Ordering Replacement Parts
To order replacement parts, provide the part number, quantity, and description of each desired part. Each part in the illustration has a reference number that corresponds to the parts list.

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.
