Component Walkthrough and Parts Identification

If you spend time turning wrenches on a vintage Cub, guessing part numbers just leads to delays and wrong orders. This catalog lays out every major assembly for the Farmall and International Cub lines. The document breaks the machine down into seventeen major groups. You get clear looks at the chassis, electrical systems, engine components, transmission internals, and final drive assemblies. Rather than simple lists, the exploded views show exactly how things fit together. They pinpoint the exact fasteners, gaskets, bearings, and shafts required based on your specific tractor serial number.

Specification Highlights

Beyond just part numbers, the documentation provides the baseline identification data necessary for accurate component replacement. It details the C-60 gasoline engine displacement at 59.5 cu in (975 cc) operating at a rated 1650 rpm. You will find exact system capacities, like the 9.75-pint cooling system and the 7.5-gallon fuel tank. Need to verify measurements before ordering internals? The manual defines main bearing clearances at 0.002–0.004 inches. It also lists differential and rear axle torque settings at 40 lb-ft for specific load applications. Please remember that while these specs guide accurate component identification, you must always rely on proper shop procedures and OEM safety protocols before applying torque or beginning heavy maintenance.
