CATERPILLAR-IDLER-PULLEY

133-7023 is a Caterpillar idler pulley, the non-driven wheel that keeps the accessory belt properly routed and tensioned as it passes between the crank pulley and driven components. These run a sealed bearing internally, so there's no service interval short of full replacement once the bearing develops play or noise. Left running, a failing idler can shed the belt entirely at the worst possible moment. Orange.net.za delivers this part fast, anywhere in South Africa.
