OTTO 17M-30-26620 Bushing for Komatsu D275A Bulldozer - the machined steel recoil spring (track tensioner) bushing, supplied as a direct replacement for Komatsu 17M-30-26620 / 17M3026620 and weighing approx. 27.7 kg. It fits in the recoil spring assembly, where it carries the spring rod and pivot under full track tension load, so a worn bush lets the assembly move about and the track will not hold tension. Supplied with the oil hole and oil groove as shown. Check the bore, length and oil hole position against your old bush, or send us your model, serial and a photo, and we will confirm before dispatch. 3-12 months warranty options.
