CATERPILLAR-C66-C7-C71-PULLEY

This pulley (337-6324) is shared across Caterpillar's C66, C7 and C71 engines, part of the accessory drive system that keeps the belt aligned as it runs between the crank, alternator and other driven components. Misalignment here shows up as premature belt wear on one edge, so a pulley showing wobble or surface scoring should be swapped out rather than run to failure.
