CATERPILLAR-V-BELT

6L6557 is another of Caterpillar's legacy-format part references, fitted to older engine platforms still running in South African fleets. Belts on these older engines are usually a standard V-profile rather than the ribbed designs common on newer Cat engines, and correct length matters more than usual since older tensioning systems tend to have a narrower adjustment range. Orange.net.za ships this part fast across South Africa.
