Kohler Engine Identification Numbers -
The engine model and serial numbers appears on a metal tag or decal that's
attached or affixed to the flywheel shroud, on the carburetor side of the
engine. If there's no tag or decal that originally came with the engine,
or if the engine block was replaced with a replacement short block or if
the blower shroud has been replaced, there's no way of knowing exactly what
year the engine is. All you'll know is the year of the blower shroud itself.
Tags/decals and flywheel shrouds can be swapped from one engine to another
and there are no numbers or identification characteristics on the blocks
themselves (except for the 10hp through 14hp engines has 9 head bolts, the
16hp has 10 head bolts and the 18hp is OHV). Therefore, to see what size
the engine actually is, it's best remove the cylinder head and measure the
bore and stroke to determine engine size. Because a 10hp can be bored and
stroked to a 12hp, using a 12hp piston, rod and crank, and a 12hp can be
bored to a 14hp, using a 14hp piston, rod and crank.
Bore, stroke and valve sizes of the 7hp through 18hp single cylinder Kohler engines are as follows:
| Engine | Early 7hp (K141) | Late 7hp (K161) | 8hp (K181) | 10hp (K241) | 12hp (K301) | 14hp (K321) |
16hp (K341) | 18hp OHV (K361) |
| Bore | 2.785" | 2.938" | 2.938" | 3.250" | 3.375" | 3.500" | 3.750" | 3.750" |
| Stroke | 2.500" | 2.500" | 2.750" | 2.875" | 3.250" | 3.250" | 3.250" | 3.250" |

The IH Cub Cadet production ended and the line was sold to MTD/Cub Cadet Corporation in June 1981. |

The serial number is located in one of the following locations...
NOTE: The model number of the tractor represents horsepower of the engine, and if it's clutch or hydrostatic drive. Odd numbers are hydrostatic (fluid) drive, and even numbers are clutch (mechanical) drive. Example: Model 104 has a 10hp engine with a clutch drive transaxle, model 105 has a 10hp engine with a hydrostatically driven transaxle, model 122 has a 12hp engine with a gear drive transaxle, model 123 has a 12hp engine with a hydrostatically driven transaxle, etc. The only exceptions are models 71 and 73. They have a 7hp engine, but they're both gear drive. Why that is, I have no idea.
The "wide" frame models can only accept a single cylinder engine. The "spread" frame models can accept either a single cylinder or a twin cylinder engine because the frame rails were made wider and they lay down more to clear the cylinders of a flathead twin opposed cylinder engine.
