Engine
The Cat 3306B is a proven engine that delivers reliability and durability. The efficient and powerful engine delivers maximum loading and tramming performance in the most demanding mining applications. Complete system integration of the engine and transmission ensures fuel efficiency and smooth operation.
High Torque Rise
Provides unequalled lugging force while digging, tramming and traversing steep grades. Torque rise effectively matches transmission shift points for maximum efficiency and fast cycle times.
Radiator
Modular radiator with swing-out grill provides easy access for cleaning or repair. Built in sight gauge allows for quick, safe coolant level checks.
Pistons
Oil cooled pistons increase heat dissipation and promote longer piston life.
Full-length Water-cooler
Full-length water-cooled cylinder liners provide maximum heat transfer.
Turbocharged and Aftercooled
Jacket water aftercooling provides improved fuel economy by packing cooler, denser air into cylinders for more complete combustion of fuel and lower emissions. The turbocharger enhances performance and efficiency.
Fuel Injection
The high pressure direct injection fuel system provides excellent fuel atomization for unmatched reliability and durability.
Crankshaft
The crankshaft is forged and induction hardened for long‑term durability.
