Reference Numbers
There are special reference number formats for parts in service assemblies and indicating quantity in illustrations. Service Assembly Reference Numbers are in the form a:b where a is the assembly reference number and b is the unique part number. Reference Numbers Indicating Quantity have the form nX y where n is the quantity, X is the multiplication symbol, and y is the reference number.

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 catalogue 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 tyre 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 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.
