Removing Trans Pan Sealed With Rtv Sealant

Removing a trans pan sealed with RTV sealant can be a tricky task. The process may involve using a combination of tools such as a scraper, screwdriver, razor blade, or wire brush to break through the RTV and clean the surface. It is important to be careful during this process to avoid damaging the pan or the mating surface. In addition, it is recommended to use the correct type of RTV sealant that is compatible with the transmission fluid and to follow the manufacturer's instructions for application and curing time to ensure a proper seal.

Using a plastic scraper to remove RTV sealant

Start by acquiring a plastic scraper suitable for the task. Ensure the scraper is made of a durable plastic that will not break or deform easily. It should have a comfortable grip and a sharp edge for effective scraping.

Before beginning the removal process, protect your hands with gloves and ensure the work area is well-ventilated. If there are any large chunks of RTV sealant, use a screwdriver or a similar tool to gently pry them off without scratching the surface.

Now, carefully insert the plastic scraper between the RTV sealant and the surface it is adhered to. Gently push or tap the scraper to cut through the sealant. Work your way around the entire surface, scoring as you go. Be mindful not to apply too much force, as this may damage the surface.

Once you have cut through the majority of the sealant, use the scraper to gently peel and lift the RTV sealant off the surface. Work slowly and carefully to avoid leaving any residue behind. If necessary, use a plastic scrubby pad soaked in vegetable oil to remove any remaining traces of sealant.

Finally, clean the surface with a suitable solvent or cleaner to ensure all residue is removed. This will ensure a fresh surface for the new application.

Using a plastic scraper is a safe and effective method for removing RTV sealant. It may require some time and effort, but it is a reliable way to remove the sealant without causing damage to the underlying surface.

Cleaning the mating surface with brake cleaner

When removing a trans pan sealed with RTV sealant, it is important to clean the mating surface thoroughly to ensure a good seal. Brake cleaner can be used effectively to clean the mating surface, and there are a few ways to go about it.

Firstly, it is important to note that the mating surface refers to the surface of the cylinder block. This surface must be completely level before proceeding. If the mating surface is pitted, you will need to use a gasket sealant or RTV silicone to fill in the pits, as most gaskets cannot handle pitting.

One method for cleaning the mating surface with brake cleaner is to spray it onto a towel or rag and scrub the surface clean. This is a gentle and effective way to remove grime and old gasket material without damaging the soft aluminium surface. You can also use a razor blade to carefully scrape off any remaining gasket material, holding the blade at a 90-degree angle to the surface and scraping in one direction only. Be extremely careful not to angle the blade or push it too hard, as it can easily cut into the aluminium.

Another approach is to use brake cleaner in combination with a gasket scraper. Spray the cleaner onto the mating surface and use the scraper to gently remove any remaining gasket material or grime. Be sure to use a plastic or wooden scraper, as metal scrapers can damage the soft aluminium. You can also use a plastic putty knife or a solvent such as acetone, chemical gasket remover, or alcohol to clean the surface.

It is critical to ensure that the mating surface is completely clean and dry before installing a new gasket. Any residue can interfere with the seal and cause leaks. Additionally, if you are using adhesives or RTV silicone, it is important to clean the surface with brake cleaner to remove any oil, as it will not adhere properly to an oily surface.

Using a wire wheel to clean the mating surface

When removing a trans pan sealed with RTV sealant, it is important to not scratch the trans mating surface, as this can cause leaks.

A wire wheel can be used to clean the mating surface. This can be done with an air-powered wire wheel, or a wire wheel attached to a die grinder. It is important to be careful when using a wire wheel, as it can scratch the mating surface. Other tools that can be used include a razor blade, a carbide scraper, a plastic scraper, a brass wire brush, or a glass scraper.

When cleaning the mating surface, it is important to not use abrasive materials, as this can damage the surface. Instead, use a wire wheel, a razor blade, or a carbide scraper to remove any residue or corrosion. It is also important to keep the surface clean and free of debris, as this can affect the sealing process.

In addition to cleaning the mating surface, it is also important to choose the correct type of RTV sealant. Only certain types of RTV are compatible with trans fluid. It is recommended to use a sealant that is specifically designed for trans fluid, such as Stellantus, Permatex, or Threebond.

By following these steps and choosing the correct tools and materials, you can effectively clean the mating surface and remove the trans pan sealed with RTV sealant.

Using a wire brush attachment for a battery drill to clean the mating surface

When removing a trans pan sealed with RTV sealant, it is important to not scratch the trans mating surface, as this can cause a leak.

A wire brush attachment for a battery drill can be used to clean the mating surface. This method is efficient, powerful, and easy to use.

Before using a wire brush attachment, it is important to consider the type of wire brush and the material of the surface. For softer materials like rubber and aluminum, brass-coated wire brushes are ideal. Carbon and stainless steel brushes are designed for specific materials and using the wrong type may damage the surface or cause contamination.

Wire thickness is another factor to consider. Thin wires are less than 0.014 inches and are suitable for light-duty applications and softer materials as they are more flexible and fatigue-resistant. Thick wires, measuring over 0.025 inches, are designed for heavy-duty jobs and stronger materials.

Wire brushes also come with different bristle configurations. Crimped wire brushes are ideal for light to medium-duty jobs and irregular surfaces as they provide more flexibility and a more uniform result. Twisted knot wire brushes are designed for heavy-duty cleaning and rigid hold.

When using a wire brush attachment, it is important to take safety measures and avoid excessive speed to prevent the bristles from dulling and breaking.

Using a razor blade to clean the mating surface

Once the RTV sealant has been removed, the mating surface can be cleaned. It is important to be careful during this process, as applying too much pressure with a razor blade can gouge the aluminium. Lightly draw the razor blade across the mating surface, removing any remaining residue.

Alternative tools for cleaning the mating surface include a carbide scraper, nylon brushes, fine-strand wire brushes, and 3M Bristle discs.
