Caterpillar D4 or D2? clutch disk. Used? shelf worn? I got this with some other Cat parts but can't say for sure it's for a D-4. Should be able to tell by the diameter. It's 14-5/8 inches across the teeth. Two teeth have slight chips from careless handling, but I can't imagine they would effect performance. Very little wear to the surfaces, as seen in the images. $50 plus actual shipping. Western Kentucky. Local pick up would be great.
