Welcome to Antique Crawler Parts. I specialize in used and reproduction parts for antique crawlers and dozers. Please take a look around to see what I have as well as the services offered. If you see a part for a model here, chances are I am parting out the entire machine. So if you need a part for that same machine but do not see it listed, please contact me. All of our reproduction parts are made out of materials that are the same as or better than the original piece. Everything is machined back to the correct original dimensions. If a piece has been modified or changed to improve upon a known weak spot it will be noted with the item description. Here is a little about myself. I am Chad Enyeart, owner of Antique Crawler Parts, and I have been collecting and restoring antique crawlers since 2000. The family collection is made up of mostly Caterpillar crawlers, but it also has a few John Deere’s, Cletrac’s and Best’s.
