Andrew: Undercarriage refers to the moving (or wearing) parts of a dozer's track system. If you are dealing with a major-brand dozer (Cat, JD, Komatsu, etc.) there are published tables that explain the allowable wear of each component. In most cases, this is much less than the total thickness of the part (example: a pin may be 50% worn with only 10% of its diameter ground off). Warning: while measuring each component and determining the percentage of wear is the best method, many sellers "guesstimate" the wear percentage and use that number in their advertisements. Needless to say, this number is nearly meaningless, and for some strange reason it almost invariably errs on the "optimistic" side. Unless you know the seller to be a person of excellent integrity and mechanical ability, treat any advertised undercarriage wear percentage with a healthy dose of skepticism.
