Its in-line 4-cylinder design has a compact footprint for easy installation. Ratings range from 60-85 hp, with both naturally aspirated and turbocharged versions that deliver strong performance. Single-sided maintenance is just one of many standard features and options that let you customize your B3.3.

Getting the right combination to match your equipment, operating environment and workloads has never been easier. Cummins Advisor is ready to provide expert assistance with your installation process.

Every B3.3 engine is covered by Cummins three-step warranty, one of the most comprehensive and simple plans in the industry.

Cummins B3.3 engines meet all current Tier 2/Stage II standards and achieve Tier 3/Stage IIIA and Tier 4 Interim/Stage IIIB compliance with in-cylinder technology that maintains a compact, simple and cost-effective design solution and fits the exact same footprint as today.

With every start on every piece of equipment, Cummins B3.3 is setting records for dependable performance. Its simple compact design makes it one of the most reliable engines in Cummins entire lineup of off-highway engines. With or without turbocharging, it has a low heat rejection rate.

The B3.3 is built to last, with a cast-iron parent bore block designed for durability and reliability. Every element of the design adds value to the customer, including:

Direct injection for increased fuel efficiency, low heat rejection and quicker starts
A deep, stiff crankcase with structural ribs for lower noise and increased life
An isolated valve cover for reduced noise
Optional intake air heater for cold-weather starting
Low rotating inertia (30% less than industry average) for reduced vibration
Left- or right-side service options for easy maintenance
SAE "A" PTO mounting option with engine-mounted, gear-driven designs (Front-mounted crank PTO generates 100% torque for hydraulic applications)

Maintenance Intervals

Turbocharged B3.3 engines require an oil change at 350-hour/3-month intervals, while naturally aspirated models can go 500 hours or 6 months between oil changes.
