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 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.
