About The Caterpillar 943 Crawler Loader

The Caterpillar 943 was introduced in 1980 and began production in the USA and France until 1992. The CAT 943 has a 3204 direct injection, four-cylinder engine producing 80 flywheel horsepower (FWHP) and a hydrostatic transmission. It also features a rollover protection system (ROPS) cab, electronic monitoring system (EMS), sealed and lubricated track (SALT), oscillating undercarriage, Z-bar linkage, and a 14.2-inch (36-cm) track shoe size. Caterpillar increased the 943’s digging depth in 1983 and and added a new brake control system and dual setting relief valve in 1984.In 1990 Cat added a general-purpose bucket with fabricated hinges and a vertical face on the back. Almost 6,000 Cat 943’s were made, and many of them are still on the job. When maintained with our quality undercarriage parts, these Cat 943 crawler loaders continue to earn their keep.
