New Holland D180 Crawler Dozer WorShop Service Manual

In the Power Steering version a hydraulic powered motor is actuating epicycloidal reduction gears that replace the steering clutches. The reduction gears on both sides generate different speeds in the output gear of each track, to enable machine
turning. At any time during a turn 100% of the engine power is transmitted to the tracks enabling smooth and powerful turns. Possible counter – rotation minimises the turning radius. Excellent manoeuvrability and Shock-free steering minimises operator fatigue and reduces machine down time. Some design decisions made during product development have boosted the D180 pushability and levelling performance.
– The centre of gravity at only 78 cm height from the ground and 157 cm from the sprocket axis
ensures outstanding stability.
– Push beam to undercarriage and undercarriage to frame hinging are differentiated to guarantee optimum balance between machine weight and beam push. This prevents the undercarriage front from sinking into the ground, as would occur with coincident fulcrums, and the tendency to lift, which would happen if they were too far apart.
