Kobelco VI113671-2260 VI113671-2270 Fan Belt Assembly

This cooling fan belt set comprises two V-ribbed belts engineered for the engine accessory drive system on Kobelco compact excavators and wheel loaders. The belts transmit rotational power from the crankshaft pulley to the cooling fan and alternator, maintaining optimal engine operating temperature and electrical system charging. Constructed from high-tensile polyester cord reinforced EPDM rubber compound, the belts resist heat aging, ozone cracking, and abrasion typical in heavy equipment under-hood environments. The precision-molded rib profile ensures consistent wedge grip and reduced slip under high shock loads during hydraulic operation. This set directly replaces Kobelco OEM part numbers VI113671-2260 and VI113671-2270. Compatible with Isuzu 4BG1 and 6BG1 series diesel engines powering the listed machine models.
