DURABILITY FEATURES Heavy-duty Undercarriage Modular Design Large link, large bushing diameter, and wider sprocket teeth extend undercarriage life. The two-carrier roller design maintains track tension and alignment. One of the design goals behind the creation of the D51 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. Parallel Link Undercarriage System (PLUS) Komatsu’s new Parallel Link Undercarriage System (PLUS) provides less downtime plus longer wear with up to 40%...

MAINTENANCE FEATURES Hydraulically-driven Swing-up Fan Daily Checks The D51-22 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 performed efficiently at ground...
