DIFFERENCES FROM FORMER MACHINES

ENGINE POWER TRAIN CONTROL SYSTEM* STEERING SYSTEM*


ENGINE

D5M and D6M are equipped with the Caterpillar 3116 turbocharged engine. In the D5M, the engine is rated at 82 kW (110 flywheel hp). The D6M engine is rated at 104 kW (140 flywheel hp). The 3116 engine has a direct injection fuel system and reduced emissions.

D6R and D7R engines are the same as the former machines...
