If you're unsure, opt for a GL-4 oil, which is generally considered safe for all gearbox types. Don't skimp on quality when it comes to gearbox oil. Investing in a reputable brand can provide better protection and extend the life of your transmission. Read reviews, compare specifications, and choose an oil that meets or exceeds the manufacturer's recommendations. Remember, the gearbox is a critical component of your tractor, and using the right oil is a small price to pay for ensuring its continued performance and reliability.

Checking the Gearbox Oil Level

Regularly checking the gearbox oil level is a simple yet vital maintenance task. Low oil levels can lead to increased friction, overheating, and accelerated wear. Fortunately, checking the oil level on a Fordson Super Major is usually straightforward. Locate the dipstick or level plug on the gearbox housing. This is typically found on the side or top of the gearbox. Before checking the level, make sure your tractor is parked on a level surface. This will ensure an accurate reading. Clean the area around the dipstick or level plug to prevent dirt and debris from entering the gearbox. If your tractor has a dipstick, remove it, wipe it clean, and reinsert it fully. Then, remove it again and check the oil level. The oil should be between the minimum and maximum marks on the dipstick. If your tractor has a level plug, remove the plug and check if the oil is level with the bottom of the hole. If no oil comes out, the level is too low. If the oil level is low, add the recommended type of gearbox oil until it reaches the correct level. Be careful not to overfill, as this can also cause problems. After adding oil, recheck the level to ensure it's correct. It's a good idea to check the gearbox oil level every 50 hours of operation or at least once a month. This will help you catch any leaks or other issues before they cause serious damage. While you're checking the oil level, also inspect the oil for any signs of contamination, such as water or metal particles. If the oil appears milky or contains debris, it's time to change the oil.

Changing the Gearbox Oil

Changing the gearbox oil is a crucial maintenance procedure that helps to remove contaminants and ensure proper lubrication. Over time, gearbox oil can become contaminated with dirt, metal particles, and water, which can reduce its effectiveness and lead to wear. The recommended interval for changing the gearbox oil on a Fordson Super Major is typically every 500 hours of operation, but it's always best to consult your tractor's manual for specific recommendations. Before you begin, gather the necessary supplies, including the correct type and quantity of gearbox oil, a wrench to remove the drain plug, a drain pan to catch the old oil, and a funnel to pour in the new oil. It's also a good idea to have some rags or paper towels on hand to clean up any spills. To start, warm up the tractor's engine slightly. This will help to thin out the oil and allow it to drain more easily. Then, locate the drain plug on the bottom of the gearbox housing. Place the drain pan underneath the plug and use the wrench to remove it. Be careful, as the oil may be hot. Allow the oil to drain completely. This may take 30 minutes or more. Once the oil has finished draining, inspect the drain plug for any damage or metal particles. Clean the plug and replace the sealing washer if necessary. Reinstall the drain plug and tighten it securely. Next, locate the fill plug or filler cap on the gearbox housing. Remove the plug and use the funnel to pour in the new gearbox oil until it reaches the correct level. Refer to your tractor's manual for the correct oil capacity. After filling the gearbox, replace the fill plug or filler cap and tighten it securely. Start the tractor's engine and let it run for a few minutes to circulate the oil. Then, stop the engine and recheck the oil level. Add more oil if necessary. Dispose of the old oil properly according to local regulations. Never pour it down the drain or into the environment. By changing your gearbox oil regularly, you can help to extend the life of your Fordson Super Major's transmission and ensure its continued performance.
