FASTENER USAGE

DESCRIPTION

DESCRIPTION - FASTENER USAGE

WARNING: USE OF AN INCORRECT FASTENER
MAY RESULT IN COMPONENT DAMAGE OR PER-
SONAL INJURY.

Fasteners and torque specifications references in

this Service Manual are identified in metric and SAE
format.

During any maintenance or repair procedures, it is

important to salvage all fasteners (nuts, bolts, etc.)
for reassembly. If the fastener is not salvageable, a
fastener of equivalent specification must be used.

DESCRIPTION - THREADED HOLE REPAIR

Most stripped threaded holes can be repaired using

a Helicoil

t. Follow the vehicle or Helicoilt recommen-

dations for application and repair procedures.

INTERNATIONAL SYMBOLS

DESCRIPTION

The graphic symbols illustrated in the following

International Control and Display Symbols Chart
(Fig. 2) are used to identify various instrument con-
trols. The symbols correspond to the controls and dis-
plays that are located on the instrument panel.

METRIC SYSTEM

DESCRIPTION

The metric system is based on quantities of one,

ten, one hundred, one thousand and one million.

The following chart will assist in converting metric

units to equivalent English and SAE units, or vise
versa.
