Service Assemblies

Parts within service assemblies have reference numbers in the form

X:Y. X

is the reference number of the service

assembly and

is 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 part lists and as callouts in illustrations.
