and agricultural equipment due to its reliability and durability. The engine was a 4-cylinder, inline diesel engine that was designed to be fuel-efficient and powerful. It had a displacement of 3.1 liters and produced approximately 45 horsepower (Mfg rated 48 @ 1900 RPM *(1), or SAE net 43 @ 1900 RPM *(2)). The cylinder bore was 3.812, the crankshaft had a stroke of 4.125" and the piston has a compression ratio of 16.5:1. The engine had an oil capacity of 7 quarts if you include the oil filter (6 quarts without). 

The G188D engine was used in a wide range of equipment including skid steers, backhoes, and excavators. It was also widely used in industrial applications, such as generators and pumps. The engine's compact design, durability, and reliability made it a great choice for use in equipment that required a compact and powerful engine.

One of the key features of the G188D engine was its simplicity. The engine had few moving parts and was relatively easy to maintain, which made it a great choice for use in equipment that was operated in remote locations. The engine also had a high power-to-weight ratio, which made it well suited for use in equipment that required a high level of mobility.

The Case G188D engine was in production for several decades, however, it was phased out as the Case Corporation began to focus on more advanced and modern diesel engines. Today, while the engine is no longer in production, it can still be found in many older pieces of equipment, and it remains a dependable and durable engine.

In conclusion, the Case G188D engine was a diesel engine that was widely used in industrial and agricultural equipment due to its reliability and durability. The engine was a 4-cylinder, inline diesel engine that was designed to be fuel-efficient and powerful. It was used in a wide range of equipment including skid steers, backhoes, and excavators and was also widely used in industrial applications. The G188D engine was phased out as the Case Corporation began to focus on more advanced and modern diesel engines, but it remains a dependable and durable engine that can still be found in many older pieces of equipment.
