Maytag Upright Engine 1915-1923

The first self powered wringer washing machine was the Model 43. The first engines came with a battery powered ignition as shown above. In 1918 a magneto ignition system was added with the Model 44.

Maytag Fruit Jar Engine, September 1921 Through March 1923

The Maytag Fruit Jar Engine is arguably the most collectible of all the Maytag engines.
But be warned, due to their value, there have been Replica engines made.

A Ball Mason canning or fruit jar was used as the fuel tank.
There are no records to prove that anything other then the standard Ball Mason jar of the day was used. Model 82 and 85 were generally know as the model 82 MULTI-MOTOR. According to calculations based on the dates of specification sheets and on production records, a total of between 2200 and 3400 Fruit Jar MULTI-MOTORS were produced. Fruit Jar Engine serial numbers are generally found in the #99860 through #111301. The Fruitjar engine was built during the last two years (1921-1923) of Upright production. The Fruitjar engine used the same Johnson magneto type as the 1/2hp Upright.
Although a few Fruitjar engines are known to have the Quick Action Magneto.
If this was production or a later field retro-fit is not known.

Maytag later model 82

The model 82s used a Johnson magneto. But a few beginning in June 1927 were produced with Bosch FY-ED2 magnetos. There were both 11 and 9 fin cylinder model 82 Multi-Motors. The 11 fin cylinder came first on the 82 then at about the time of the change to the long frame S-223 tank this changed to the 9 fin cylinder. So some long frame engines are seen with 11 fins and some short tank engines with the 9 fin as well. Circumstantial evidence indicates that around 15,680 11 fin multi-motors were produced.
Also the first model 82 multi-motors came with the S-216 fuel tank that looks similar to the late Upright fuel tank. Then shortly after they changed to the S-223 long frame fuel tank. There are at least 3 and maybe more notable variations to the S-223 tank in evidence thru production. The early model 82 Multi-Motor was enameled blue. Beginning April 20,1926 with "Washer" # 56333, Subsequent model 82 Multi-Motors were enameled green.
The Upright, Fruitjar and Model 82 engines shared the same basic E type carb with some minor variations thru prod

Maytag Model 92 Multi-Motor, August 1927 Through August 1937

Maytag Introduced The model 92 single cylinder horizontal kick start in August-September 1927 Assembly #3902 It was rated 3/4 h.p. and is a 2 Cycle design engine with a 2 1/2" bore and 2"stroke. The Bosch FY-ED4 magneto was standard on the model 92. The model 92 was the first Maytag washer motor to have as part of the engine a kick pedal for starting. The kick pedal of the model 82 is earlier but it was part of the washer not the engine. The 92 was used on models 92, 62, B, G, 16, 26, 31, 11,
N11, 110, 19, 11.111 and 33 washers. The engine was adaptable
to each model of washer by changing the fuel tank.

The fuel tanks came in three versions, # S-231 for the model 92 and model B washers, # S-279 for the model, G, 16, 19, 26, 11.111 & N-11 washers and # S-284 for model 31, 33 and the Toy Racer. There is a fourth tank also part numbered S-279 and it is different from the commonly found S-279 tank. What the reason for this variation was and why a unique part number for it was never assigned is not known. This odd tank is hard to find.

Interesting variations appear on these engines with two being of significant interest. The earliest feature or variation earns the early 92 engines their nick name, The Side Exhaust. There were two exhaust manifolds used on these engines. The S-252 "Elbow connection" as Maytag called it or side exhaust manifold as its called today and is the earliest version and was used for only a short period of time from August 1927 to March 1928. The S-260 is the second version and replaced S-252 at approximately 266000. The side exhaust engines are eagerly sought after. There are other features specific to the side exhaust that are found only on an early 92. But too numerous to go into here.

The second major variation is the model 19 found late in production 1936 to 1937. The Model 19 has a different Kick pedal, segment gear and segment cover. Part numbers S-295 / S-296 / S-297 The pedal and segment gear resembled those of the later twin cylinder engines. This change was necessary to adapt the engine to the model 19 Washer.

There were two caution plates and a variation. Part #12903 is the first for the models 92 and began at about 281000 and had the 92M embossed in it. And later #13474 this plate had blank spaces to allow for the hand stamping of the various model numbers. Then for the model 19 part #13474 was modified by cutting the mounting tabs off the bottom of the plate so it would fit under the Maytag Script of the S-297 segment cover. The caution plates did not specify a model of the engine but rather was the model tag of the washer that particular engine was installed on.

There are many other differences in the production run of the model 92, but these will do as a highlight.

See the book Maytag Multi-Motors by Larry and Marge Benton for more interesting information on these engines. Available through the Maytag Collectors Club.
