Engine/O.P.E. Model, Type (Spec.) and Code (Serial or D.O.M) numbers.
Model, Type (Spec.) and Code (Serial or D.O.M) numbers are found on every single engine or O.P.E in the U.S.A. You cannot get parts for any engine or power equipment if you do not specify at least the model number. Below, I will explain what most of theses numbers mean and where they can be found.

OHM | Overhead Valve Horizontal Medium Frame |
OHSK | Overhead Valve Horizontal Snow King |
OVM | Overhead Valve Vertical Medium Frame |
OVRM | Overhead Valve Vertical Rotary Mower |

The following two tables contain the last few numbers used in the model number. The first table contains numbers that describe the engine’s horsepower. The second table contains numbers that describe the displacement of the piston. Horsepower interpretations are provided but are not part of the model number.
25 | 2.5 HP |
---|---|
30 | 3 HP |
40 | 4 HP |
50 | 5 HP |
60 | 6 HP |
70 | 7 HP |
80 | 8 HP |
100 | 10 HP |
75 | = 7.5 ci | 3.0 HP |
---|---|---|
90 | = 9.0 ci | 3.5 HP |
100-105 | = 10-10.5 ci | 4.0 HP |
115-125 | = 11.5-12.5 ci | 5.0 HP |
140 | = 14 ci | 6.0 HP |
170 | = 17.0 ci | 7.0 HP |
195 | = 19.5 ci | 8.0 HP |
220 | = 22.0 ci | 10.0 HP |
EXAMPLE OF MODEL NUMBER:
TVS90—-> Tecumseh Vertical Styled. 9.0 ci displacement.H60——-> Horizontal Crankshaft. 6.0 horsepower
EXAMPLE OF SPECIFICATION NUMBER. (SECOND SET OF NUMBERS)
43388F—> Used to allocate proper parts for this engine.EXAMPLE OF SERIAL NUMBER. (THIRD SET OF NUMBERS)
9105B—-> 9= the year of manufacture–1989105= the calendar day the engine was manufactured–April 15
B= the line and shift the engine came from.
The numbers will look like this on the engine’s blower housing=
TVS90 43388F SER 9105B
or like thisH60 67523H SER 2243R
Now Briggs and Stratton, on the other hand, uses an entirely different system. Their model numbers describes the entire engine. Everything from the type of carburetor and governor to the starter and charging system.
6 | 1,2,3,4 | 0-Horizontal Shaft, Diaphragm Carburtor, Pneumatic Governor. | 0-Plain Bearing/DU, Non-Flange Mount. | 0-No Starter with engine. |
8,9,10,11,12,13 | 5,6,7,8 | 1-Horizontal Shaft, Vacu-Jet Carburetor, Pneumatic Governor. | 1-Plain Bearing, Flange Mounting. | 1-Rope Starter. |
16,17,18,19 | 9,A,B,C | 2-Horizontal Shaft, Pulsa-Jet Carburetor, Pneumatic or Mechanic Governor. | 2-Sleeve Bearing, Flange Mounting, Splash Lube. | 2-Rewind Starter. |
22,23,24,25,26 | D,E,F,G | 3-Horizontal Shaft, Flo-Jet Carburetor, Pneumatic Governor. | 3-Ball Bearing, Flange Mounting, Splash Lube. | 3-Electric Starter–120 Volts, Gear driven. |
28,29,30 | H,I,J,K | 4-Horizontal Shaft, Flo-Jet Carburetor, Mechanical Governor. | 4-Ball Bearing, Flange Mounting, Presure Lube on Horizontal Shaft Engines. | 4-Electric Starter/Generator–12 Volt, Belt Driven. |
32 | L,M,N,O | 5-Vertical Shaft, Vacu-Jet Carburetor, Pneumatic or Mechanical Governor. | 5-Plain Bearing, Gear Reduction (6 to 1) CW Rotation, Flange mounting. | 5-Electric Starter–12 Volts, Gear Driven |
35 | P,Q,R,S | 6-Vertical Shaft. | 6-Plain Bearing, Gear Reduction (6 to 1) CCW Rotation | 6-Alternator Only |
40 | T,U,V,W | 7-Vertical Shaft, Flo-Jet Carburetor, Pneumatic or Mechanical Governor. | 7-Plain Bearing, Pressure Lube on Vertical Shaft Engines. | 7-Electric Starter–12 Volts, Gear Driven, Alternator. |
42 | X,Y,Z | 8-Vertical Shaft, Flo-Jet Carburetor, Mechanical Governor. | 8-Plain Bearing, Auxiliary Drive–Perpendicular to Crankshaft. | 8-Vertical or Side Pull Starter. |
9-Vertical Shaft, Pulsa-Jet Carburetor, Pneumatic or Mechanical Governor. | 9-Plain Bearing, Auxiliary Drive–Parallel to Crankshaft. |
The numbers in the first column represent the engine size, in cubic inches. The second column represents the design series. This number is the first digit after the engine size (displacement). The third column represents the position of the crankshaft, the type of governor and type of carburetor. (Second number after displacement). The fourth column represents the PTO bearing, auxiliary drive and reduction gear. (Third number after displacement.) And the fifth column indentifies the type of starter and charging system. (Fourth number after displacment.)
EXAMPLE OF MODEL NUMBER:
12H802—-> 12 CUBIC INCHES DISPLACMENT, DESIGN SERIES H, 8= VERTICAL SHAFT, FLO-JET CARBURETOR, MECHANICAL GOVERNOR, 0= PLAIN BEARING/DU-NON FLANGE MOUNT, 2= REWIND STARTER.
EXAMPLE OF TYPE NUMBER:
2314-19—-> INDENTIFIES THE DECALS, GOVERNED SPEED, OEM ENGINE IS USED ON AND COLOR OF PAINT.
EXAMPLE OF CODE NUMBER:
99032101—-> 99 IS THE LAST TWO DIGITS IN THE MANUFACTURING YEAR (1999). 03 IS THE MONTH, (MARCH). 21 IS THE DAY IN THAT MONTH. 01 IS THE MANUFACTURING PLANT.
The numbers will look like this on the engine shroud:

Hello I have a older Toro 8-25 with Tecumseh motor. I don’t have the motor out. Can you tell me what shaft size is of this engine it’s a TVXL 195. I also have a 10 horsepower Briggs Stratton motor from an older craftsman and would like to know if this would work in my toro 8-25. Thank you for any help. Joe
I was directed to you for help. I have a Craftsman snow thrower as follows:
Craftsman snow thrower, model number: 536-90510HC2
Craftsman engine, model no. 143626292; Serial No. 2257R
Tecumseh engine model No. H70-130168A
7 Horsepower, 15 cubic inches
Tecumseh 120 Volt Electric Snow-blower Starter (motor) Kit, part #33328D.
Crankshaft is tapered, keyed, and threaded. Part #32680A
I would like to re-engine my blower. I need the following information for the above engine:
1. Crankshaft diameter
2. The distance from from the engine base to the crankshaft center line.
3. The distance from the oil seal/cover’s mounting face to the end of the crankshaft.
4. Whether the crankshaft is tapered, keyed, and/or threaded.
5. The engine’s base mounting plate (Tecumseh part #29538) dimensions (height, width, length) and bolt hole spacing.
hello this briggs number system with family numbers is the stupidest thing I ever seen !
I have an Tecumseh engine with a model # of HS40-55282B and a serial # of 0180 02068. I’m guessing it is a 4hp according to the diagram above but the serial number doesn’t look the same as above. Can anyone help me out and tell me the year of the engine? It belongs in a Rupp mini bike.
Thank you
Cory
Trying to get some information for a small engine, not really sure what brand it is. It has “solid state” on the cover, I was able to get the following numbers off the top of the cover.
HH160-170028 SER 6014E It is in a ARGO 6 wheel amphibious vehicle, I was able to make it run with some starting fluid after I took the starter off and repaired it.
From what I know I will be needing a rebuild kit for the carb and either a rebuild kit for the fuel pump or a new fuel pump. Fuel and air filters a new plug.
If you are able to source the parts I’m good with that, not sure if you do that on this site or not. For shipping information I’m in zip 23175

I picked up a small Craftsman 3/20 snowblower (used) needs a little work but fired right up. Had a fuel leak so decided to change fuel hoses, bowl seal etc. Upon cleaning the carb a portion of one of the tabs that float pin goes thru broke off ( now needs a carb). The model # of the blower is 536.884220 code 8257 the # stamped on the top of recoil assembly housing is 200.681081 8221( only #’s i could find on engine) i was told by local repair shop that its a Tecumseh eng. The part # they gave me for a new carb is 640092A. Upon looking on line im just not sure if thats correct. Any help would be greatly appreciated. Thank you
by far the best description of the serial numbers identification for the briggs and tecumseh engines, tanks alot
What is the horsepower of my Tecumseh engine model# 143-592022. I think it’s 12 but not totally sure about it. Thank you!

I have a old eskimo ice auger that has a tecumseh 3hp motor on it model #2ooo-3 serial number 10107 i lost the spark plug and have no idea what the plug number is. Can you help?
Too bad this isn’t very well written.
Your chart below B&S has no correlation to your examples which is why you have so many questions below it about it.
