1994 JEEP CHEROKEE Service Repair Manual

If there is not enough space left in the row for all
of the 6-digit SEC code (if used):
²the unused space will remain blank, and
²the code will be listed in the next row.
The last nine positions of row 7 will contain a 2-digit
code, when applicable, and a 6-digit gateline serial
number (same as the last 6 numbers of the VIN).
The last code imprinted on a vehicle code plate will
be followed by the imprinted word END. When two
vehicle code plates are required, the last available
spaces on the first plate will be imprinted with the
letters CTD (for continued).
When a second vehicle code plate is necessary, the
first four spaces on each row will not be used because
of the plate overlap.
ENGINE AND TRANSMISSION/TRANSFER CASE
IDENTIFICATION
When required, refer to Group 9ÐEngines for allengine identification data. Refer to Group 21ÐTrans-
missions for all transmission/transfer case identifica-
tion data.
MAJOR COMPONENT IDENTIFICATION
When required, refer to the applicable service infor-
mation group for major component identification data.
TIRE INFLATION PRESSURE LABEL
The tire inflation pressures label is located on the
glove box door inside panel (Fig. 6). The tires should
also be inspected for visible wear. Also, inspect the
tires for cracks, bulges and other road hazard dam-
age. Refer to Group 22ÐTires And Wheels.
VEHICLE DIMENSION DATA
The vehicle dimension data charts list the exterior
and interior dimensions for each type of Jeeptvehicle.
VEHICLE LOAD DATA
The Vehicle Load Data chart lists the following in-
formation:
²the gross vehicle weight rating (GVWR),
²the gross axle weight ratings (GAWR),
²the cargo weight, and
²the passenger weight for each Jeepttype/body
style.
INTERNATIONAL VEHICLE CONTROL AND DISPLAY
SYMBOLS
Most of the graphic symbols illustrated in the fol-
lowing chart are used to identify various instrument
controls and displays.

SPECIFICATIONS
SPECIFICATION NOTATIONS
All torque specifications listed in this service man-
ual are in both metric system and SAE/English sys-
tem.
WARNING: THE USE OF INCORRECT ATTACHING
HARDWARE CAN RESULT IN COMPONENT DAM-
AGE AND/OR PERSONAL INJURY.
During all procedures, it is important to retain the
original attaching hardware. If the hardware is not
reusable, replace new hardware with equivalent
specifications.
METRIC SYSTEM NOTATION
The following conversion chart will assist in con-
verting SAE/English units to equivalent metric
units.
TORQUE SPECIFICATIONS
TORQUE CHARTS
If applicable, torque chart(s) for screws, bolts and
nuts is/are provided at the end of each service infor-
mation group. Refer to the Standard Torque Specifi-
cations chart and the bolt grade/class identification
illustrations (Figs. 7 and 8).
It is important to be aware that the torque values
listed in the chart are based on clean and dry bolt
threads. Reduce the applicable listed torque value by
10 percent when the bolt threads are lubricated with
engine oil and by 20 percent if new, plated bolts are
being tightened.Various sizes of (Torx) head fasteners are used
as attaching hardware for numerous compo-
nents in Jeeptvehicles.
BOLT THREAD AND GRADE/CLASS
IDENTIFICATION
THREAD IDENTIFICATION
SAE and metric bolt/nut threads are different. The
difference is described in the Thread Notation chart.
GRADE/CLASS IDENTIFICATION
The SAE bolt strength grades range from grade 2
to grade 8. The higher the grade number, the greater
the bolt strength. The grade identification is deter-
mined by the line marks on the top of each bolt head
(Fig. 7). The actual bolt strength grade corresponds
to the number of line marks plus 2. For example:
²a grade 2 bolt has no line marks on top of the bolt
head;
²a grade 5 bolt has 3 line marks on top of the bolt
head;
²a grade 7 bolt has 5 line marks on top of the bolt
head; and
²a grade 8 bolt has 6 line marks on top of the bolt
head.
The most commonly used metric bolt strength
classes are 9.8 and 12.9. The metric strength class
identification number is imprinted on the head of the
bolt (Fig. 8). The higher the class number, the
greater the bolt strength. Some metric-dimension
nuts are also imprinted with a single-digit strength
class identification number on the nut face.
