The Caterpillar D4D crawler tractor was introduced in 1963 in the USA, Australia and France. Production began in England in 1964, Japan in 1965, and Brazil in 1969.

[edit] Features

The D4D has a D330 four-cylinder engine producing 65 flywheel horsepower (FWHP). However, there are three units with D315 engines and one with a 3304 engine. The D4D comes standard with either an electric starter or an oil clutch.

[edit] Configurations

It is available in two configurations: the standard model has a track gauge of 60 inches (152 cm); the Low Ground Pressure (LGP) configuration has a 70-inch (178-cm) track gauge. Both configurations are available with direct drive or powershift transmission.

Standard configuration direct drive tractors were manufactured in the USA, with a 20J, 78A, 82J, or 84J serial number prefix; in Australia, with a 49J or 85A prefix; in France, with 44H, 60J, or 86A prefix; in England, with a 88A prefix; in Japan, with a 65J or 91A prefix; and in Brazil, with a 97F prefix. The 91A and 88A have D315 engines.

Standard configuration powershift tractors were manufactured in the USA, with a 22C,  or 83J prefix; in Australia, with a 69K prefix; in Japan with a 47H prefix; in France, with a 58J or 59J prefix; and in Brazil, with a 74U prefix. The 74U has a 3304 engine producing 75 FWHP.

LGP configuration direct drive tractors were manufactured in France, with a 07R prefix, and in Japan, with a 67A prefix.

LGP configuration powershift tractors were manufactured in France, with an 18J or 61J prefix, and in Japan with a 66J prefix.
