CATERPILLAR-C93-C11-C13-BELT-TENSIONER

347-7963 fits Caterpillar's C93, C11 and C13 engines, a spread that covers a large share of Cat's medium-duty industrial applications. As the tensioning arm ages, its spring rate drops and belt slip becomes intermittent before it becomes constant — often first noticed as a squeal on cold starts that fades once the engine warms. Replacing the tensioner resolves this permanently rather than temporarily. Orange.net.za dispatches fast across South Africa.
