The piston must be installed with the split side facing the engine left side. The engine is seen in the direction of travel.

The connecting rods mounted facing the hole for splash lubrication is the camshaft.
The oil pump should be on the oil pan bottom and have a spring attached underneath. It should not be screwed.
On assembly the temporary screw hole on the right side of the motor used to keep the oil pump in position.
The manifold can loosen if the screw on the right side of the cylinder head is unscrewed. Loosen the lock nut first. Then lift the distributor and release the ignition wire by spinning the distributor so the cable can be threaded out. If the manifold is strucked gently lift under the distributor housing until it loosens.
We take no responsibility for the information above is Ford’s latest recommendations and they may be used on your own responsibility.
Oil leaks are common on the A Ford Motors. Unfortunately, in many cases traced to too bee to much play in the rear main bearing.
Do you have significant leakage contact us for ytterligre tips or talk directly to the club you belong to. First check that oil fille tube  not is  blocked or covered. The lid on the oil filler tube must not be tight. Excessive pressure in the engine and can be a reason for  a major oil leak.

Oil that normally is used for the Ford Model A Engine is a Mineral Oil SAE 40W,  SAE10-50W,   SAE 20-50W. Oil quality and type of oil is alway under discussion so use the oil you find best.

We use the 20-50W mineral oil and that works fine.



All in Swedish.  Kolven skall monteras med den delade sidan vänd mot motorns vänsta sida. Motorn ses i färdriktningen.Vevstakarna monteras vända så att hålet för stänksmörjningen blir mot kamaxeln.Oljepumpen skall stå på oljetrågets botten och ha en fjäder fastsatt under sig. Den skall inte skruvas fast.Vid montering kan tillfälligt skruvhålet på motorns högra sida användas för att hålla oljepumpen i läge.Fördelaren kan lossas om skruven på topplockets högra sida skruvas ur . Låsmuttern lossas först. Lyft sedan fördelaren och lösgör tändningskabeln genom att snurra fördelaren så kabeln kan gängas ur. Sitter fördelaren hårt bänd försiktigt under fördelaren tills den lossnar.Vi tar inget ansvar för att ovanstående uppgifter är Fords senaste rekommendationer och de får därför användas på eget ansvar.Oljeläckage är ofta förekommande på A-Fordmotorer. Dessvärre kan det i många fall härledas till för stort spel i bakre ramlagret.Har du betydande läckage kontakta oss för ytterligare tips eller vänd dig direkt till den klubb du tillhör. Kontrollera först att oljepåfyllingen inte är igensatt eller täckt. Locket på oljepåfyllningsröret får ej vara tättslutande. Då bildas övertryck i motorn och därmed ett stort oljeläckage.Lycka till.

Ford Model AA Truck

The Ford Model AA Truck Pages

These pages are aimed for Trucks, Buses, Tractors and other commercial Ford vehicles.
If you have any pictures and stories to tell, e-mail us or send a letter direct to NetClassics –
The new Ford truck was built for the needs of tomorrow.
Cabs and bodies were in rock moss green pyroxylin finish with gray striping.

Ford four- cylinder engine

The same engine as in all Ford A. With 200.5 cubic
inches in displacement it was a very powerful Truck
engine. It did develop 40-brake horsepower at 2200

The dual transmission

Good appearance and through, all-around sturdiness are outstanding features of the bodies of the New Ford Truck. The standard equipment bodies were the platform body with stakes, grain sides, or cattle racks. There were also
the Express body and the panel body.

Ford Model AA TruckClosed Cab
Ford Model AA Truck

This body could easily accommodate the driver and two passengers.The doors were wide and windows could be raised and lowered by a revolving lift. The seat was comfortable and 44 inches wide and 17 inches deep. Upholstery was brow arificial leather and the floor had a rubber mat. One of the features was the rear window and the rear view mirror. No PB PS AC as we are used with today.

Express Body

A truck with generous loading space and sturdy construction was features of the express body. It was really a “wide bed”, from the floor to the top of the sides was it 12.5 inches. Inside dimensions were width 4 feet and length 7 feet and 2 inches. There were also sockets for stakes, racks or slide boards. Th end gate was made of steel and equipped with heavy chains.

Stake Body

The Stake body was wider than express body. The “bed” was 5 feet and 8 inches wide and 8 feet and 1,5 inches long. This type of truck was also common in Sweden but the body and bed was not manufactured in the U.S. The trucks came as chassis to Ford Motor Company in Sweden or Denmark. Almost 100% of the truck bodies were made here in Sweden. The reason for that was the tax system.

Panel Body

The panel body had a total different bodystyle and was constructed of a combination of woodfinished interior and metal exterior. There were two folding seats that gave the driver easy access to the interior of the body. Loading dimensions were width 43 inches, height 50 inches, length 88 inches. The spare wheel was placed on the right side of the body just behind the door of the cab.

The new Ford light commercial cars

The new Ford light commercial cars were all built on the model “A” chassis. There were several types of commercial cars that Ford did offer. The Pick-Up closed or open, The De Luxe Delivery car and the Panel body car.

Pick-Up Body

The Pick-Up body was offered with either open or closed cab. The body was made of steel with heavy floor boards and steel strips to withstand the wear. The size was 40 3/4″ in wide adn 35 inches long, 13 inches in height and the loading capacity was 17 cu. Ft.

De Luxe Delivery Body

This car looks like a Tudor without the rear side windows but it is not the same body. They differ a lot. The side “window” is larger than it is on the Tudor. More things differ but lets look at the picture and see how nice this commercial car looks like. This car was designed for destinctive delivery service and followed closely passenger car lines. The body was all in steel. There was a rear door on this type of car so the sparewheel was placed in one of the front fenders.
It also had rear bumpers. Nice little car this Delivery.

Panel Body

This car was built the same way as the AA Panle Delivery Truck. The exterior was metal and the interior wood. It had double rear doors and was longer than the De luxe Delivery car. The drivers compartment was fully closed and had two folding seats.

The development went on and 1931 the trucks looked like this in Ford France Magazine. The same magazine also shows tractors and Ford cars. The trucks were sold with arguments as: Quand vous examinez la question du transport èconomique.. Songez au prix de la tonnekilomètriqe. Ford -Puissance -Sècuritè -Comfort. Does anyone want to see more of those interesting pictures please mail us via and just tell us what you would like to see on our pages and we will try to arrange that for you! Just call, write, fax or mail us your ideas.

Foreign Ford A Trucks

A lot of factories/companies abroad made their own AA Truck bodies and some of them were sold by the Ford Motor Company. In Sweden there was a lower salestax if the car was assembled in Sweden. That was one of the reasons why Ford Motor Comapany almost to 100% imported just the AA chassis from USA. As you can see on following photos from Ford Motor Company A/Bs (Sweden) magazine “Ford världen” 1932 the Swedish AA bodies were different from the American built bodies.

The Ford trucks low maintaining cost and Fords very good technical standards was some arguments that often were used to sell Ford. This photo shows one of the AA trucks that was sold during 1932 from Ford Motor Company in Stockholm. The construction of the beds and the size of the cab differs from the American trucks. We normally did build the trucks this way and the narrow or wide beds were almost never used. Compare the cab of this truck with the trucks below .

This is a 1930-31 AA sold 1932. It was equipped with black headlights and black radiator shell.

AA trucks used by “Olaus Olssons Nya Bilimport” in Stockholm . The front bumpers looks like the bumpers that were used on “normal” Fords, as the Tudor.

These cars were in daily use to bring fresh bread out to everyone in Malmoe (a quite big town in the south of sweden). The bakery that used those 15 Ford Deliverys was “A/B A.Pålssons Bageri Malmö”. I can`t say if it is US bodies, Danish or Swedish on those cars. Maybe someone knows. Just tell us and we will add the new information to this page.

In Malmoe we also find more users of the AA truck as well as the TT-truck.. “A/B Malmoe Mjölkcentral”( Milkcentral ). Here is another cabtype found and the front bumper is not the normal AA-bumper. The hood are painted in black. Can anyone of our Swedish readers tell us something more about this picture? We can se the drivers standing behind the Trucks. Look at the TT truck with the very nice window behind the door. If we look closely we can also see that Truck number two with the black roof has a cab that differs from the first and third one. Ford was obviously selling several Truck cabs and also naked chassis and the customer ordered his own customized cab. It is interesting to talk about what is ORIGINAL . Today we still prefer the American built cars as we feel that those cars are more original but isn`t the Swedish built AA trucks are the most original you can have here in Sweden? I think so. I do hope that someone writes a book about all Swedish bodybuilders. If anyone have any type of information about Truck bodies built in Europe please contact us. If you can`t write down the information just call us and we will do it for you.

At the firm Flobergs Biltarnsport in Goteborg Sweden they used this type of AA trucks. The cowl and hood was in darker color than the cab. The front bumper the normal AA bumper and the shell and lights were black.

One of the trucks below is from an Ad that Ford published in Fordvärlden 1932 and it has some interesting things I think we can look at. No rear fenders just some piece of splash metal in front of the rear wheels. The running boards were very long and it looks like that they were cowered with rubber. The cowlband was painted in the same color as the moldings and radiator shell and headlights were black. The license plate is a interim plate that you have on your car for maximum one month before you got the correct license number. They were red with white text. A stands for Stockholm. B was just outside Stockholm and C was Uppsala. That was a nice system as you could se from what place in Sweden a car came from.

This picture (see below) is from Fordvälden 1932. The pricelist gives the information that a A Chassis was priced at 2100:-skr ( approx 350 dollars ) and if you wanted a closed cab ( paketvagn) you had to pay 110 dollars extra. That was 38,5 % more than just for the chassis. Ford Service warranty and service was really good. What do you say about this?

  • Warranty without any timelimits.
  • Three free inspections during the first 2000-3000 km
  • Low priced spareparts
  • First class service
  • Standardized workingcosts
  • Free delivery to any Forddealer

In Denmark 1929 we found following information to read in “Ford Magasinet”.

The AA is classified as 11/2 ton truck but with twin rear wheels it can load over 2 tons. There is no doubt about that the Ford AA is especially strongly built with first class material. The weight was just 2282 English pounds. Strange to find the weight in Pounds, but it was given that way. the wheels were spoke wheels and the bodies were built in Denmark.

This truck (see picture below) was built for pig transport. The sunvisor is extremely long and the front window is bigger than we normally see.

The Ford AA Ambulance

To take care of the car was a specialty for Ford but someone had to take care of us. How about a ride in this Ambulance (see picture below) ? It was delivered by The Ford dealer in ESBJERG, Hr.A:E:D: Bruhn. THE Ambulance was manufactured at Bruhns own garage. The Ambulance was equipped with long soft springs and “Lovejoy” shocks. The tires were balloon tires 32×6,00. The body was built on wood and covered with aluminum. The interior was covered with white artificial leather. And the inside floor with linoleum. The runningboards were covered with rubber and the running board trim were made of solid brass and nickel plated. The car was also equipped with extra heating system to be used during cold winter days. In the summer cold air to the patient compartment was arranged via a special tube construction. Almost AC. There were also inside lights placed in the roof and they was activated by opening some of the doors. Special lights were also placed on several places inside the car that all could be turned off or on by the driver. The drivers comfort was also very good. For safety the car had a strong hedlight placed at the left windshield post. The total weight was 1650 kg. Very Good Indeed. Look closely and you find the turn signals in front on the windshield posts. It also had a outside mirror and automatic windshield wiper. A nice AA indeed.

The fenders were in the same color as the body and there are also some other interesting things to look at. There is only one rear lamp and it is placed on the right rear end! You find a rear runningboard under the body but for how long was that one intact ? The runningboards seems not to fit so properly towards the front and the rear fender. Maybe they were made of wood and some thicker than normal and therefore came a little bit higher up on the body. Ambulances normally have red lights but this one have not got that yet. No extra sirens are visible but the Ford horn is there and it`s painted in the bodycolor. The front lights are painted but the rims looks like nickel or black. The radiator shell is in bodycolor.

The body manufacturers in Sweden were several small and some bigger ones. Åtvidaberg was one of the most known and they are still making bodies for trucks and commercial cars. It is interesting to see the forms and sizes of the body they had chosen to the Ford AA chassis. In size it is a little bit wider and longer than the US cab. The same body was also used for Chevrolet. (A Chev and Ford with the same body, yes but it was a long time ago.) .

Ford History

Ford  History


The Ford history starts already 1903. Between 1903 and 1908 Ford built cars in a small scale. All were named after the 19 first letters in the alphabet. The first car was the Ford A.

1927 the name turns up again and now as the Ford A that the whole world was waiting for. If the time ever can run out on Ford it did run out of the Model T 1927. Fords competitors on the market was 1927 offering modern more powerful cars than the Ford Model T could match. On May 1927 all Ford plants across USA closed down while the Ford Company constructed and retooled for the new Model A.


The “New Ford Car” was one of the biggest news stories 1927

Panic situation at Ford

The expectations was enormous about the new Ford, but was it possible for Ford to once again make a success ? Ford engineers worked hard watched by media in all possible ways.

The “New Ford Car” was one of the biggest news stories 1927. Henry Ford promised a “complete description within a few weeks” already in may 1927. The weeks seems to have been long that year.
Fords advertising agency had in June new ads done on the new Model A. Strictly confidential of course but somehow they found their way out to the media.
12 cylinder Ford ?

New York News Bureau released the description and the ads. It was a real panic situation at Ford. Ford´s advertising agency denied the ad as the correct description for the new Ford A. Just “fiction and imagination ” But there is “never a smoke without a fire” so the media was hungrier than ever . The media speculations about the car became wild and the rumors said that the car had a 12 cylinder engine, was electric, was a diesel and so on.

Waiting was not a name for it. A nation was suffering and expected and Henry Ford to make a car that would be another pacesetter.

Between May 25 and until August 10 1927 no statement from Ford about the new car was issued. Edsel Ford announced ” The New Ford Automobile is an accomplished fact. The tests already show that it is faster, smoother, more rugged and more flexible than we hoped for.

On the 11th of November 1927, 6 months after all factories stopped making the Model T, a new Ford driving on the street was spotted by a reporter from Brighton Argus ( Michigan).
A “scoop” indeed for a small town paper.
The New Ford Car was a pea-green Tudor with wire heels, speedometer, bumpers, 4-wheel brakes, standard gearshift and bullet-shaped headlights.
Argus wrote ” This is strongly suspected of being the new Ford “Mystery” car.
On December 1927 was the Model A introduced to the market. 1.250.000 NYorkers saw the Model A during the first 5 show days. Movies and photographs were distributed all over USA.

Ford dealers with empty showrooms

Many Ford dealers showrooms had no Model A to show during Jan Feb , Mars April, and May 1928. In may they got window posters from Ford ” wait for The New Ford ” You must say that the Forddealers were brave.

Even late summer 1928 there were not many dealers that had got a model A on the display. In June the dealers got a folder from Ford Motor Company showing the Ford and with explanations why that A was so long delayed. “

Fords president passion for improvement ” and the long running start to stock up the assembly plants.


The New Ford – Success!

To solve the problem with empty showrooms, Ford representatives drew cars from dealer to dealer to make it possible to show the car for one hour in each town. By January 10 1928 727.000 Model As were sold and that with empty showrooms! The production in early January was about 125-140 cars per day. The production increased dramatically and the market welcomed the Model A. The public pronounced the Model A as the complete success! The millionth model A was produced February 1928. At that moment Ford manufactured 7500 cars per day! In June Ford set record with 9100 cars on one day.

Ford outstanding again!

Ford was once again the leader in Automobile production. Ford A was produced during 1928-31 in more than 4 000.000 units. A lot of them still remains today and more cars will be restored every year. Just in Sweden there are about 3500 As today (2012)

Ford on it`s way to Sweden

In January 1928 wrote the newspaper “Svenska Journalen” like this: The New Ford car “for every man” is on it’s way to Sweden. They also had a story about The development of Ford Motor Company. Svenska Journalen was a newspaper mainly for households and they normally didn`t write about cars. Some interesting pitcures were shown as “The New Ford Car” and it looks like the pictures are from England. The Ford A has small lights on the fenders.

They also made a comparison between one of Henry Ford´s first cars and The New Ford A. They can also tell us that the difference is notable. If you look closely it seems like the front bumper on the Ford behind the old Ford car has open ends. That gives us the information that even cars in England had open bumper ends. The often heard theory that only 200 of the very first cars were equipped with those bumpers can that still be correct ? If this was one of the pre series cars why put on fender lights just for a visit in England? Can anyone of you give us the correct answer?

I belive that the first 200 Model As made not was the first 200 that left the factory. My theory is that even nr A189 was put together during a longer period and not neccesary had all very eraly options. For example then gas tank, rear fenders etc can be original even if they seems to be of a later production date. It may have been”updated” at the factory and delivered 30 days later than made ( Lars Hedstrom Nov 2012 ) It was on the road in Sweden as early as in February 1928.



Ford Model A life time is 7 years

This picture, also from England tells us that this sportscar for sure will become popular. This Sport Coupe has also open bumper ends and fender lights. Do we have two of the first 200 cars standing in England January 1928 ?

 In the text I can read following  ” From birth to death is a Ford cars lifetime about 7 years but there are some long living cars that stands for 14-15 years”.

My friends what do you say about that ? We know better and just here in Sweden we have at least 3500 Ford A cars. (2012) Approx. 1000 of them can be driven on our roads today.

Suppose that the picture was taken in USA, then we have something else to think about. Why has the car fender lights if it is at the factory in USA?

If you look closely on the background on the picture with the Sport Coupe you can see some windows on the factory or place were the car was located. Look at this picture published in the same article. The windows looks similar.

I think it is interesting to see those very early cars in England and I know of several very early cars now existing in Denmark and Sweden. We have had the 189 car here and one with frame number and engine number about 1000 and one engine about 500. Finland got one of it`s first Ford A deliverd with engine number 1500. That was a Tudor. If you know of anyone that have a very early Ford A please let us know. It you want to we can publish it here at NetClassics – info(x )  x=@

Ford in the Air

Fords interest in airplanes were intensive and you can see him standing

in front of one of the airplane that the Ford factory did build.





Ford Model A in Sweden

In Sweden the ads for the new Ford A showed up. Below is an example from Klaes Jansson, Ford dealer in Falun Sweden.
