Canadian Military Pattern Truck - Major Canadian-built Types

Major Canadian-built Types

The Ford-built CMP trucks had a 239 cu in (3.9 L), 95 bhp (70.8 kW) V8 engine, while most of the Chevrolet-built CMP trucks had a 215 cu in (3.5 L), 85 bhp (63.4 kW) straight-6 overhead-valve engine. An American-made 270 cu in (4.4 L) GMC straight-6 engine powered the C60X 3-ton truck.

The Ford and Chevrolet trucks shared a standard cab design, which evolved over the years of production. The first (designed at Ford by Sid Swallow), second and third cab designs were called No. 11, 12 and 13, respectively. The first two type were similar, the main difference being a two-part radiator grille in No.12 cab (its upper part was opened with a bonnet, which was known as the "Alligator cab"). The final No. 13 cab, an entirely Canadian design made from late 1941 until the end of the war, had the two flat panes of the windscreen angled slightly downward to minimize the glare from the sun and to avoid causing strong reflections that would be observable from aircraft. All the CMP cab designs had a short, "cab forward" configuration that gave CMP trucks their distinctive pug-nosed profile. This design was required to meet the original British specifications for a compact truck design that would be more efficient to transport by ship. The specifications also demanded right-hand drive. Internally the cab had to accommodate the comparatively large North American engines and it was generally cramped. The standard cabs were then matched up with a variety of standard chassis, drive trains and body designs. Chevrolet-built vehicles could be recognised by the radiator grille mesh being of a diamond pattern, whereas Ford-built ones had grilles formed of a square mesh.

The production of CMP truck bodies in Canada was subcontracted out to smaller companies in Ontario and Manitoba, organized into the wartime Steel Body Manufacturers Association by the Department of Munitions and Supply. The wide variety of truck body designs included general service (GS), water tanker, fuel tanker, vehicle recovery (tow truck), dental clinic, mobile laundry, wireless house, machinery (machine shop), folding boat transport, and anti-tank gun portee.

In the list below, a drive specification of NxM means that the vehicle has a total of N wheels and that M of those wheels are driven. The military specifications did not permit more than two wheels per axle. The British standard load capacities of 8 cwt (hundredweight), 15 cwt, 30 cwt and 60 cwt correspond roughly to the American loads of 1/2 short ton, 3/4 ton, 1.5 ton and 3 ton, respectively. The 60-cwt CMP trucks were usually called 3-ton lorries or trucks.
