The Caterpillar D7F crawler tractor was introduced in 1969.

Features & Configurations

It retained the same track gauge as its predecessor at 78 inches (198 cm). The D7F had a D333T six-cylinder engine, producing 180 flywheel horsepower. It came standard with hydraulic track adjusters and rollover protective structure and was offered with the choice of either direct drive or powershift transmission. Direct drive tractors produced in the USA had a 93N prefix, while units with powershift transmission were given a 94N prefix.

In 1974 Caterpillar began production of the D7F in Japan. A powershift 92E model was produced as well as a direct drive 91E model.

[edit] Modifications

In 1973, a two-piece master link was added to the tractor, beginning with 93N01397 for direct drive units and 94N06659 for powershift units.

A sleeve-metering fuel system was added to powershift units beginning with 94N06660 in 1973 and to direct drive units beginning with 93N01556 in 1974.

An updated transmission (2P) was fitted to serial numbers 94N 5192 and up.

The Caterpillar D7F was replaced by the Caterpillar D7G.

Production of the D7F ended in the USA and Japan in 1974. Based on data from the sales database of Ritchie Bros. Auctioneers, it is estimated that more than 15,700 were produced.
