CHEVROLET DYNASTY 1993 Service Manual

TORQUE REFERENCES
Individual Torque Charts appear at the end of many
Groups. Refer to the Standard Torque Specifications
and Bolt Identification Chart in this Group for torques
not listed in the individual torque charts (Fig. 4).
Torque specifications on the Bolt Torque chart are
based on the use of clean and dry threads. Reduce the
torque by 10% when the threads are lubricated with
engine oil and by 20% if new plated bolts are used. Various sizes of Torx head fasteners are used to
secure numerous components to assemblies. Due
to ever changing usage of fasteners, Torx head
fasteners may not be identified in art or text .
METRIC THREAD AND GRADE IDENTIFICATION
Metric and SAE thread notations differ slightly. The
difference is illustrated in Figure 5. Common metric fastener strength classes are 9.8
and 12.9 with the class identification embossed on
the head of each bolt (Fig. 6). Some metric nuts will
be marked with a single digit strength number on
the nut face.
SAE strength classes range from grade 2 to 8 with
line identification embossed on each bolt head. Mark-
ings corresponding to two lines less than the actual
grade (Fig. 7). For Example: Grade 7 bolt will exhibit
5 embossed lines on the bolt head.
METRIC SYSTEM
Figure art, specifications, and tightening references
in this Service Manual are identified in the metric
system and in the SAE system. During any maintenance or repair procedures, it is
important to salvage metric fasteners (nuts, bolts,
etc.) for reassembly. If the fastener is not salvage-
able, a fastener of equivalent specification should be
used.

CAUTION
ALL SERVICE AND REBUILDING INSTRUCTIONS CONTAINED HEREIN
ARE APPLICABLE TO, AND FOR THE CONVENIENCE OF, THE AUTOMOTIVE
TRADE ONLY. All test and repair procedures on components or assemblies in
non-automotive applications should be repaired in accordance with instructions
supplied by the manufacturer of the total product.
Proper service and repair is important to the safe, reliable, operation of all motor
vehicles. The service procedures recommended and described in this publication were
developed for professional service personnel and are effective methods for performing
vehicle repair. Following these procedures will help assure efficient economical vehicle
performance and service reliability. Some of these service procedures require the use
of special tools designed for specific procedures. These special tools should be used
when recommended throughout this publication.
Special attention should be exercised when working with spring or tension loaded
fasteners and devices such as E-Clips, Circlips, Snap rings, etc., as careless removal
may cause personal injury. Always wear safety goggles whenever working on vehicles
or vehicle components.
It is important to note that this publication contains various CautionsandWarnings.
These should be carefully read in order to minimize the risk of personal injury, or the
possibility that improper service methods may damage the vehicle or render it unsafe.
It is important to note that these CautionsandWarnings cover only the situations
and procedures DaimlerChrysler Corporation has encountered and recommended.
DaimlerChrysler Corporation could not possibly know, evaluate, and advise the
service trade of all conceivable ways that service may be performed, or of the possible
hazards of each. Consequently, DaimlerChrysler Corporation has not undertaken any
such broad service review. Accordingly, anyone who uses a service procedure, or tool,
that is not recommended in this publication must assure oneself thoroughly that
neither personal safety, nor vehicle safety, be jeopardized by the service methods they
select.
