Understanding Reference Numbers
Each Identified part in an illustration has a reference
number. The reference number for a part also
appears in the parts list, along with other information
about the part.
This catalog uses two special reference number
formats, one to indicate parts in a service assembly
and another to indicate the quantity of a given part in
an illustration.
Service Assembly Reference Numbers
Parts in service assemblies have reference numbers
in the form a:b. The a represents the reference
number of the entire service assembly and the b
represents 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 illustrations and in part lists.
Reference Numbers Indicating Quantity
In an illustration, if a reference number indicates
more than one part, the reference number has the
form nX y. The n represents the quantity of the part,
the X is the multiplication symbol, and the y
represents the reference number.
For example, in an illustration, the reference number
2X 37 means that two of the parts identified by
reference number 37 are indicated.
