GENERAL INFORMATION
The letters A and B in the priority column indicate the degree of importance of each tool.
A. . . . . Indispensable
The toots ranked A in this list are indispensable for performing operations satisfactorily, easily, safely, and
efficiently. It is, therefore advisable that all service shops have these tools.
B.. . . .Selective
The tools in this list are not as necessary as tools ranked A, but all service shops should have these tools
to perform repairs more easily and more efficiently.
Note
l When ordering toot sets that consist of several tools, check the List in the Parts Catatogue
to make sure that some tools are not duplicated in other sets you may already have. tf they
are, instead of ordering the set, order only those new tools that are needed.
l There are new SST explanations in this tool chart.
These tools are indicated by “NEW SST” in description column.
