Important Format Explanations
This catalog uses special formats to convey information in illustrations and parts lists. 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
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.
X:Y. X
is the reference number of the service
Reference Numbers with Quantities
Illustrations may have a quantity in parentheses next to a reference number, in the form
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.
X (Y). X
is the reference
