The transmission in a farm tractor is a complex mechanism made up of many different parts that work together to enable smooth gear changes and efficient transfer of power from the engine to the wheels. Knowledge of the basic components of a transmission and their functions is crucial to successfully perform repairs and maintenance. Below is an overview of the most important gearbox parts and tips on purchasing and replacing these components.

Main parts of gearbox:

• Shafts (main shaft, intermediate shaft, output shaft): Transmit torque and work with gears to change gear ratios. They may require replacement if worn or damaged.
• Gears: These are responsible for changing gear ratios by meshing with other gears. Tooth wear can lead to noise and gear shifting problems.
• Bearings: Support the shafts and allow them to rotate smoothly. Worn bearings can cause noise, vibration and overheating.
• Synchronizers: Enable smooth gear changes by synchronizing the shaft speeds. Damaged synchronizers can cause grinding noises and difficulty shifting gears.
• Seals and gaskets: Keep the gearbox tight, preventing oil leaks. Replacing seals is necessary in case of leaks.
• Shift levers and cables: Transmit the movement of the shift lever to the transmission mechanism. Damaged cables or levers can make shifting difficult.
• Transmission Housing: Protects the internal components of the transmission from contamination and damage. A damaged housing can lead to leaks and damage to internal parts.
