Component Documentation

This 300-plus page catalog delivers the exhaustive component listings needed for accurate tractor maintenance. It covers major systems including the carbureted four-cylinder engine, electrical harnesses, chassis, and hydraulic assemblies. Exploded-view illustrations break down the relationship between individual components.

It serves as an essential descriptive reference, streamlining the repair workflow in any active shop.

Technical Fitment Details

The guide documents specific components for gasoline, kerosene, and distillate-burning models. You will find factory part numbers for altitude-specific pistons, including standard, 5000-ft, and 8000-ft variants. Valve seal packages, piston ring sets, and crankcase components are listed alongside their corresponding serial-number fitment notes. Working on heavy vintage agricultural machinery carries inherent physical risks, so cross-referencing exact factory specifications is vital to maintain mechanical integrity and operational safety. This parts catalog provides the authentic OEM numbers required to source the correct items and complete the job right the first time.
