CAT D4 7U SERIES
The later D4 series engines quickly increased in power, so the number "4" just became a figure of merit rather than indicating actual engine power. Not sure why 12v wouldnt be more then adequate for the job. The D4 U series was fitted with the more powerful D315 engine. At the time of introduction of the RD4, the D4400 engine produced about 43 horsepower (32 kW) at the drawbar so the 4 indicated the relative engine power. In 1937 the "R" was dropped, and just a "D" was used for the diesel versions. In the right hands, and with a little bit of work. The machine dates from 1955, and while it shows its age, it runs strong, just as youd take for granted from a Caterpillar. rather than the narrower 44' gauge found on the 6U. The 7U machines have a wider 60' track gauge.
CAT D4 7U SERIAL NUMBER
In 1935 Caterpillar had started the naming convention of "RD" for diesel or "R" for regular gasoline, followed by a number to indicate the relative engine size. This Caterpillar D4 carries serial number 7U34757. The RD4 originally weighed in at 10,000 pounds (4,500 kg), and used Caterpillar's D4400 engine, an inline four-cylinders, with a 4.25 by 5.50 inches (108 mm × 140 mm) bore and stroke. The Caterpillar D4 track-type tractor is a small bulldozer manufactured by Caterpillar Inc.Ĭaterpillar first introduced the RD4 in 1936 as the diesel follow on to the successful CAT 30 gas model.
