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 entire service assembly and the b represents a
sequential number unique to each part within the service
assembly.
The a represents the reference number of
The TORO Company — 2001
All Rights Reserved
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.
