CHAPTER 1 GENERAL INFORMATION
ENGINE IDENTIFICATION
Tecumseh engine model, specification, and serial
numbers or date of manufacture (D.O.M.) are stamped
into the blower housing, or located on a decal on the
engine in locations as illustrated (diag. 1 & 2). The
engine identification decal also provides the applicable
warranty code and oil recommendations (diag. 2).
Interpretation of Model Number
The letter designations in a model number indicate
the basic type of engine.

The number designations following the letters indicate
the basic engine model.
The number following the model number is the
specification number. The last three numbers of the
specification number indicate a variation to the basic
engine specification.
The serial number or D.O.M. indicates the production
date of the engine.
Using model

, serial
5215C
as an
example, interpretation is as follows:
OHV16-204207A
is the model and specification
number.
OHV

Manufacture)
5
is the last digit in the year of
manufacture (1995).

indicates the calendar day of that year
(215th day or August 3, 1995).
C

the engine was built at the factory.
Emissionized engines that meet the California Air
Resource Board (C.A.R.B.) or the Environmental
Protection Agency (E.P.A.) standards will include
additional required engine information on the engine
decal.
NOTE:
