Parts Catalog

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 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.
