seal worth $2000. The foreman does this not because he is a kleptomaniac, but because
management has turned a deaf ear to his pleas to remedy these frustrating impediments.
A good spare parts record contains elements similar to those shown in the spare
parts identification sheet illustrated in Figure 1-32.
Spare parts identification sheets differ from conventional spare parts documenta-
tion or traditional storehouse information in a number of ways. They are primarily
intended as an aid to mechanics, machinists, and turnaround planners. These persons
require that spare parts information be contained on a single sheet, not in separate
catalogs or on computer printouts. In many cases, illustrations are required for posi-
tive identification of parts by personnel unfamiliar with either the machinery or the
storehouse routine.
Major machinery spare parts documentation sheets must contain all the informa-
tion needed by mechanical work forces to locate the parts in the storehouse. These
documentation sheets must allow mechanics, turnaround planners, and inspectors to
verify stock levels, critical dimensions, and suitability of parts. Cross-reference,
design-change, and inspection information complete the sheet and make it a stand-
alone, highly useful document.
