ENGINE NUMBERS: All engineserialnumbers con-
tain fourteen characters and digits. The first two des-
ignate power train, the next three are the cubic inch
displacement, the next one designates low compres-
sion, the next four are based on a
10,000 day calendar
and the last four designate engine built that day. All
170 and 225 cubic inch engines have the serial num-
bers stamped
on the joint face at right corner, adja-
cent to number 1 cylinder bore. All 273, 318 and 340
cubic inch engines have the serial numbers stamped
on the front of the block just below the left cylinder
head.
All 383, 426 and 440 cubic inch engines have
the serial numbers stamped on the cylinder block pan
rail at the left rear corner below the starter opening.
On all engines, information identifying undersized
crankshaft, oversized tappets, low compression, over-
sized cylinder bores, engine built that day, the shift
and 10,000 day calendar is stamped on the cylinder
block at various locations depending on engine. There
can be as many as fifteen characters and digits
in this
location. 170 and 225 cubic inch engines are stamped
on the joint face at right corner, adjacent
to number
1 cylinder bore, after serial number. 273,318 and 340
cubic inch engines are stamped on the
front of the
block just below the left cylinder head.
383 cubic inch
engines are stamped
on the right bank joint face just
forward of the number
2 cylinder bore. 426 and 440
cubic inch engines are stamped on the
left bank pad,
adjacent to front tappet rail. For additional informa-
tion on engines, see Group

SUMMARY OF LUBRICATION AND
MAINTENANCE SERVICES
Maintenance and lubrication service recommen-
dations for Chrysler Corporation-built Plymouth ve-
hicles have been compiled to provide maximum pro-
tection for the car owner’s investment against all
reasonable types of driving conditions.
Since these conditions vary with the individual car
owner’s driving habits, the area in which the car
is
operated and the type of service to which the car is

subjected, it is necessary to prescribe lubrication and
maintenance service on a time frequency as well as
mileage intervalbasis.
Information pertaining to Lubrication and Mainte-
nance requirements is shown on charts (Figs.
1 and 2)
and on the Schedule.
Vehicles operated under conditions not classified as
normal service for passenger cars, such as in trailer
towing service, operation at higher than normal load-
ing, or police or taxicab operation,require servicing at
more frequent intervals. This information
is included
in each group under the heading “Trailer Towing
Package and Severe Service”.
CLASS1FlCATlON OF LUBRICANTS
Oils, lubricants and greases are classified and
graded according to standards recommended by the
Society of Automotive Engineers (SAE),the American
Petroleum Institute (API) and the National Lubricat-
ing Grease Institute (NLGI).
Engine Oil
The SAF grade number indicates the viscosity of
engine oils, for example, SAE 30, which is a single

grade oil. Engine oils are
also identified by a dual
number, for example,
SAE 1OW-30, which indicates a
multigrade
oil.
The API classification system defines oil perform-
ance
in terms of engine usage. Only engine oils desig-
nated
"For Service MS" should be used. These oils
contain sufficient chemical additives to provide maxi-
mum engine protection. Both the SAE grade and the
API designation must be found on the container.
Gear Lubricants
The SAE grade number also indicates the viscosity
of Multi-Purpose Gear Lubricants, defined by MILL
2105B. An example is SAE 75, which is a light viscos-
itylubricant.

Special care should be taken when raising the ve-

The hoist must be

Floor Jack
A regular floor jack may be used under the rear

CAUTION:
Do not attempt to raise one entire side of
the vehicle by placinga jack midway between a front
and rear wheel. This practice may result in prma-
nentdamageto the body.
