Case 584D Forklift – Parts, Specs & Serial Numbers

Description:

The Case 584D is a reliable and field-proven rough terrain forklift built for everyday lifting tasks on construction sites, farms, and lumberyards. With a rated 5,000 lb lift capacity, strong power shuttle transmission, and easy-to-service hydraulics, the 584D is a favorite among equipment fleets for its durability, simplicity, and rugged performance.

As a predecessor to the 584E, the 584D offers mechanical dependability over electronic complexity. It features the trusted Case 4-390 diesel engine, solid mast design, and compatibility with a wide range of Case parts still available today.
