Specifically, one format is used in conjunction with service assemblies and another with quantities associated with reference numbers. Service Assemblies Parts within service assemblies have reference numbers in the form X:Y. X is the reference number of the service assembly and Y is a sequential number unique to each part within the service assembly. For example, a wheel assembly might be identified by reference number 6, the tire by 6:1, the valve by 6:2, and the wheel by 6:3. When you order the assembly identified by reference number 6, you receive all parts identified by reference numbers 6:1, 6:2, and 6:3. However, you may also order any part individually. Reference numbers of this type appear in part lists and as callouts in illustrations. Reference Numbers with Quantities Illustrations may have a quantity in parentheses next to a reference number, in the form X (Y). X is the reference number. Y in parentheses is the quantity of the part identified by the reference number. For example, the illustration callout 4 (2) indicates that two parts are used in that instance. ii
