A gearbox is a crucial spare part in any mechanical equipment, making its maintenance essential for optimal performance. Regular inspection and maintenance of Ford spare parts, especially used gearboxes, require careful planning. Curious about what key checkpoints are involved in maintaining gear and a gearbox? Read on to learn about the most important items to include in your Ford gearbox inspection checklist.

The Checklist

Thoroughly inspecting all aspects of a gearbox and gear increases the chances of achieving top performance. Here are key points to consider:

Check the Gearbox Ratings 

It’s crucial to verify the thermal and mechanical ratings of the gearbox and ensure it operates according to the manufacturer’s specifications.

Clean the Gearbox

Gearboxes often operate in dirty or dusty environments, which can lead to contamination and reduced efficiency. Thus, regular cleaning is essential for its optimal performance.

Check for Oil Leaks

Ensure there are no oil leaks, as they can significantly affect performance. Oil leaks, often caused by failing shaft seals, which allow water, dust, and debris to enter, compromise lubrication. Thus, it is vital to regularly inspect the shaft seals to avoid this issue.

Ensure Correct Breather Types and Style

Make sure the correct type and style of breather are used. This prevents dust, water, and debris from entering the Ford 6-speed gearbox while allowing it to breathe properly.

Perform Regular Lubrication

Regular and proper lubrication is essential. Follow the manufacturer’s specifications for grade, type, and quantity to ensure optimal performance.

Avoid Overheating

Use an infrared temperature gun to monitor any sudden temperature changes. Avoid overheating by looking for signs such as discoloured exterior paint.

Check Gear Contacts and Wear

Periodically inspect the gearbox for wear and check for misalignment of the gear teeth. Regular checks help maintain the Ford gearbox’s efficiency and longevity.

Perform Vibration Analysis

Gearboxes often operate in noisy environments, making it easy to miss their noise level changes. Conduct vibration analysis to monitor gearbox noise and vibrations closely.

Check Shaft End Play and Backlash

Use a dial indicator to check for increases in end play at the output or input shaft and for increases in backlash between the gears.


This checklist covers essential steps for inspecting gears and gearboxes. Following these recommendations ensures all crucial aspects are covered.
