AEC Bus Manuals PDF & Wiring Diagram

The AEC Regent bus prototype was built in 1938 with an 8. 8-liter AEC engine (an interim option until the 9. 6-liter engine introduced) and a pneumatic preselective gearbox.

The discovery of a satisfactory British-made replacement for the German air compressor purchased from Bosch would cause problems for AEC once the war began.

The prototype chassis entered service disguised as an old vehicle. Used ladders, which used on the Leyland Titan since 1931, installed on the bus bodies.

While the chassis was being tested, new bus bodies were built at the Chiswick Transport Works in London. They consisted of four compartments and created an overall impression of modern design and functionality. This body replaced the old RT 1 buses, and the buses entered service in 1939.

The AEC Regent III continued to be produced after the war, from 1946 until 1954.

Differences from the pre-war version included different route board designations and locations: the body of the post-war model no longer assembled in London; the pre-war curves near the windscreen and rear of the body replaced with straight lines; and the number of ventilation vents in the lower tier increased from six to four in the post-war version.
