The JaG-3 ( Russian ЯГ-3 ) was a two-axle truck made by the Soviet manufacturer Jaroslawski Gossudarstwenny Avtomobilny Sawod (JaGAZ for short, from 1933 Jaroslawski Awtomobilny Sawod , JaAZ). It was produced in series from 1932 to 1934, with around 2700 copies being built. The vehicle, which was located above the AMO-3 , was replaced by the JaG-4 in 1934, which differs from it only through a different engine. Today there is probably no JaG-3 left.

The JaG-3 was the first truck from Yaroslavl with the abbreviation JaG in the type designation, which stands for Jaroslawski Grusowik (Russian ярославский грузовик, translated Yaroslavl truck ). In terms of design, it largely corresponded to the Ja-5, which had been manufactured since 1929 . The truck was able to transport five tons of freight with a dead weight of 4750 kg. It was constructed in a long-hood design, the power transmitted to the rear axle via a mechanical four-speed gearbox. Both chassis without a body and vehicles with a wooden platform were delivered from the factory.

The main difference between the vehicle and its predecessor was the engine used. The JaG-3 received the in-line six-cylinder gasoline engine of the AMO-3 . Powerful truck engines were previously imported by the US Hercules Engine Comany , since no suitable engines were manufactured in the Soviet Union itself in the 1920s and early 1930s. For years, the Yaroslavl factory did not have enough engines of the right power class available for its trucks. The domestic engine of the AMO-3 was also too weak for the JaG-3. The vehicle was therefore geared up to be shorter than the Ja-5, and the top speed dropped from 53 to just 40 km / h. The engine used produced only 60 HP (44 kW) and thus 33.5 HP less than the six-cylinder Hercules-YXC of the predecessor. The cubic capacity also fell from 7020 to only 4880 cm³. At the same time, fuel consumption rose from around 35 to 48–75 l / 100 km.

Most JaG-3s were built in 1932 and 1933. In 1932 about 350 Ja-5s were produced at the same time, and another 36 in 1933. The following table shows the production of the JaG-3 by year of construction:

Construction year 1932 1933 1934 total
Pickup truck 647 1678 83 2408
Chassis 41 244 0 285

A total of 2693 JaG-3 trucks were built. In 1934 the successor JaG-4 was introduced, of which over 2,300 units were built in the same year. It differed only in a different engine, it received the drilled block of the ZIS-5 with 73 HP. It is not clear whether a JaG-3 has survived to this day.
