This vehicle is powered by a 6-cylinder, in-line, water-cooled gasoline engine with a cylinder bore of 135 mm and piston stroke of 150 mm and a compression ratio of 5.1:1. Normal horsepower is 130 at 1,300 r.p.m.; maximum horsepower, 160 at 1,900 r.p.m. The firing order is 1-5-3-6-2-4. Ignition for the vehicle is distributed by a high-tension type magneto. The electrical system includes charging generator; two 12-v., 80 amp.-hr. batteries, and a 24-v. electric starting motor of 8-hp. capacity.
The final drive has a reduction ratio of 2.93:1. A dry multiple plate clutch is used. Both foot- and hand-operated brakes are employed and the vehicle is steered by the clutch brake principle and is said to utilize a locking feature of the control brakes. The transmission is of the synchromesh type with 4 speeds forward and 1 reverse.
Lubricating oil is distributed by gear-type force-feed system through an oil-pressure regulator. The oil-pressure gage registers 29-44 lb. and an oil-level stick is used for checking the crankcase, which has a capacity of 5 3/4 gals. It has been stated that the fuel feed equipment includes a fuel pump between the carburetor and storage tank and that the heavy-duty type of fuel is forced fed to a NIPPON B 45 model carburetor.
There are two models of fuel storage tanks manufactured for this vehicle—one is the Mitsubishi type with main tank holding 70 gals. and an auxiliary holding 43 gals., and the other is the NIIGATA type main tank holding 50 gals. and an auxiliary tank holding 38 gals. Fuel consumption is stated to be 7.5 gals. per hour. The radiator holds 11 gals., circulated by a pump to the engine block. The grade-ascending ability of this prime mover is quoted as 14 tons up a 15° incline, or 32 tons on a
