We ran a Deutz air-cooled V-8 diesel engine for several years in a large Liebherr track type excavator, (2-1/2 yd bucket), and it was very good, very fuel efficent, and very strong engine. It was oil cooled, with 2 large oil coolers that served as radiators, one for each bank of cylinders, and about 10 gals. of engine oil. Oil coolers are definitely the key to cooling these engines. The higher operating temperature of the air cooled engine's cylinder, along with the turbo charger burned the fuel very completely and very cleanly, as long as the coolers were kept cleaned off it was good, when they clogged, the engine would sieze the piston to the cylinder jugs.We finally had to change it out and replaced it with a Detroit, which was water cooled, but not as good at fuel economy and less h.p. per c.i.d. We never could depend on a parts supply the last dealear kept it for about 6 years,and we finally just left it with him and never heard any more from him, that was in '74!
