Excess oil can accumulate on the shaft seal and joint surface when the gearbox is overfilled. This accumulation creates added pressure on the seals and gaskets, causing them to degrade over time. These compounds work along the same lines as radiator sealants that form deposits at the point of leakage. As with introducing any aftermarket product to your oil, this should only be done after careful consideration and testing to ensure there will be no ill effects on the oil or machine. Also, if the seal isn’t installed properly during assembly, it may not create a tight enough seal to prevent oil leakage. 4. Pressure Differences and Structural Design Provided that the component can be taken down and repaired in the near future, there are some options to “Band-Aid” the problem. Several manufacturers make compounds that can be added to the oil to help mitigate leakage.

To stop oil leaking in your gearbox, you must identify the leaking area by inspecting the gearbox for signs of oil leakage. After that, drain the gear oil from the gearbox and clean the leaking area thoroughly to ensure a proper seal. Apply a high-quality sealant to the leaking area and allow it to dry. The first and most crucial step is to identify the source of the gearbox oil leak. Inspect the gearbox area for visible signs of oil to identify the leaking area. Examine the gearbox underside, looking for oil stains or drips on the surface. If the sealant has done its job, there should be no further leakage observed. During the inspection, pay close attention to any potential leakage points.

Locate the drain plug on the gearbox and remove it to allow the oil to drain into a suitable container positioned underneath. The drain plug is typically located at the bottom of the gearbox and is easily identifiable by its hexagonal shape. Shut down the machine and isolate it from any power source. Thoroughly inspect the gearbox to locate the source of the leak. This may involve removing any covers or panels to gain better access. When this happens, the O-rings lose their ability to seal the gearbox, resulting in oil leaks effectively. Regularly inspect the O-rings for any signs of wear or damage and replace them as necessary. 3. Gear Drive and Engine Seal

The excess pressure can also lead to the formation of leaks at weak points in the gearbox, such as damaged seals or worn-out gaskets. Also, the excess oil can create turbulence within the gearbox, further contributing to leaks. 6. Improper Maintenance and Low-Quality Parts Can be added to all conventional ATF fluids meeting Dexron II, III or VI, Ford, LHM or equivalent specification Throughout this article, I will discuss these steps to stop gearbox oil leaks. I’ll also discuss why this happens so you can take preventative measures in the future. How to Stop Gearbox Oil Leak: 6 Steps to Follow I’ve noticed that improper maintenance and the use of low-quality parts can contribute to gearbox oil leaks. Neglecting basic maintenance practices, such as failing to remove dirt from the joint surface or not replacing seals on time, can create gaps and openings through which the oil can escape. Filling the gearbox with grease is another simple solution that has been used successfully. Grease has lower flow characteristics than oil and will not leak as fast. While grease will lubricate the gears effectively, more heat will be generated within the gearbox. Since grease does not dissipate heat as well as oil, the temperature should be monitored.

When facing a gearbox oil leak, a suitable sealant to consider is Liqui Moly’s Gearbox Oil Leak Stop. After draining the gear oil, thoroughly clean the area around the leak to ensure a clean surface for the sealant to adhere to and effectively stop the gearbox oil leak. Use a suitable cleaning solvent or degreaser to remove any residue, dirt, and grime effectively. All of these solutions are not true fixes but simple patches that can help until the gearbox can be taken out of service and properly repaired. Keep in mind that after adding anything to a component other than the appropriate lubricant, it should be removed and the interior surfaces flushed to eliminate all risks of cross-compatibility. All seals should also be replaced to reduce future leakage. I have found that a common reason for gearbox oil leaking is the presence of worn seals and gaskets. These essential components play a crucial role in maintaining the integrity of the gearbox by preventing oil from escaping. If you’re looking for a product to stop just about any kind of leak, you’ve probably heard of Blue Devil. Blue Devil has been in the business of stopping leaks since 1997 and has had plenty of experience doing so over the years. As with a lot of problem areas, they’ve designed a product to help stop leaks in transmissions as well in their Blue Devil Transmission Sealer. With one main goal in mind, this product is easy to sum up:
