Komatsu D275A-5D Track Frame Outer Guide 17M-30-57131

Komatsu 17M-30-57131 Track Frame Outer Guidance Guard Assembly Optimize the undercarriage track chain alignment and reduce structural rail wear on your heavy earthmoving fleet with the premium replacement 17M-30-57131 outer guidance guard. Engineered to fit the severe-duty track frames of Komatsu crawler dozers, this guidance plate prevents track chain derailment (snaking) and limits lateral impact forces acting on the track rollers, idlers, and sprocket segments during heavy side-slope grading and deep ripping operations. Applicable Machinery Models and Specifications Manufactured to exact original equipment structural tolerances, this guidance assembly fits seamlessly onto the lower undercarriage frame rails, ensuring uniform link contact and maximizing service life: Compatible Crawler Dozers: Komatsu D275A-5, D275A-5D, D275A-5R, D275AX-5, D275AX-5D Bulldozers Undercarriage Classification: Heavy-Duty Track Guide, Outer Frame Wear Plate, Track Roller Guard Engine Configuration Compatibility: Komatsu SAA6D140E-5, SDA6D140E-3 Turbocharged Diesel Engines Technical Specifications and Cross-References This high-tensile guide plate is positioned structurally along the lower track roller frame to shield the roller shells and link chains from direct rock ingress, preventing expensive track link damage.
