The Caterpillar D9H crawler tractor was introduced in 1974 as the replacement for the D9G. It was only manufactured in the USA.

[edit] Features

The D9H has a D353 turbocharged after-cooled six-cylinder engine producing 410 flywheel horsepower (FWHP). It comes standard with pinned equalizer bar suspension, pilot hydraulic implement system, sealed and lubricated track (SALT), combined braking and steering controls, and powershift transmission.

[edit] Configurations

It is available as a single tractor unit or as a dual model connected front and rear or side-by-side.

The single tractor unit was manufactured with a 90V serial number prefix.

The dual model front tractor, where the operator rides, was given a 97V prefix; the rear tractor has a 98V prefix.

The dual model left hand tractor, where the operator rides, was given a 99V prefix; the right hand tractor has a 12U prefix.

In 1975, Caterpillar added a rollover protection system (ROPS) canopy to the 90V unit, beginning with 90V02277.

In 1978, Caterpillar added an electric hour meter, beginning with 90V06534, 97V00194, and 98V00194.

A certified rebuild was offered for the 90V unit, beginning with 90V75000.

Production of the dual D9H side-by-side tractors (99V and 12U) ended in 1977.

Production of the dual D9H front and rear tractors (97V and 98V) ended in 1978.

Production of the single unit D9H (90V) ended in 1980.

The Caterpillar D9H was replaced by the Caterpillar D9L.
