Production Highlights

Introduced in the early 1990s, the 3116 engine was part of Caterpillar’s move toward mid-range diesel engines designed for both on- and off-highway applications.

It features a 6-cylinder, 4-stroke diesel engine with a displacement of 6.6 liters, delivering consistent power between 170–300 horsepower, depending on the machine configuration.

The 3116 was one of Caterpillar’s first medium-duty engines to feature direct fuel injection, which improved fuel economy and reduced emissions compared to older models.

Its robust cast-iron block and relatively simple mechanical fuel system made it highly serviceable, especially in field conditions.

Fun Fact: The 3116 engine's design legacy contributed to the development of Caterpillar’s later C-series engines, making it a cornerstone in Cat’s engine evolution.

REBUILD process focus:

Genuine or OEM-grade components for long-term durability.

Precision diagnostics and calibration to match Caterpillar’s strict standards.

Post-rebuild testing under load to ensure peak engine performance and reliability.
