THANK YOU FOR ALL YOUR KIND COMMENTS ABOUT MY PREVIOUS MODEL. THESE 3 FORD AA TRUCKS WILL BE SOON AVAILABLE ON RR AS POSER AND DAZ MODELS WITH MANY DIALS. As the Model T and TT became obsolete and needed to be replaced, Henry Ford began initial designs on the Model A and Model AA in 1926. Basic chassis layout was done rapidly and mechanical development was moved forward quickly. The designs of the Model A shared parts and materials with the Model AA Ford, notably the body, engine and interior. The AA usually received plainer interiors than their car counterparts. The Model AA Ford is powered by the same 201-cubic-inch (3.3 L) I4 engine that the Model A Ford used. The engine produced a maximum of 40 horsepower at 2,200 rpm. The engine featured an up-draft carburetor, six-volt generator, 2 and 4-blade fan, mechanical water pump, mechanical oil pump, electric starter and four-row radiator. All of these features were identical to the Model A Ford except the radiator. The engine could also be crank started if necessary by a hand crank that is inserted through a hole in the radiator shell. The Model AA was based on a chassis that was similar in design to the Model A Ford, except it was substantially larger and heavier to accommodate the work this truck was designed for. Model AA Ford has a four-speed manual gearbox. The additional gear in the transmission is a "granny" or "creeper" first gear with a higher reduction ratio than the first gear on a Model A Ford to provide more torque to move a loaded truck. The second through fourth gears on the Model AA transmission were similar ratios to the first through third gears on the Model A transmission. The Model AA transmission also featured a lock-out on the shift knob for reverse that required a lever to be activated with the thumb so reverse could be engaged. This was done to prevent accidental engagement of reverse while the truck was in motion. Early trucks had a worm gear rear-end that limited the top speed of the truck. That rear-end was replaced by a ring and pinion differential to improve the speed of the truck. The later differential came with high speed and low speed options. Later models were fitted with braces on the outer casing of the rear-end to provide additional support to the rear-end housing. The suspension of the AA Truck was similar to the Model A Ford in the front end. A leaf spring is centered in the front ‘A’ frame over the front axle. Shock absorbers were available for the front end. The rear suspension differed from the Model A Ford. The AA had leaf springs mounted to the chassis and shackled to the rear axle. The rear suspension did not have shocks. The Model AA Ford was available in a variety of body styles from the Ford Corporation. Specialty bodies include: Funeral Coach, Ambulance, Express Pickup, Dump Truck, and a cab without a bed. The cab only model was sold to customers who wanted a custom body to be built by an after-market company. Corporations could have custom paint and other modifications made by Ford for fleets of vehicles. The U.S. Postal Service purchased a fleet of vehicles from Ford that had custom built bodies by outside builders. Overseas production 1929 Ford Model AA at the Texas Transportation Museum Ford licensed the manufacture of the Model A and AA to a variety of nations, notably the Soviet Union. More than 985,000 AAs were built by GAZ in the USSR from 1932 to 1950. The GAZ version had a cargo capacity of 1,500 kg (3,300 lb). A model with stronger 50 hp (37 kW) engine and wartime simplifications is often named GAZ-MM, after the engine. In October 1931 a Model AA was the first vehicle produced at Ford of Britain's own new Dagenham plant in England. The Model AA was also built in several nations in mainland Europe under license from the Ford Corporation. At least three Danish armored vehicles (FP-1, FP-2, and FP-3) were based on the chassis.
