TRUCK ODEL IDENTIFICATION
All 10-35 series odels are identified by the odel
syste shown in the chart on the following page. Basically
the designation consists of 7 characters, 2 letters followed
by five nu bers. The first letter indicates a odel and the
second identifies the chassis type. The first nu ber
designates the GVW range, the second and third identify
the cab-to-axle di ension or odel type and the last two
identify the cab or body style. See Figure OA-1.
VEHICLE IDENTIFICATION NU BER AND
RATING PLATE
A co bination vehicle identification nu ber and
rating plate used on all odels (fig. 0A-2) is located on the
left door lock pillar of C-K-G odels. On Forward Control
odels, it is attached to the dash and toe panel.
The vehicle identification nu ber sta ped on the plate
decodes into the infor ation shown in Figure 0A-3.
ENGINE NU BER
The engine nu ber indicates anufacturing plant,
onth and day of anufacture, and trans ission type. A
typical engine nu ber would be F1210TFA, which would
breakdown thus:
F - Manufacturing Plant (F-Flint, T-Tonawanda)
12 - Month of Manufacture (Dece ber)
10 - Day of Manufacture (tenth)
T - Truck
FA - Trans ission and engine type
UNIT AND SERIAL NU BER LOCATIONS
For the convenience of service technicians and
engineers when writing up certain business papers such as
Warranty Reports, Product Infor ation Reports, or
reporting product failures in any way, the location of the
various unit nu bers have been indicated. These unit
nu bers and their prefix or suffix are necessary on these
papers for various reasons - such as accounting, follow-up
on production, etc.
The prefixes on certain units identify the plant in which
the unit was anufactured and thereby per its proper
follow-up of the plant involved to get corrections ade
when necessary.
Always include the prefix in the nu ber.
