The Cat 933 Family Includes

933 & 933C

Caterpillar 933 Crawler Loader

The Caterpillar 933F crawler loader was introduced in 1958 in the USA, and production began in Australia the following year. The 933F has a four-cylinder engine producing 50 flywheel horsepower (FWHP). It has a direct drive transmission, and comes standard with an integral loader, D4-size undercarriage, and a large bucket. The 933F was manufactured in the USA, with a 42A serial number prefix; and in Australia, with a 25A prefix. In 1961 Caterpillar added a forward reverse lever and in 1965 and 1968 Cat replaced the 933F with the 933G. The 933G has a D320 turbocharged, four-cylinder engine producing 60 FWHP, and increased bucket size. Production of 933G ended in 1968, however, if properly maintained with our quality undercarriage parts, your Cat 933 loader will continue to perform at a consistent level. We supply only the best replacement parts to maintain the functionality of your Cat 933 series crawler loader.
