A cross-section is provided here. Note that, in contrast to the light tanks M3A1 and M3A3, the turret traverse mechanism is now underneath the turret basket floor thanks to the lower height taken up by the new power train. (Picture from TM 9-1727C Ordnance Maintenance--Hydra-matic Transmission and Propeller Shafts for Light Tanks M5, M5A1, and 75-mm Howitzer Motor Carriage M8.)
The rear of the vehicle is detailed in this image. (Picture from TM 9-1727C Ordnance Maintenance--Hydra-matic Transmission and Propeller Shafts for Light Tanks M5, M5A1, and 75-mm Howitzer Motor Carriage M8.)
This sloping front hull plate featured on the M5 and M3A3 Stuarts can be seen above the front fenders on this tank. The characteristic vertical hull sides and raised rear decking that allowed room for the twin Cadillac engines mark this vehicle as an M5. The mount for the .30cal anti-aircraft machine gun can be seen on the turret rear, behind the group of track grousers stowed on the turret. The assistant driver's hatch is open, and although a better arrangement than that found in the M3 Stuart, it is obvious how easy it was for the hatches to be fouled by turret fixtures, especially the 37mm gun.

A detailed image of the front-mounted transfer unit is shown here. This assembly was connected by the universal joints at the bottom of the image to the propellor shafts that came from the transmissions and combined the two power flows into one. It also provided a two-speed hydraulic-controlled gear reduction. (Picture from TM 9-1727D Ordnance Maintenance--Transfer Unit for Light Tanks M5, M5A1, and 75-mm Howitzer Motor Carriage M8.)
The new turret on the M5A1 is shown here. A radio bustle was incorporated, and the AAMG mount has been moved to the turret's right-hand side. The pistol ports on this tank have also been omitted.
This tank features the late-production stowage box on the hull rear, but lacks the shield found around the antiaircraft machine gun. T36E6 parallel grouser tracks are mounted. The filler covers in front of the stowage box were for the engines' radiators, while those near the hull side edges were for fuel.
The rear of the tank was home to two different sets of air deflectors. The engine exhausts, marked by dark discoloration, were routed through the lower screens. The upper screens, able to be hinged upwards out of the way for maintenance, were for the engine cooling fans. Access doors to the rear of the engine compartment can also be seen above the towing pintle.
The removable plate dominates the rear of the turret, and track grousers are stowed on each side of this plate. Details of the antenna mount and cable can be discerned as well.
The rear suspension bogie and trailing idler assemblies are highlighted in this image. The idler had a horizontal volute spring under its protective bracket, and a track skid was mounted on the bracket itself. The suspension bogies also had track skids mounted to the tops of their brackets. There was a hook welded to the lower hull between the suspension bogies on both sides of the tank.
A cross-sectional view is shown here. Note the deflectors in contrast to the M5 above. (Picture from Catalogue of Standard Ordnance Items, 2nd edition 1944, volume 1.)
The cramped quarters in the light tank are apparent in this picture of the crew taking their positions. The door for the assistant driver, when contrasted with the lack of the same in the M3 Stuart, was surely appreciated. A machine gun tripod is stowed on the right fender.
