Ordering Replacement Parts
To order replacement parts, please supply the part number, the quantity, and
the description of each part desired.
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 illustration and in parts 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.
