Standard features built into the new D11 offer improved access to the operator compartment. Service technicians can also fill the Auto Lube system and change the coolant and hydraulic, engine and powertrain oil from the ground. The ground-level electrical centre provides convenient access to the lockout control, engine shutdown switch, and switches for access ladder raise/lower and remote control mode options. Improved service, operation and safetyĪ 30% larger engine oil sump capacity extends preventive maintenance intervals to 500 hours in challenging environments, giving customers more uptime. Improved reversing fan function delivers greater reverse airflow for radiator cleanout. A new single-plane cooling system design better dissipates heat to maintain consistent operating temperatures, even in extreme heat, and it provides easier core cleanout. ![]() Replaceable bearings on the ripper and blade pin boreholes and new push arm trunnion bearing inserts offer fast replacement and extend component life.Īvailable with a choice of emissions solutions to meet regional requirements, the Cat C32 engine delivers power ratings of 634 kW (850 hp) forward and 712 kW (955 hp) reverse for increased performance. The new D11 also improves on the time-tested elevated sprocket undercarriage with a more robust track roller frame to extend component service life. For example, the larger equaliser bar features an improved bearing design to increase reliability. Redesigned structures and components increase reliability and durability for higher utilisation. When combined with the new, high horsepower reverse function, the machine delivers 4 - 8% greater productivity while burning less fuel. The new stator clutch torque divider provides improved drive train efficiency. The variable hydraulic pumps adjust output to meet demand, which saves energy, reduces heat generation and extends component life. New load-sensing hydraulics and new drive train components deliver up to 8% fuel efficiency gains. Time-saving service updates reduce daily maintenance and boost machine uptime. Engineered to be rebuilt multiple times, the new D11 has a redesigned main frame that delivers lower total cost of ownership over the life of the machine. The new Cat® D11 Dozer features new load-sensing hydraulics and high horsepower reverse combined with the latest technology to move more material at a lower cost per tonne.
