D31-22 CRAWLER DOZER OPERATOR COMFORT Hydrostatic Transmission (HST) with electronic control Palm command Proportional Pressure Control (PPC) The D31 is equipped with a Komatsu-designed Hydrostatic Transmission (HST), similar to the D51, that allows for Quick-Shift (3 speed) or variable (20 speed) selection. The HST consists of dual-path closed-circuits with two variable displacement piston pumps and two variable displacement travel motors. Hydrostatic steering eliminates steering clutches and brakes, providing smooth powerful turns. Fully electronic control provides automatic shifting and...

C R AW L E R D O Z E R D31-22 DURABILITY FEATURES Heavy-duty undercarriage Modular design Large links, large bushing diameters, and wide sprocket teeth extend undercarriage life. Just like the D51, one of the design goals behind the creation of the D31 was to manufacture a more durable machine. This was achieved by reducing component complexity and using a strong modular design for increased serviceability and durability. Durable and reliable main frame Komatsu welds the track frames to the main frame with large connecting bars and weldments, providing the ideal stiffness required in a...

C R AW L E R D O Z E R D31-22 MAINTENANCE FEATURES Hydraulically-driven swing-up fan Daily checks The D31-22 utilizes a swing-up fan with a gas strut-assisted lift locking system to provide easy access to the (side-byside) radiator, oil cooler, and charge air cooler. The swing-up feature makes it easier to access cooling cores. The hydraulic fan has a “cleaning” mode. The fan rotates in the reverse direction and helps to clear off objects in front of the cooling areas. The fan is protected by thick steel louvers and an additional fan screen for added durability. All daily checks can be...
